DC Machine Construction, Working, Types, EMF Equation

Apr 26, 2019· A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque which rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

4 Types of DC Motors and Their Characteristics

Nov 17, 2019· Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load.

What is a DC Machine? Basic structure & Equivalent circuit

A DC Machine is an electro-mechanical energy conversion device. There are two types of DC machines, one is DC generator and another one is known as the DC motor. The construction of the dc motor and generator is nearly the same. The generator is employed in a very protected way. Hence there is an open construction type.

Classifications of DC machines : (DC Motors and DC

Each DC machine can act as a generator or a motor. Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad categories of dc machines; (i) Separately excited and (ii) Self-excited.

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

Electric DC Motors Direct Current Motor Basics,Types and

A DC motor is an electric motor that runs on direct current power. In an electric motor, the operation is dependent upon simple electromagnetism. A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field, it will encounter a force proportional to the current in the conductor and to the strength of the external magnetic field.
