Three-Phase Synchronous Motor | Construction | Working ...

When the motor is rotating at synchronous speed, with a fixed DC excitation in the rotor windings, the rotor flux cuts the stator windings, inducing a voltage in each phase winding. By Lenz’s law, this voltage opposes the applied voltage. The phase relationship between this induced voltage and the applied voltage depends on the relative positions of each stator and rotor pole, which in turn depend on the …

DC motor, how it works? - Magnetic Innovations

A Direct Current (DC) motor is a motor that turns energy from a direct current and turns this into mechanical energy. The first DC motor was developed around the 1830’s-1840s. They were commercially unsuccessful, because these motors were battry powered and batteries were still very expensive and the quality was low.

Working Principle of a DC Motor - Circuit Globe

Before understanding the working of DC motor, first, we have to know about its construction. The armature and stator are the two main parts of the DC motor. The armature is the rotating part, and the stator is their stationary part. The armature coil is connected to the DC supply. The armature coil consists the commutators and brushes. The commutators convert the AC induced in the armature into DC and …

Electric motor - Construction of induction motors | Britannica

Electric motor - Electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
