CHAPTER 11

The rotor contains the armature winding, which is the high-power winding of the DC machine. The slots in the lamination provide space for the armature coil. When operating as a generator, the armature winding is rotated through the field, generating a DC voltage that is delivered to the load. For motor operation, the armature winding

well the armature winding of a generator is cooled has a significant influence on the overall size of a synchronous generator. The cooling of the armature winding is dependent on a number of factors: cooling medium (air, hydrogen, water); insulation thickness; and overall electrical losses (1 2 R + load loss). As Figure 5 illustrates,

Synchronous Machines

As the rotor moves within the stator, the field induces voltage in the armature winding of the machine. This voltage is called the generated voltage in a generator and the back EMF in a motor. Its magnitude is directly proportional to the speed of the rotor, the strength of the field, and the effective turns of the armature.

DC Motors

winding is connected in series with the armature. Therefore, series field winding carries the armature current. Since the current passing through a series field winding is the same as the armature current, series field windings must be designed with much fewer turns than shunt field windings for the same mmf.

Armature coil wires - The coil wires in a PS starter armature are square in cross-section. •More compact winding than round cross-section wires •Greater output torque Surface commutator - The square shape of the armature conductors allow the surface of the armature to act as a commutator. Field coils - Conventional starters use field coils.
