The motor as supplied has a DC armature mounted in brass cone bearings. Both the field magnets and the brushes are adjustable. The armature windings are on plastic coil forms which will not permit the wire to unravel at high speeds. The commutator is designed to prevent short circuiting. This increases brush life and does not endanger the user's power supply. For 1.5 or 3V operation. Dimensions: 15 x 9 cm base, and 10 cm height.
