摘要: In a stator, each bridge of each inner core sheet includes a thin wall portion, which extends in a circumferential direction of the stator and has a smaller axial thickness in a direction parallel to the axial direction of the stator in comparison to the rest of the inner core sheet. A circumferential angular extent of at least one of the thin wall portions of the bridges differs from that of at least another one of the thin wall portions of the bridges in each inner core sheet.

摘要: A stator includes two yokes and two coils. Each yoke is a claw pole type and has a plurality of pole teeth, which extend in an axial direction. The yokes are axially opposed to each other in such a manner that the pole teeth of one of the yokes and the pole teeth of the other one of the yokes are alternately arranged in a circumferential direction. The coils are circumferentially wound to form two phases, respectively, and are arranged between the yokes. A rotor includes a plurality of rotor magnets, each of which provides a magnetic pole. A single magnetic position sensor senses a rotational position of the rotor and outputs a position measurement signal, which indicates the sensed rotational position of the rotor. A half-wave electric current is alternately supplied to the coils based on the position measurement signal.

摘要: A revolving magnetic field type motor has a rotor and a stator. The rotor has a plurality of permanent magnets. The permanent magnets defines a plurality of rotor magnetic poles. The number of the rotor magnetic poles is “P”. The rotor has a plurality of blocks aligned in the rotor's axial direction. The number of the blocks is “m”. Each block has a set of the rotor permanent magnets. One set of the permanent magnets is offset relative to an adjacent set of the permanent magnets by a predetermined offset angle in the rotor's rotational direction. The stator has a plurality of coils, the coils defining a plurality of stator magnetic poles around the axis of the stator, the number of the stator magnetic poles being “T”. The predetermined offset angle is selected from within a range from about zero degrees/((m−1)×n) to about 22.5 degrees/((m−1)×n). The number of the rotor magnetic poles “P” is 8n (n is an integer equal to or greater than one). The number of the stator magnetic poles “T” is 9n (n is an integer equal to or greater than one). This motor reliably decreases cogging torque.
