<P>PROBLEM TO BE SOLVED: To provide a brushless motor capable of suppressing the generation of torque ripple, while eliminating a bus bar to achieve downsizing and cost reduction. <P>SOLUTION: A motor which is configured as a brushless motor of a 10-pole/12-slot type includes six ring connection coils 32 that are arranged in a ring state such that two winding directions adjacent in a circumferential direction are different to each other as six of twelve motor coils 17 of the motor. Further, the motor includes six star-shaped connection coils 35 arranged between each ring connection coil 32 as remaining six motor coils 17 by connecting one end (connection end 35a) to six connection lines 31 that connects between each of the ring connection coils 32 such that two winding directions adjacent in the circumferential direction are different to each other. Then, three-phase driving voltage is applied to the other end (free end 35b) of each star-shaped connection coil 35 by using three terminals adjacent in the circumferential direction as a set. <P>COPYRIGHT: (C)2012,JPO&INPIT |
