Synchronous Motors

Synchronous motors are like induction motors in that they both have stator windings that produce a rotating magnetic field. Unlike

If two stator windings of unequal impedance are spaced 90 electrical degrees apart and connected in parallel to a single-phase

Induction Motor Previous explanations of the operation of an AC motor dealt with induction motors. The induction motor is the

The torque of an AC induction motor is dependent upon the strength of the interacting rotor and stator fields and

It is virtually impossible for the rotor of an AC induction motor to turn at the same speed as that

AC motors are widely used to drive machinery for a wide variety of applications. To understand how these motors operate,

Because the voltage from an AC generator varies as the output load and power factor change, a voltage regulator circuit

The principles of a three-phase generator are basically the same as that of a single-phase generator, except that there are

As previously discussed, there are two types of AC generators: the stationary field, rotating armature; and the rotating field, stationary

Paralleling AC Generators Most electrical power grids and distribution systems have more than one AC generator operating at one time.
