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.

Working Principle Of DC Motor

Motor works on the principle of Loretz force principle. Whenever a current-carrying conductor placed in a magnetic field then there will be a force produced in the conductor. The two fluxes oppose each other. Here, the field flux is produced by the field winding and the armature flux is produced by the armature winding when the armature is given an electric input.

We know that every current-carrying conductor will produce flux. Therefore, the armature current will also produce flux. The direction of the flux produced by the armature conductor is determined by the right-hand thumb rule and the direction of the armature conductor can be determined.

These two fluxes i.e., armature flux and main field flux will interact with each other by which the net flux will be increased towards one side and which will be minimum on the other side.

The increased flux on one side will be in the shape of an enlarged magnetic field or flux or like a stretched rubber band. Therefore, this will exert a force on the surface of the conductor by which there will be momentum in the conductor.

As the armature is in a cylindrical shape and has a radius, therefore, a force will be created on the surface of the armature which leads to turning or twisting which is called as production of torque.
