Induction Motor Drives Articles: Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular…
Interlocking Components in Electrical Drives: Sensing of signals required for speed and current control loops. Sequencing and interlocking operations are explained in the previous section, whereas this section discusses components…
Measures for Energy Conservation in Electrical Drives: Following Measures for Energy Conservation in Electrical Drives: Use of efficient semiconductor converters. Use of efficient motors. Use of variable speed drives. Energy…
Semiconductor Converter Controlled Drives: These are now widely used both in ac and dc tractions involving dc and ac motors, and the conventional drives have all become outdated, and will…
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…
Drive Circuits for Stepper Motor: A Drive Circuits for Stepper Motor is usually driven from a low voltage dc source. When a phase is to be energised, the dc source…
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)…
Brushless DC Motor Drives(Trapezoidal PMAC): The cross section of a 3-phase 2 pole Brushless DC Motor Drives is shown in Fig. 7.15. It has permanent magnet rotor with wide pole…
