3kw E Bike Hub 72v Testing Without Battery or Controller - Free Energy Project - 11th February 2023

Greetings KZbin, In this video I'm showing you a basic way to test an electric bike motor hub which is three phase, This one in the video is a 3 kW 72 volt Ebike motorhub which I plan to use as a wind generator, in the next video I will see if I can get any power out of this thing by hand using a rectifier.
Please note you do need a half decent advice to do this properly.
keywords are rectifier wind turbine wind generator axial flux wind generator electric bike motor hub 48 volt 72 volt

Gavin, off turbines and about the bike side off things. I've a motor with six hall wires, the white being a speed sensor possibly, just tmy KT controller doesn't have a relating wire. All hall sensor colour wires are connected and th bike runs up to the set max speed. Just it's not adhering to level, assists, 1-5

Weldon Good work

Bolt Snow Shovels to the rim.... Instant Vertical Axis Wind Turbine!

I thought about something like that but just wouldn't be able to get the speed, The motor will hopefully go in the existing turbine frame and will get the speed alright. 👍👍👍👍

Hal sensors are easy: They need ground and +5V and as you have 3 of them, you have 3, 5V digital signal wires to choose from. What I have done before botching together RPM or Speedometers, is to use a random cheap bike computer. However as you'll have multiple pulses per revolutions, (half the number of pulses, as there are magnets) and that would require you setup the bike computer with a very small bike wheel diameter , to have the speed readout show RPM, You'll need build a dividing circuit: Get one or two CD4017 decimal decade counters ICs, for division by 10 or 100 between the Hal sensor and the bike computer. Another option is ordering a cheap programmable panel RPM counter from China, but that is the low effort, dirt cheap solution!

Thank you brother. I will read this properly when I get time. I've got a lot on my plate at the minute. Thank you very much

have a question: on various videos I see a lot of wattages, but!! what rpm is that? Now I am also experimenting with an E-Bike motor myself and to have an idea of what wattage is produced at how many rpm, I am curious if you also have this measurement??? Thanks in advance on behalf of another E-Bike bungler :-) kzbin.info/door/wMKvJEVvbbd2nyxPwNCdaw

for a 3kw motor that sounds like a very good price, love one of those on my bike

[@GavinFreedomLover]

I did think about putting it on a bike but the battery required would have taken a lot of work or a lot of money, neither of which I can afford at the moment. Cheers.

My big phase cables wore torn by my disc brake screw .. I got the soldered but no power still to my throttle do I need a new motor core ?

[@colinwhite144]

The three phace wires lug connectors you said heavy duty do you no where I can perchace thanks

[@dimitrimotor2861]

some controllers tell you how to connect it

[@dimitrimotor2861]

I know some of that stuff
