Simple Electric Motor

The Simple Electric Motor is used to demonstrate the parts and working principle of electric motors.

It consists of the inductor, the inductance and the brass bipolar collector with the brushes.

The necessary magnetic field is created by a permanent, strong linear magnet placed on the top of the device. The device is fixed on a suitable base, which also has the terminals (terminals) for power supply.

In order to operate it requires a voltage of 6-10V DC.

To start the rotation, the electromagnet is placed with its axis in a vertical position, in order to create the necessary torque between its magnetic field and the field of the permanent magnet.

Changing the direction of rotation of the motor is achieved either by changing the polarity of the power supply, through an inverter switch, or by swapping the poles of the magnet.

For smooth engine operation, the collector and brushes should be in good contact with each other and cleaned frequently with fine sandpaper
