shunt wound motor control
shunt wound motor control
(OP)
Have a small 1/50th shunt wound gearmotor with output speed of 57 rpm. I want to just run it at constant speed 57rpm output. I have a controller that is meant for a PM motor.
It has 90v dc out and a pot. Could I use this simple controller and connect both the armature and field to the 90 v source and just not vary the pot. Field is rated for 100v. What I be creating a dead short? Your help is appreciated.

What does the circuit look like with the 4 1N4004 diodes.
And I think you suggest connecting this circuit directly to the incoming 115v ac.

First: Disconnect field windings from armature.
Second: Hook up the diodes as shown. Observe polarity!
Third: Connect the field winding to the + and - terminals.
Fourth: Connect mains 115 V to the free terminals.
