Hi,
Yes, I have to give the motor a push to get it going, and once it is it's fine. The speed is correct and constant.
I took the motor control board out today in case there was anything obviously amiss, and it looks awfully complicated with three identical circuits. I wonder if it's three phase? I'll whip the motor out tomorrow in case it has a dry bearing, although it turns easily enough.
Cheers, Pete.
