Electrical Drive Systems: Each Electrical Drive Systems is different from other Electrical Drive Systems. However, there are some common features associated with all Electrical Drive Systems. To understand them it…
Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Variable Reluctance Stepper Motor: Variable reluctance stepper motor can be of single-stack or multi-stack type. Single Stack Variable Reluctance Motor: A variable reluctance stepper motor has salient pole (or tooth)…
Single Phase Induction Motor Types: Single Phase Induction Motor Types - As far as normal running is concerned, a single winding is sufficient. But all motors must be self start.…
Pole Amplitude Modulation Induction Motor: Pole changing method as already discussed allows a change of speed by a factor 2. In some applications, speed change is required only by a…
Pole Changing of Induction Motor: Pole Changing of Induction Motor - For a given frequency, the synchronous speed is inversely proportional to the number of poles. Synchronous speed, and therefore,…
Types of DC Motor: The commonly used Types of DC Motor are shown in Fig. 5.1. In a separately excited motor, the field and armature voltages can be controlled independent…
Classification of Load Torques: As we know already, the nature of Classification of Load Torques depends on particular application. A low speed hoist is an example of a load where…
