The motor is mounted in a test rig that allows one to control the torque applied to the motor shaft and to measure both rpm and torque. The rpm sensor operates on a Hall effect principle and consists of a disk bearing on its periphery

home.iitk.ac.inThe armature winding is connected to a commutator, which is a cylinder of insulated copper segments ... In an AC servomotor, the rotor is a permanent magnet while the stator is equipped with 3-phase windings. The speed of the rotor is equal to the rotational frequency of the magnetic field of the stator, which is regulated by the frequency ...
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.

www.egr.msu.edugenerators are: carbon brushes, slip-rings, rotor and stator. The rotor is an electromagnet made by coiling wires around two or more poles of metal core. The stator is a pair of plates attached to the axle. The brushes are connected to the source of energy and work with the commutator in order to let the induced current flow around the system.
