Stank Posted January 24, 2011 Posted January 24, 2011 So, the question is-will it damage the motors? i saw the comments and they said it can damage the motors but i think i will get better answers here. Link: I don't have 2 motors, only one. i'm just curious to know. Sorry if this has been posted before. Quote
backbone Posted January 24, 2011 Posted January 24, 2011 I think this won't cause any damage to the motor. This is simple sample of electrical generator. http://en.wikipedia.org/wiki/Electrical_generator Quote
Zerobricks Posted January 24, 2011 Posted January 24, 2011 Yes it may cause. If you wind the motor faster tahn it was made for and also if you generate more current than what the coils in the rotor were made for. I use to play with a 9V geared motor this way AND IT BROKE. Quote
grohl Posted January 24, 2011 Posted January 24, 2011 Any electro motor can work also the other way-as the alternator. Yes, it may damage your motors, but people from Czech forum often use XL motors to steer their rally cars-the steering is not that fast and more accurate. But you have to use cables to control your car. Quote
BrickDemon Posted January 24, 2011 Posted January 24, 2011 I don't think it will damage the motor, it's just the gear ratio that makes it hard to turn (and so you might damage the gears).. the new E-motor that is realeased with the solar panel (for educational purposes) has been geared just for this purpose.

But damaging the gears=damaging the motor right? I know about the E Motor but i have only 1 M-Motor and 1 battery box. So it will damage motors a little but if you spin it fast they will break? Also, my M-Motor makes a weird sound after working 10-15s (like buZZZZZZZ), but it doesn't lose power or anything. Quote

I have the same experiente as zbjl If you turn by hand the gears in the motors DON'T like it Quote
fmmjqtft Posted January 25, 2011 Posted January 25, 2011 It can damage the motor, but it depends on how fast you turn it and how loaded the other motor is. Once I made a custom Lego motor using the motor from a 14.4v drill, then connected it to one of my modified PF XL motors: (pictures of the modified XL motor) The coils in the PF XL core broke and went everywhere - but nothing else. Even the modified PF XL gearbox remained intact. I have tried many other arrangements just using PF elements and only this one damaged a motor. ps. I have used the 14.4v drill motor for other things and it generally melts gears/axles/axle holes unless a very low-pw pwm signal is used. I might try using it again but gear down using metal pieces.

BrickDemon Posted January 25, 2011 Posted January 25, 2011 (edited) But damaging the gears=damaging the motor right? right! the gear ratio vs gear strength is designed for input from the inside.. Edited January 25, 2011 by BrickDemon Quote
