Variable Reluctance Stepper Motor Working Principle: A Variable Reluctance Stepper Motor Working Principle consists of a single or several stacks of stators and rotors-stators have a common frame and rotors have a common shaft as…

AC Series Motor: A series motor can be run from either dc or ac (single-phase) supply provided that both stator and rotor cores are laminated to limit the iron-loss. Figure 10.43 is the cross-sectional view…

Hybrid Stepper Motor Construction and Working: This is in fact a PM stepper motor with constructional features of toothed and stacked rotor adopted from the variable-reluctance motor. The stator has only one set of winding-excited…

2 Phase 4 Pole Permanent Magnet Stepper Motor: Figure 10.39 shows the phases (stacks) of a 2 Phase 4 Pole Permanent Magnet Stepper Motor. The rotor is made of ferrite or rare-earth material which is…

Four Phase Stepper Motor: Four Phase Stepper Motor - The stepper motor is a special type of synchronous motor which is designed to rotate through a specific angle (called a step) for each electrical pulse…

Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by means of a relatively rugged…

Equivalent Circuit of Single Phase Induction Motor: Equivalent Circuit of Single Phase Induction Motor - The winding unbalance and the fact that both the main and auxiliary windings are fed by the same supply result…

Types of Single Phase Synchronous Motor: There are two types of single phase synchronous motor, namely, Reluctance Motor Hysteresis Motor Construction of Reluctance Motor and Torque Speed Characteristics: The reluctance motor, in general, results wherever…

Shaded Pole Motor Working Principle: Figure 10.17 shows a typical Shaded Pole Motor with a squirrel-cage rotor. A small portion of each pole is covered with a short-circuited, single-turn copper coil called the shading coil.…
