Linear Induction Motor Working Principle

Linear Induction Motor Working Principle: While the conventional induction motor gives rotary motion, a Linear Induction Motor Working Principle provides translational or linear motion. Hence it is termed linear induction motor. To understand the principle of operation let us examine stator of the rotary induction motor (Fig. 6.66(a)). Let the stator be cut and unrolled […]

Single Phase Induction Motor Types

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. The auxiliary winding is provided to produce finite torque at standstill and is displaced in space with respect to the main winding. Current in second […]

Variable Speed Constant Frequency Generator

Variable Speed Constant Frequency Generator: Variable Speed Constant Frequency Generator (VSCF) involves generation of electrical power at fixed frequency and fixed voltage from a variable speed prime mover coupled to the generator shaft. Wind generator is one such example. Speed of rotor varies with velocity and pressure of the wind, but power delivered to the […]
