Problem with DC motor for Xiaomi Mi Robot

Postby mkoev » December 31st, 2017, 4:48 am

Hi all,

My Xiaomi mi robot started making really strange grinding noises and I believe it's the DC motor. It also gets very, very hot, impossible to touch. I truly hope it's not the plastic gearing, because I have no idea where I can get spares for that. The vacuum is no longer in warranty and there are no service locations for Xiaomi where I live (Eastern Europe, Bulgaria) or at least I have not located any so far.

I found out that the motor is:

standard motor rp390-st / 24100/dv smhd217626

I think that the "smhd217626" has to do with ROHS only.

Any idea where I can get such a motor? I only found one chinese website and they sell in bulk I am afraid :(

Make a video and share.

Do you mean the wheel motor?

Ali Express for that. £20 each wheel to replace direct from China.

Have to replace the whole mechanism. But it is modular and easy to do.
