The latter source is produced by a phase-controlled Therefore theĮxcitation field is fed from a constant DC voltage source, while the armature windingsĪre fed by a variable DC source. The armature circuit is much smaller than that of the field winding, controlling speedīy changing armature voltage is quicker than changing the field voltage. Used to produce a magnetic excitation field in the motor, whereas the armature coilsĬarry the induced motor current. As the name implies, the field winding is Or field winding and the armature winding. The DC brush motor also has two types of windings - the excitation In any electric motor, the DC brush motor consists of the stator (fixed) part and the ![]() The seven DC drive models, designated DC1 to DC7, are based on the DC brush motor.
