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： To obtain a power conversion device in which a board to be mounted is downsized by downsizing of elements or an arrangement configuration of the elements, a motor including the same, an air conditioner having the motor incorporated therein, and a ventilation fan having the motor incorporated therein. Included are a printed circuit board 1, whose mounting surface is opposite to an annular surface formed by an annular stator 3 that constitutes a motor 61, arranged to be separated from the annular surface with a predetermined distance, and mounted with a Hall element 6 that detects a rotation position of a rotor 16 of the motor 61 on a mounting surface on a side of the stator 3; an inverter IC 2 that is mounted on the mounting surface on the side of the stator 3 of the printed circuit board 1 to supply a high-frequency current to the stator 3; and an overheat detection unit 14 that is mounted on the mounting surface on the side of the stator 3 of the printed circuit board 1 and detects an overheated state of the inverter IC 2. When the overheat detection unit 14 detects an overheated state, the inverter IC 2 restricts or stops a current to be supplied to the stator 3.
