RP5 motor problems

Hello all,

I have an RP5 chassis which I’m currently driving from a stabilized ATX supply, using orangutan SVP as the driver / controller @ 12V.
left track (for our discussion purpose) is responding great while right track gets stuck once in a while (when starting from a complete halt) and I need to “release” it by turning the driving wheel with my hand a bit in the rotation direction.
I feel a slight opposition and then it starts turning as normal.

when powered off it seems loose as the left track and the sprockets seems intact.
anyone encountered such a problem or has a suggestion for solution?

Regards,
M.

Hello.

Can you try to identify the part of the system is sticking (e.g. the drive motor, the track, or the sprocket)?

Hi again and sorry for the delayed reply.

The part sticking is obviously the motor itself, the transmission is working fine and I measured with a scope the input to the motor and its a clear, healthy PWM signal.
Is there something to be done about the motor or is it a lost cause?

Regards,
M.
