Abstract
PURPOSE:To obtain a miniature motor excellent in controllability, by providing a motor winding section, with the switching transistor base driving windings of a driving circuit. CONSTITUTION:A stator winding unit 5 consists of four windings 5-1, 5-2, 5-3, 5-4 wound up on the same spool 4. The stator windings 5-1, 5-2 are connected to a power source, and have function as a field winding and the primary winding of a saturable transformer. The windings 5-3, 5-4 are the base driving control windings of switching transistors 12, 13. By such circuitry, self-exciting oscillation is performed. As a result, the saturable transformer can be omitted, and a miniature motor excellent in controllability is realized at a low cost.
