摘要： An electric motor rotor is provided that can suppress electrolytic corrosion of a roller bearing without damaging productivity and quality because a resin section for integrally molding a rotor magnet, a shaft, and the like is arranged to extend up to between the shaft and the roller bearing. An electric motor rotor 20 according to the present invention is the electric motor rotor 20 in which a resin magnet for position detection 25 and a shaft 23 are integrally molded by a resin section 24 and a load side roller bearing 21a and a counter load side roller bearing 21b are arranged in the shaft 23. The integration by the resin section 24 is performed such that the resin section 24 is interposed between the shaft 23 and the counter load side roller bearing 21b.

摘要： In a motor driven by a drive circuit such as an inverter, there is a problem that electric current flowing through a bearing causes electric corrosion, which impairs the durability of the bearing. A motor 100 of the invention includes: a stator in which a winding 42 is applied through an insulating part 43 to a stator core 41 formed by laminating a predetermined number of electromagnetic steel plates which have been punched into a predetermined shape; a rotor assembly 20 in which a rotor 20a and bearings 21a and 21b formed by rolling bearings are fitted to a shaft 23; a printed wiring board 45 which is arranged at an end part of the stator in an axial direction and to which a drive circuit is mounted; a bracket 30 imposed to at least the end part of the stator in the axial direction to which the printed wiring board 45 is arranged; and a conductive sheet 60 provided between the printed wiring board 45 and the bracket 30.

摘要： A lead wire wiring component 1 includes a lead wire guide 23 that guides power supply lead wires 8 and sensor lead wires 7 to a lead wire leading component 6. The lead wire leading component 6 includes projection portions 22 that can be assembled to the lead wire guide 23. The projection portions 22 are detached from the lead wire guide 23 for molding such that the lead wire leading component 6 is detached from the lead wire wiring component 1 during the molding.
