Working Principle of DC Motor

Feb 10, 2019There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are seldom used in ordinary applications because all Get price

An Introduction to Brushless DC Motors

A brushless DC motor is essentially flipped inside out, eliminating the need for brushes to flip the electromagnetic field. In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then charges the electromagnets in the stator to rotate the rotor a full 360-degrees. Get price

Commutation techniques for three phase brushless DC motors

Apr 14, 2017Today I would like to discuss various commutation methods for 3-phase BLDC motors. In a 3-phase BLDC motor system, there are 3/2 H-bridges used to control the current being delivered to the phases of the motor. There are 6 different commutation cycles per electrical cycle to move the rotor between 2 poles. For a 4-pole motor Get price
