Introduction,s as prime mover due to the following advantages. They can be brought very close to the working machine (load), can be operated at any desired speed through power electronic control, and can be started and reversed in very short periods of time. The electric motors are also available in the market i

Direct Torque Control and Sensor-Less Control of Induction Machine,e space vector. Although by using high switching frequency in a PWM inverter the desired curves of the actuating variable can be sufficiently approximated. However, for high power drives, the switching frequency can not be more than 200-300 Hz due to economic reasons. Thus, in high power drives, it

Switched Reluctance Motor Drives (SRM),ntages are the torque ripple and acoustic noise. Now these disadvantages have been minimized by improving the design, sensorless drives have been developed, and many manufacturers are producing the SRM, making it easily available motor. The switched reluctance motors have many advantages, e.g. high
