How dose a Electric Motor Work?Electric Motor DefinitionAn electric motor is a device that converts electrical energy into mechanical energy.Motor Working PrincipleWorking principle of DC Motor mainly depends upon Fleming Left Hand rule. In a basic DC motor, an armature is placed in between magnetic poles. If the armature winding is supplied by an external DC source, current starts flowing through the armature conductors. As the conductors are carrying current inside a magnetic field, they will
