DC Motor or Direct Current Motor: What is it? (Diagram ...

Mar 23, 2013  Principle of DC Motor. When a current-carrying conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. In other words, when a magnetic field and an electric field interact, a mechanical force is produced. The DC motor or direct current motor works on that principle. This is known as motoring action.

DC motor - Wikipedia

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

DC MACHINES

Direct current machines may be magnetized in two different ways: • They may be magnetized by supplying current to the field winding from a separate D.C. source, such as a battery, etc. This type of excitation is called separate excitation. • They may generate their own magnetizing currents. This type of excitation is called self excitation.

Three-Phase Synchronous Motor Construction Working ...

A three-phase synchronous motor has no starting torque. It has to be brought up to speed or as close to it as possible by some other means so that it can pull itself into synchronism. Once up to speed, the rotor field can be excited with direct current and the rotor is, in effect, then dragged around at the same speed as the three-phase stator ...
