[@GRAHAMAUS]

@1:19, just to clarify what you're saying. The Hall sensors provide feedback on the rotor's position to the controller, so that it can properly drive the main phase connections. The Hall sensors do not create or manage the torque, that is all done by the main phase windings. The current in the Hall sensors is tiny -- a fraction of a milliamp.

[@diypotentials]

Thanks for that clarification. You've explained it much better than I did. @1:35-2:00 I explained that the hall sensors collect information by sensing the magnetic field of the rotor, from there the sensors would inform the controller to provide specific magnetic field to interact with the rotor, meaning that the controller would release the electricity needed from the battery to generate the magnetic field in the specific stator poles or phases, therefore would generate torque against the magnetic fields of the rotor. You are absolutely correct, the current in the hall sensors is tiny. Thanks again.

[@diypotentials]

Hello. Sorry to hear. My suggestion is to connect the leaning wires together. If that doesn't work, the next thing I would do is try to switch the phase wires from the controller to the motor- Sometimes the colors don't match. Try to switch one wire each time and test it. THIS is very IMPORTANT, when you switch the phase wires, you also have to align the Hall sensor wires as well. Be careful. Good luck...I hope that will work. Thanks!

[@spacefightertzz]

Nice video. I was just wondering what the wires were to the motor. I'll need to watch this again when I look at my escooter. I did a quick fix on my kugoo m4 pro. I had banged/scrapped the wires that go to the motor. When I tried to accelerate then the motor would make like a vibrate noise and had very little power. So looking at the wires, I cut off the rubber protective and seen 2 thin wires were disconnected and the thick wires were fine. I connected the broken wires them by twisting together and duct taped it for now and scooter is working good. Just a quick fix until I get a soldering iron.

[@diypotentials]

Good job! Glad you fixed it. Thanks!

[@hrcsteubenville2187]

I have an escooter that just died. I installed new batteries and I get nothing. How can I trouble shoot the controller. You are the best in explaining how things work and troubleshooting. Thanks for your videos.

[@diypotentials]

Sorry to hear that about your e-scooter. There are so many electronic components and parts involved that it is hard to pinpoint the problem. It could be the controller, a blown fuse, the hall sensors not working, or a wire not connected properly to the motor. I saw several videos that might be helpful for troubleshooting the controller. kzbin.info/www/bejne/m6eVe2mfppqnask, kzbin.info/www/bejne/ooXWpHakar6sitk, kzbin.info/www/bejne/hH_XeH2JYs96mpY&pbjreload=101.

[@ahmadzaki3328]

Thanks for the video. What do you think of running the motor without the speed controller. Meaning can i just connect the motor to the highest rate of the battery at once?

[@diypotentials]

From my experience, a BLDC motor needs to be connected to a controller and will not work if directly connected to a battery. Once connected to a controller, you can set the desired current to run the motor. Thanks!

[@gsrbooster]

I just got the same throttle and was trying to figure out to how to connect it, so thank you for making this vid. Since the throttle has a voltage meter and it's directly connected to the battery, do you think a fuse between the two connection is necessary? I've seen some users do it with other voltage meters and others who don't.

[@diypotentials]

If you are connecting it through a controller, I don't think a fuse is necessary. I use the throttle on 36V 30AH lithium-ion battery pack without a fuse and no problem at all. Take a look...kzbin.info/www/bejne/mWe8mIGHnJiJg5o. Thanks for asking...

[@harshmaithani]

Amazing video! I was looking for this. Just one question - Is it really necessary to buy the motor controller? Is it not possible to control the motor directly from an Arduino (I have seen this in some videos) ? and also MATLAB/Simulink have a Motor Control Toolbox, would it work ? Thanks in advance!

[@diypotentials]

I haven't not try it with Arduino. So I would not be able to say yes or no. The controller is specifically designed for the motor as it also comes with other features for controlling your ebike, scooters, etc. Thanks.

[@marcmihelich971]

Does the controller step down the voltage for the "on off switch" or do you need a toggle switch that matches that batteries voltage?

[@diypotentials]

The controller is rated for 48v. For the throttle switch, the controller will allow a small amount of voltage to do its job. Thanks!

[@richardesposito6622]

HI! Thank you soo much for sharing your thoughts with all of us re ebike controllers! I have a 2008ish 500watt 36volt AC hubmtr. with a 7 speed Shimano, throttle type ebike from the landfill! I can't find Battery, housing, charger and BMS and I believe the controller is in the hub. Connector to the battery has 6 pins 4 large pins and 2 small and the one to the hub has 5 small only two large pins. Spent hours of research, learning but still afraid to buy a possible battery, BMS and charger for it. I have had the ebike for months and I just want to go out get some exercise and experiment with this more. Also read I may need to change the throttle to a potentiometer type and I would need to getting bike rolling for the wheel to start rotating. Not a problem for me to do that and cooling down with fins or holes to stop any overheating is also. Cant I just get a get an LI 20 amp battery kit with BMS, charger with a SW/fuses and not the 30 amp controller you are showing here? I think I saw a 1-5 volt potentiometer on your other video but not sure where to get it? Way grateful for any thoughts on this!

[@diypotentials]

Hello, I'm not familiar with the hub-motor you described, so I won't be able to give any feedback on that. However, I don't think the controller is in the hub. There might be a hall sensor circuit inside the hub, though. But I might be wrong. Also since the motor is rated at 500 watts at 36V, it needs about 14 amps to reach 500 watts at 36V. So if you are planning on getting a controller, any one able to handle 14-20 amps or more would be sufficient, even the 30 amp one so long it is rated for 36V. For battery, a 20 AH (amp-hours) will be sufficient. Of course the more AH the battery has, the more run-time you will get. I found a video that might be more helpful..kzbin.info/www/bejne/d2m0lIGsh81jra8. Best of luck. Thanks!

[@richardesposito6622]

@@diypotentials Thanks again for looking at this and commenting here! With this I am getting a little more confidence on purchasing the controller you have here along with an Li battery/BMS and charger may just get it to work! I love that throttle you have here too! Not many frills on this ebike so just a Voltage reading is great for my needs. My mistake on the Hub Mtr pin out it's really a 7 pin push and screw on plug. There are 5 small male pins on it. I am guessing these may be 5 vdc for the hall sensors plus the throttle? Not sure yet until I test those leads and look further. If so what you are noting above makes more sense. I know it has a thermistor in the hub for overheating conditions but no direct pinouts for that. Enjoy your day and Kind Regards!

Thank you for the details video, but how do you mount the hall sensor, my package actually has the hall sensor separate, where do I put this sensor onto the bike?

Hi there! Thank you for your great explanation! I have one question. Would the 4x 12V batteries connected in parallel be enough to power, for example, a small buggy? Or would powering something like this require more power? Thanks.

[@diypotentials]

It depends on the power requirement of the buggy. If the buggy is rated for 12v, then the answer is yes. Connecting the batteries in parallel will not increase the voltage level. If the buggy is rated for 48v for example, you have to connect the 4 12v batteries in series to get the 48v needed. I hope this helps!

[@pathumdanthanarayana9740]

@@diypotentials Thank you! Another question I had was, would 48V be a high enough voltage to power a 4-wheeled small vehicle like a golf cart for example? I assume 48V is plenty to produce high speeds for a bike since it is low weight, but would 48V be sufficient for achieving high speeds for a heavier vehicle like a golf cart or would a higher voltage need to be used? Once again, thank you so much!

[@diypotentials]

@@pathumdanthanarayana9740 It depends on the golf cart's specific voltage requirement. If it is rated for 48v then you can power it with 48v. If it is rate for 36V for example, then 48v would be to much for the engine to handle. Over time you can damage the engine. The heavier the vehicle, the more energy it will use, which means that it will draw more amps out of the batteries to meet the weight and speed needed.

Would you reckon this motor would be good enough or would it be too fast or too weak? Honestly, I know it is a very odd question but just curious and looking at the market.

[@diypotentials]

Sounds like a fun DIY project. The motor might not be powerful enough. If you have access to AC power, that might be a better option, then you can use an AC motor with maybe 2 horsepower or so. Brushed DC motor might be easier to connect, but you will need a good size battery bank. You will eventually need to charge the battery. Here are couple of videos that you might find helpful.

I used 14 AWG wires to connect the batteries in series to form the 48v. If the controller and motor are rated for 12v or more, you might be able to test with one 12v. If not, you might need the full 48v. Good luck on your project…

Hey, I am looking to use this type of Motor controller with a microcontroller, so I am having trouble finding out the correct connections. I saw your other tutorial with the small motor driver and there are 4 digital pins, Z/F, VR, Signal and EL. So as far as I know, the equivalent of the VR would be the throttle cable, but aside from that I am kind of lost, as the small motor driver has a Signal pin which I've seen is for sensor feedback, but the only cables related to this are the three hall cables, so I think an equivalent to this would be an external encoder. Now, the Z/F pin stands for direction of the motor, and EL stands for Start/Stop, so I would appreciate if you could provide me some guidance on which cables from this motor driver would be equivalent to be connected to a microcontroller, as I can't seem to find a suitable schematic or datasheet of the motor driver.

Hello, you won’t be drawing 30A at a time. I recommend a 12 awg wire. Here is the wire current chart. If you think you will be drawing more amps, refer to the chart to the right rating for your project. Thanks! www.solaris-shop.com/content/American%20Wire%20Gauge%20Conductor%20Size%20Table.pdf

Great video bro please help me

Hello DIY man. Thank you for making this excellent video! It was must helpful. However, we have a problem with our setup! Every time we try to connect the positive wire to the battery, there is a big soak! We can't find any bad connections though. Do you have any ideas what could cause the sparking?

[@diypotentials]

Hello, that doesn’t sound good. Could be a number of things in the circuit. Check again if the batteries polarities are property connected. Other than that, it is difficult to tell without looking at your set up. So sorry!

Hello, I’m in Yellowstone this week. Very limited access to the internet. I don’t think you can bypass the controller to test the motor. My email is [e-mail]. I can help more after my vacation on July 5.

For a project I need this motor to turn the other way. I’ve tried swapping two phase wires and it didn’t work. Any suggestions? Thank you

[@diypotentials]

Does your controller have a terminal for reverse?

[@melrom5698]

Can you add a pedal assist on this kind of motor or this is only for full throttle?

[@diypotentials]

The pedal assist is managed by the controller. If the controller has a pedal assist port, then it should work on the motor…

[@eelcohoogendoorn8044]

Thanks for the review. I was thinking of buying this motor, but im rather put off by how noisy it is. Most high quality BLDCs are nearly inaudible; would happily pay double for something more quiet for my project.... but its hard to tell from the aliexpress page how noisy it will be in practice I suppose.

[@diypotentials]

Thanks! I’m glad it was helpful.

1 get a better controller . 2 this is a geared motor

[@MrSoto92]

what is the total amperage being supplied? Is it 28A?

[@crustytoenail1110]

I'm thinking of building an E-bike with a 48volt 2000watt permenant magnet motor. It doesn't have hall sensors. Any downfalls with my idea?

Hi and thank you for your great tutorial. I followed it completely to replace my former thumb throttle. I tried the new sensor on an external source first and it showed the expected 5V connecting the positive and the ground cable and low Voltage when connecting the Data cable with ground which would increase when I twisted the accelarator. Connecting the throttle to the controler and motor I quickly found that I had to switch the yellow and white cable in order to not have the display consistently on and the keys without function. With the cables switched, power supply seemed to be working as intended. However, while the horn and lights worked well, the accelerator did not work at all. When measuring with Voltmeter, the data cable of the throttle showed negative Volt value which would not change when I twisted the throttle. I can not explain to myself why that happened. I tried few other cable combinations but to have the key function working I could not find a way to make the sensor/accelerator work. Do you have any idea about what went wrong and how I can fix that? I would highly appreciate some help. Best wishes Fran

[@diypotentials]

The only thing I can think of is based on your description is that the throttle terminals from the controller and the accelerator might not be compatible. Sounds like you already tried and make sure the positive, negative and signal lines ( green) from both the controller and throttle are matched and connected. Sorry bro. Might be a disconnect in the throttle circuit…

[@franxx2498]

Hey actually that was quite helpful as it made me check Volt output for the Halle sensor at the controller and that is not the 5V needed. Now I can only think that I dont have Ignition and Switch assigned correctly as in my controller they are not easy to find. How can you recognize where to connect the blue and yellow cable from the throttle,. You connect the blue cable in the video to a red cable which comes directly from the main Battery cable or some side connector? Same is for the yellow cable to the Switch. In my controller I couldnt tell which one that is. And my last question. With this controller and throttel, can you connect front and rear light and a horn which all switch off with the key? I really wuld appreciate an answer as anything helps right now.
