Apr 21, 2015· Dc motor 1. Working principle of DC motor 2. DC MOTOR DC motor stands for direct current motor. A machine that converts dc power into mechanical energy is known as dc motor. Its operation is based on the principle that when a current carrying conductor is placed in a magnetic field, the conductor experiences a mechanical force. 3.

Applications of DC Motor [ Series, Shunt & Compound Motor ...

DC Motors: Principle of Operation. Electric motors run by electromagnetism. However, there are also other types of motors that utilize electrostatic forces or piezoelectric effect. In the case of a PMDC {Permanent Magnet DC) motor, motion is produced by an electromagnet (armature) interacting with a fixed field magnet (housing assembly).

Electric motors and generators

Jan 21, 2019· Basic Operation. A DC drive supplies voltage to the motor to operate at a desired speed. The motor draws current from this power source in proportion to the torque (load) applied to the motor shaft. Speed, 0% Load. In this example an unloaded motor connected to a DC drive is being operated at speed.
