I might be able to help. Can you tell me what kind of motor you have,
permanent magnet, series wound, or shunt wound, and what the symptoms are.
Based on your message the field winding seems too high. Does the motor run at
reduced speed? Do you know how much current it draws? Is the controller applying
the right output voltage? What voltage are you using?
I designed and built my own motor controller without any problems, so I
have some knowledge.
