EE 340 Spring 2011 University of Nevada, Las Vegas

Construction of synchronous machines Two common approaches are used to supply a DC current to the field circuits on the rotating rotor: 1. Supply the DC power from an external DC source to the rotor by means of slip rings and brushes 2. Supply the DC power from a special DC power source mounted directly on the shaft of the machine.

Basic comparison between ac and dc motor.

Sep 22, 2012 · Home » Recent Posts » Electrical Machine » Basic comparison between ac and dc motor. Posted on September 22, 2012 by sirajul The basic construction difference between ac and dc motor is that dc motor has direct conduction current supply to rotor and ac motor has inductive supply to rotor no direct conduct.

Working or Operating Principle of DC Motor Electrical4U

Jul 11, 2019 · The very basic construction of a DC motor contains a current carrying armature, connected to the supply end through commutator segments and brushes. The armature is placed in between north pole and south pole of a permanent or an electromagnet as shown in the diagram above. As soon as we supply direct current in the armature, a mechanical force acts on it due to the

DC Motors University of Rajshahi

DC Motors Although ac motors are used in most of the cases, DC motors have many appliions and used for multipurpose appliions. DC Motor Principle 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

Direct Current Motor Basics DC machines Electrical

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction motor, alternating current (AC) machines largely replaced DC machines in most appliions. However, DC motors still have many uses. DC motor principles. DC motors consist of rotormounted
