SEM DC Motor Issues

[m_c]

Try cleaning the commutator up, and see what happens.
Have you been aware of the motor running hot?

It could be a sign of the drive itself failing, as it shouldn't be putting out enough power to cook the motor, and the blowing fuses can be caused by a faulty drive.
If possible hook up an ammeter so you can see how much current the motor is using, and one so you can see how much the drive is using.

I will do that and see. Waiting to hear about brushes but the normal supplier is out of stock.

I dont think the motor itself has been running hot. Ill post some pics later.

The drive is fairly new, Sprint 1220i that I bought when my 1200 had issues and could not be connected directly to the CS Labs board. The big thing I dont have is a current reading which I should do, its nice to know specifically when it sounds like the motor is loaded (or not).

Ill email Sprint and ask for some info.

Ive ordered some pulleys as I believe I can get my 1.5KW Servo motor (destined for the Y Axis on Thor) as a temporary measure.
