Clearly view the inner workings of this motor through the completely clear construction. This model of a simple DC electric motor features three armatures - 2 pole, 3 pole, and 4 pole - all wound with enameled copper wire. A permanent magnetic field is produced by a removable bar magnet. A disc-type commutotor is incorporated and external connection to the phosphor-bronze brushes is by means of a pair of 4 mm sockets. Operates on 4.5-9 VDC.
