Shunt wound motors

Motor, shunt wound

Shunt-wound motor generally have 4 wires. Two connect to the (relatively) high resistance field and two connect to the much lower resistance armature.

In the shunt wound motor, the battery voltage is connected across the field winding. A steady current (equal to the battery voltage divided by the resistance of the field winding) flows in the field winding, causing it to become an electromagnet. These motors behave exactly like a PM motor, but with the permanent magnet replaced by an electromagnet. Usually the field winding is brought out separately from the armature, so the motor has four wires. With an ohm meter you can check that there are in fact two windings, a high resistance one (the field) and a low resistance one (the armature). To control the speed, connect the field winding directly across the battery and drive the armature from a controller as if you are using a PM motor.
