  • Phosphor-Bronze Brushes

All parts of the motor are visible, so students can observe their inner workings. A model of a simple DC electric motor, this device has three armatures: two pole, three pole, and four pole, which are wound with enameled copper wire. A removable bar magnet produces a permanent magnetic field.

A disc-type commentator is incorporated, and a pair of 4 mm sockets provides an external connection to the phosphor-bronze brushes. The motor operates on 4.5—9VDC.
