ABSTRACT:
A motor is provided, which includes: a rotor having rotor pole groups, in which N-poles and S-poles are alternately arranged in the circumferential direction; an N number (N is a positive integer) of stator pole groups, in which a plurality of stator poles are arranged for individual phases along or in the vicinity of the respective circumferences so as to be positioned at substantially the same rotational phase position in terms of electrical angle; and an (N−1) number of loop windings axially arranged between the stator pole groups, with the same phase being arranged at axial ends, wherein each of the loop windings is arranged radially inner than the outer diameter of each rotor pole group. This simplified winding structure can enhance productivity, reduce size, enhance efficiency and reduce cost.
