Responding to: ???'s previous message
So the motor is not isolated from the mains ? You seem to be doing something very odd with the -ve terminal on the motor rectifier.

For a (trivial) start, you need a flywheel diode on the field coil - and some kind of interlock to make DAMNED sure that you don't drive the armature with zero field current.....
