What is hunting in synchronous motor? The phenomenon of oscillation of the rotor about its final equilibrium position is called […]

How to start synchronous motor? A synchronous motor cannot start by itself, because of the inertia of the rotor. This […]

The stator and the rotor are the two main parts of construction of synchronous motor. The stator becomes stationary, and […]

The working principle of a synchronous motor is based on the principle of magnetic locking between stator and rotor poles. […]

When we apply a three-phase supply to a three-phase distributed winding of a rotating machine, a rotating magnetic field is […]

Commutation in DC machine is generally a current reversal process during which some coils in a machine gets short circuited […]

In a DC machine, two kinds of magnetic fluxes are present; ‘armature flux’ and ‘main field flux’. The effect of […]

The most commonly used method for starting of a three-phase induction motor is the star-delta method. This method of starting […]

A three phase induction motor is basically a constant speed motor so it’s somewhat difficult to control its speed. The […]

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation […]
