A model of the simplest form of DC motor, with 3 armatures — 2-pole, 3-pole and 4-pole — wound with enamelled copper wire, and a permanent magnetic field provided by a removable bar magnet. The construction is completely open and all components are readily visible. A disc-type commutator is incorporated, and external connection to the phosphor-bronze brushes is by a pair of 4 mm sockets. The motor operates on 4.5 to 9 V DC.
