Polyphase induction motors

In I 888 Nikola Tesla (1856-1943) at Columbus, Ohio, USA, invented the first induction motor which has become the basic prime mover to run the wheels of industry today. Below, for simplicity, we first discuss a polyphase and then a single-phase motor. [Pg.5]

In general, the stator of a synchronous motor is quite similar to the stator of an induction motor. The polyphase current flowing in the stator winding sets up a rotating magnetic field in the same way as the induction motor. [Pg.619]

This polyphase (usually three-phase compared to singlephase) motor is the basic work horse of the process industries for general-purpose applications. Characteristics of polyphase squirrel-cage induction motors are... [Pg.620]

Induction Motors. An induction motor is an alternating-current motor in which a primary winding on one member (usually the stator) is connected to the power source and a polyphase secondary winding or a squirrel-cage secondary winding on the other member (usually the rotor) carries induced current. There are two types ... [Pg.403]

Wound-Rotor Induction Motor. A wound-rotor induction motor is an induction motor in which the secondary circuit consists of a polyphase winding or coils whose terminals are either short circuited or closed through suitable circuits. [Pg.403]
