BRUSHLESS MOTOR, AIR COMPRESSOR WITH BRUSHLESS MOTOR, AND ELECTRIC POWER TOOL WITH BRUSHLESS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a brushless motor which connects a neutral point electrically while avoiding complicated wiring.;SOLUTION: A brushless motor 5 comprises an annular core 14 having plural tooth parts, a plurality of coils 16 formed by winding plural conductor wires round the plural tooth parts, and an insulator 13 abutting on one end side in an axial direction of the annular core. The plurality of coils 16 have wires connected by a parallel type multiphase star connection consisting of three phases or more. The parallel type multiphase star connection consisting of three phases or more has a plurality of neutral points electrically connecting the conductor wires of the coils in respective phases, while the insulator 13 has a plurality of terminals 19 which provide the plurality of neutral points, the plurality of terminals 19 being electrically connected by connection conductor wires.;COPYRIGHT: (C)2013,JPO&INPIT
