LEGO Motor DIY Part 1: Make a Technic Cross Axle Coupler and Bracket

Make a Technic Cross Axle Coupler and Bracket on general DC Motor can be connected with other LEGO Technic, Pneumatics, Power Functions and Mindstorms EV3 parts, to create your own LEGO compatible DIY-Motor.

The music in this video made me imagine I was marching through a magical forest with a band of elves, gathering ingredients for a magic potion that we'd take back to our magic elf home, where a great and powerful wizard would brew it, and then we'd eat magic elf cookies and spend the rest of the evening dancing and playing and having a wonderful time. I can't comment on the video because I was too busy thinking about this to pay any attention.

You, my friend, are a genius

[@biankro]

Very nice work! I would ask you how to do a steering motor: should i need a stepper motor or a DC one could work as well? Ty

[@ag6371]

Use LEGO Servomotor/Unipolar stepper motor

[@ag6371]

LEGO Servomotor will turn 180 while the stepper motor can turn 360 as well as turning precisely

[@LegoGBC]

Cool! It looks like it will need a lot of gear reduction,though

[@TechnicRobot]

yes, general brushed DC motor is high speed but low torque, so need to build a gear box to drive LEGO Technic parts

[@dinhtuan752]

or used a belt.

[@bwface5362]

This things are so cool

[@robertoricciardi6854]

Hi I have a question for you .... Can rc suspensions be mounted on a moc?

[@lio_2142]

What size of bolt and washer you use in this video? i can't find bolt like this

[@pjurkovi]

Instead of copper tube I used pneumatic hose and it works, without epoxy or glue.

[@TechnicRobot]

pjurkovi thanks for your feedback, is it ok when applying higher torque?

[@petarjurkovic]

TechnicRobot Yes.

[@fernylloyd1975]

lol i wanted to do this but my motors were weak but they were bigger than the one you used.

[@Klaevin]

this looks cool, except that I don't think that I would be willing to disfigure five lego pieces to get this. although, how customizable is the motor? I mean, how easy is it to modify a generic DC motor?

[@TechnicRobot]

yes, the motor is a generic standard type 370 motor

[@waynecure32]

You helped me out a lot thank you

[@Deluxechiller]

really nice

[@TechnicRobot]

It is standard 370 motor, part number: RF-370C XTL-13470. But you can search any this type of motor.

[@cameronmorgan5360]

Could you give me a link to which motor exactly, I don't want to buy the wrong one :/

[@dinhtuan752]

Custom high spees motor without geared

[@andyfunkstep]

which 2 wires you connect to the motor? Lego cable has 4 wires, I mean which 2 of them I should connect to motor for IR control

[@jaromy03]

Andrew Gurtovoy it should work if u connect the 2nd and 3rd wire, C1 and C2

[@dinhtuan752]

[@massonmilo5754]

Wow! I was shocked.Keep up the.

[@MrTomasMaliauka]

Nice job. But are you aware of the maximum permissible current for the EV3 controller output? If you exceed it controller output will burn out. If you use powerful enought 9 Volt motor it will demand too high current from EV3 controller output.

[@maninalift]

Or save more money and don't use a lego controller.

[@Pete-nw3jr]

any suggestions on where to find the copper tubing? I can find it in 4mm outer-diameter, but not in 2mm inner-diameter... :^(

[@TechnicRobot]

can you find 4mm outer, 3mm inner and 3mm outer, 2mm inner? then you can try to combine 2 copper tubing

[@Pete-nw3jr]

you read my mind! I got those 2 pieces but the 3mm outer wasn't 2mm inner. I could be wrong, I test fitted it on the shaft of a 280 motor I had, maybe the shaft isn't 2mm. I ordered a 370 motor, when it arrives I'll see if that fits what I have. Thanks for the reply! PS what did you use to connect the motor to the receiver?

[@TechnicRobot]

i cut the original lego power fuctions extension cable and used JST connector to connect the motor and power functions plug

[@yungtrastin834]

nice

[@rkkm-gameplay9649]

What about its power? similar to normal lego motor?

[@mileskosik472]

Nice idea. Do you use a film camera? Just curious.

[@TechnicRobot]

i use general digital camera with manual setting :)

[@billydeutsch8239]

cool

[@mvshabeer]

how does this motor compare to XL motor in terms of torque/speed

[@ag6371]

XL Motor will be slow than DC Motor, which will be fast

[@lgbonfim]

I used a HP printer motor to do mine!

[@andreashobby]

long time ago but is it that motor: DC 9 V 0,01 A 2600RPM Rotary Speed 2 Pin elektromagnetischen Gear Motor www.amazon.de/gp/product/B00BGC7I92/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 I am just wondering about the 0,01A - which could not make similar torque as LEGO L motor. But I did not found any spec for that motor.

[@tombaxter716]

how much would you charge to make me one and sell it to me? (I live in Pyrford UK )

[@stephenlee306]

Where did you buy those screws?

[@chrisadams7216]

Hry mate love your vids I seen on a diffrent persons vid a rechargeable battery pack plugged into a power functions motor and in fared recceiver any ifeas how you do it

[@TechnicRobot]

thanks, you mean official LEGO rechargeable battery box or non LEGO rechargeable battery plugged into power functions motor and infrared receiver?

[@chrisadams7216]

Non lego one

[@jessesanders6358]

now how will i do this with a castle creations brush less motor

[@DutchReptilesOfficial]

hahahha that will break your legos

[@sergioferreira5771]

time to mold aluminum legos

[@ELValenin]

It will absolutely destroy your Lego.

[@sd-qu4nt]

Is it OK to insert miniscrew into motor?

[@m.agilnajib345]

김기리 i assume the holes were designed for screwing the motor to a bracket/mount

[@jasoncramer5091]

how did you wire the motor

[@ag6371]

PIN + has to go to PF C2, and PIN -- has to go to C1. Do not connect 9V supply, and ground wire

[@dinhtuan752]

@@ag6371 ok

[@driftpro4872]

that music ha, i did this with a motor from a himoto rc buggy and the glue wasn't enough...

[@TechnicRobot]

i used the epoxy for bonding ABS and metal, should be ok. you can take a look LEGO Motor DIY Part 2 & Part 3 :)

[@driftpro4872]

okay cheers

Можете показать как сделать Багги мотор?

Где можно достать такой мотор ?

Vladis volit is the standard motor type 370, you can search similar motor on the web.
