Patent ID: 8847522

Claim:
A motor comprising: a stationary member provided with, a number M (M is a positive integer) of first poles within 360 electrical degrees at spaces therebetween; a plurality of concentrated, full-pitch windings at least partly wound in the spaces, respectively, in the stationary member; a movable member movably arranged relative to the stationary member and provided with a number K (K is a positive integer) of second poles, the number K of second poles being different from the number M of first poles; and a unidirectional current supply unit that supplies a unidirectional current to at least one of the windings so as to create an attractive force between at least one of the first poles and a corresponding at least one of the second poles to thereby move the movable member relative to the stationary member, wherein the unidirectional current supply unit includes at least two current supply paths, and is configured to supply the unidirectional current simultaneously to at least two of the plurality of windings through the at least two current supply paths, respectively, the at least of the windings being cyclically, in a sequential combination, designated by a control device.
