Abstract
A polyphase motor apparatus comprises a rotor having a rotating shaft and a plurality of permanent magnets connected therearound, a stator for holding the rotor rotatably and provided so as to surround the rotor, having n phases (n is an integer which is three or more) and n×m (m is an integer which is one or more) magnetic poles, in which each of n pairs of the magnetic poles adjacent to each other is wound with a core wire an end of which is connected to a common terminal (+E), such that one magnetic pole is a first magnetic polarity and the other magnetic pole is a second magnetic polarity different from the first magnetic polarity, and the n-phase voltage from outside is applied between the common terminal and the other end of the core wire of each pair so as to generate a magnetic field for rotating the rotor.
