Application

An Electric Motor is a machine which converts electric energy into mechanical energy. Its actionis based on the principle that when a current-carrying conductor is placed in a magnetic field. Constructionally, there is no basic dif-ference between a DC Generator and DC Motor. In fact, the same DC Ma-chine can be used interchangeably as agenerator or as a motor. DC Motorsare also like generators.

As said above, the same DC Machine can be used, at leasttheoretically, interchangeably as agenerator or as a motor. Whenoperating as a generator, it is drivenby a mechanical machine and itdevelops voltage which in turnproduces a current flow in anelectric circuit. When operating as a motor, it is supplied by electric current and it develops torque which in turn produces mechanical rotation.

Motors can be constructed in several different physical configurations. In the conventional (also known as inrunner) configuration, the permanent magnets are part of the radially center core. In the outrunner (or external-rotor) configuration, the radial-relationship between the coils and magnets is reversed. The stator coils in the outrunner configuration form the center core of the motor, while the permanent magnets spin within an overhanging rotor which surrounds the core.

Significance Of Back EMF

When the motor is operating then the concept of generator comes into the picture i.e., whenever the flux linking with the conductor changes then there will be an induced emf in the conductor. Here, the flux produced by the poles will be stationary and constant and because of the motor principle, the armature starts rotating.

Because the armature starts rotating the flux produced by the main field will be cut by the armature conductor and therefore there will be an induced emf in the armature conductor according to the generator principle.

We know that the direction of the induced emf produced by the motor is opposite to the applied voltage. But the magnitude of the induced emf will be similar to that of the induced emf of the generator.

Advantages Of DC Motor

1. DC motors are smaller in size.
2. These motors operate on DC supply then they can be used in electronics devices.
3. DC motors are suitable for traction systems for driving heavy loads.
4. DC series motors have will high starting torque.
5. Wide range of speed control.
6. DC motors have quick starting, stopping, reversing, and fast acceleration.
7. DC motors are free from harmonics.
