Unipolar electric motor

Conductive disk in a magnetic field.

A unipolar electric motor is a type of electric DC machines . It contains a conductive disk, a constant magnetic field parallel to the axis of rotation of the disk, the 1st current collector on the axis of the disk and the 2nd current collector at the edge of the disk.

The first unipolar motor, the Barlow wheel, was created by Peter Barlow , describing it in the book “The Study of Magnetic Attractions,” published in 1824 .

The Barlow wheel was two copper gears located on the same axis. As a result of the interaction of the current passing through the wheels with the magnetic field of permanent magnets, the wheels rotate.
Barlow found out that when changing contacts or the position of the magnetic poles, the direction of rotation of the wheels changes.
