High torque, low speed motor

[dos4gw]

Hello,
The default motor on the Rover (S10 Twister) has a low torque and is hard to control using RC override (PWM) at low velocity. I'm wondering what would be a good alternative to the default motor? I need a low-speed but high torque motor so I have better control of the rover at low speed (1-2 m/s).
Thanks.

Hi @dos4gw,

sorry, but we don't modify the default motor. But I'm sure you can found this kind of motors.

Have you searched on google?

Sure, I did the searching first - there are plenty of such motors. I was hoping someone already hacked the Rover for the same purpose and can share some details.

Dear dos4gw,

did you find a replacement motor and tested it? We are having same problem and are looking for a suitable low speed motor. Thanks!

Dear all,
As far as I know, there are only two ways to deal with this:
1) As you suggest search for a high torque & low KV motor (i.e. higher moment of force per RPM & less RPMs per volt) or
2) Add a planetary gear to your motor (see https://en.wikipedia.org/wiki/Epicyclic_gearing).
Try "1" first. If unsuccessful, make some numbers to get the torque ratios and google for a gear that suits your motor.
Cheers !
