Direct Torque Control Of Induction Motor PowerPoint PPT Presentations

Compiled by Prof Mitali Ray * Induction Motor (Asynchronous Motor) * Analysis of Induction Machines For simplicity, let assume Is=I1 , IR=I2 (s=stator, R=rotor .

Bearings, mounted on the shaft, support the rotor and allow it to turn. . The rotor current interacts with the flux F, producing torque. .

This project is designed to control the speed of a single-phase induction motor by using operating knob, which is commonly used in home automation applications. The main advantage of these motors is their ability to operate from a single-phase power supply

Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor, the rotor (rotating part) spins inside the stator(static part); in a linear motor, the stator is unwrapped and laid out flat and the "rotor" moves past it in a straight line. Linear motors often use superconducting magnets, which are cooled to low temperatures to reduce power consumption
