A DC motor is a machine that converts chemical or electrical energy into mechanical energy by making the rotors rotate either clockwise or anti-clockwise. The direction of rotation usually depends on the polarity they’re connected in.
Components
A DC motor majorly has 3 components on the outside:-
1. A rotor which rotates when power is supplied to the motor.
2. Connecting wires.
3. A motor body enclosing the functional parts of the motor.
How to use
To use a motor, take its connecting wires and connect them to the terminals of a battery. That’s all you need to do. If the connections are proper, the motor should start rotating. To rotate the motor in the opposite direction, just reverse the polarity of the battery connections.
Common Applications
A Dc motor is used in a lot of appliances such as fans, cars, drill machines, rotary tools, motor pumps, etc. A DC motor, as suggested through its name, functions on DC voltage.
