E.M.F Equation of DC Generator

We know that the working principle of dc generator, that when conductors begin to cut the magnetic lines of force and therefore, the e.m.f. induces in the conductors according to the Faraday's Law of Electromagnetic …

Working Principle of a DC Generator

Working Principle of DC Generator :      A simple coil of wire ABCD is mounted on a shaft between two magnetic poles. The two ends of the coil are connected to two slip rings, S 1 , S 2 which are mounted on the same sha…

Losses in Induction motor

The losses in an induction motor can be classified as Constant losses. and, Variable losses Constant Losses :      Constant losses are those which doesn't affect due to variation in load conditions on the motor. The…

Types of Single Phase Induction Motors

Types of Single Phase Induction Motors :      Single-phase induction motors are not self-starting because there is no rotating magnetic field produced. It is not practicable to provide initial rotation to the rotor, manual…
