NEO traction motors problems

Hello,
in the middle of 2016 I've changed the customers faulty "old type" traction motors with "new type NEO" motors because the WAVE had bad steering and braking. Actually I did this on a lot of WAVE's cause it's a common issue.

Two months ago the same issue with the new NEO motors appeared. Did the testing and the right motor rotor had bad windings. We rewind the rotor and overhaul it completely. Put it back on the WAVE this time on the left side.

After of moth of working the other motor, now on the right side goes bad also.
Now I have two new motors going bad in maybe 40 hours of work.

Checked the motor wiring to control unit - OK. Check the control unit power supply - OK. Check the output power supply via Curtis handset - OK.

If you have any info regarding problems with NEO motors please share.
If you would like to start a tought process and comment I'll be happy to reply.

Thanks!

The motors had a burnt commuutator. Old type motors were not worth repairing because after a short time they were burning again. I heard that it could be the fault of brushes. Some are made of poor material.

Dziadzia,
the motors worked for 900 hours, but there was only 40 hours between both going bad.

What happen to your motors?

I've never had problems with neo engines after such a short time. The fastest error occurred after 1100 hours.
