LOPE

Single-phase motors,or motors. The single-phase squirrel-cage induction motor is the most widely used form of machine but suffers from the disadvantage, noted in chapter 1, that it produces no starting torque. In order to produce starting torque, a second stator winding will normally be introduced so that, during the s

The d.c. machine,ted on salient poles on the stator and the armature winding is wound in slots on a cylindrical rotor. The frequency of the e.m.f. generated in the armature depends directly on the mechanical speed of rotation, and the action of the commutator is that of a frequency changer so that the frequency at t

Semiconductor control of motors,widely used for the control of speed of both d.c. and a.c. motors. In the particular case of the d.c. machine, variation of the magnitude of the voltage applied to the armature and, in some cases, the field of the motor is required. When considering the control of the speed of an a.c. motor, variati
