AC Generators - EandM
An armature is any number of conductive wires wound in loops which rotates through the magnetic field. For simplicity, one loop is shown. When a conductor is moved through a magnetic field, a voltage is induced in the conductor. As the armature rotates through the magnetic field, a voltage is generated in the armature which causes current to flow.

dept.ru.ac.bdwinding 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.

pages.mtu.eduThe 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

www.brown.eduwell 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
www.courses.ece.vt.eduAs 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.
