Product InformationA model of a simple DC electric motor, this device has three armatures — two pole, three pole, and four pole — all wound with enameled copper wire. A permanent magnetic field is produced by a removable bar magnet. The construction of the model is completely open, so all parts are clearly visible for students to observe its inner workings. A disc-type commutotor is incorporated and external connection to the phosphor-bronze brushes is through a pair of 4mm sockets. The motor operates on 4.5–9 VDC. Size: 20 x 12.5 x 20cm.
