20120025746 | MOTOR, ELECTRIC EQUIPMENT, AND METHOD OF MANUFACTURING MOTOR - 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 of the invention includes: a stator in which a winding is applied through an insulating part to a stator core formed by laminating a predetermined number of electromagnetic steel plates which have been punched into a predetermined shape; a rotor assembly in which a rotor and bearings and formed by rolling bearings are fitted to a shaft; a printed wiring board which is arranged at an end part of the stator in an axial direction and to which a drive circuit is mounted; a bracket imposed to at least the end part of the stator in the axial direction to which the printed wiring board is arranged; and a conductive sheet provided between the printed wiring board and the bracket. | 02-02-2012 |
20130175012 | POWER CONVERSION DEVICE, MOTOR INCLUDING THE SAME, AIR CONDITIONER HAVING THE MOTOR INCORPORATED THEREIN, AND VENTILATION FAN HAVING THE MOTOR INCORPORATED THEREIN - A power conversion device includes a printed circuit board, whose mounting surface is opposite to an annular surface formed by an annular stator that constitutes a motor, arranged to be separated from the annular surface with a predetermined distance, and mounted with a Hall element that detects a rotation position of a rotor of the motor on a mounting surface on a side of the stator; an inverter IC that is mounted on the mounting surface on the side of the stator of the printed circuit board to supply a high-frequency current to the stator; and an overheat detection unit that is mounted on the mounting surface on the side of the stator of the printed circuit board and detects an overheated state of the inverter IC. When the overheat detection unit detects an overheated state, the inverter IC restricts or stops a current to be supplied to the stator. | 07-11-2013 |
20130285482 | ROTOR OF ELECTRIC MOTOR, MOLD MOTOR, AIR CONDITIONER, AND METHOD OF MANUFACTURING THE MOLD MOTOR - A rotor resin assembly of a rotor of an electric motor includes a rotor magnet including a substantially cylindrical yoke molded from thermoplastic resin containing a soft magnetic material or ferrite and a resin magnet integrally formed in the outer circumference of the yoke, a position detection magnet arranged at one end in the axial direction of the rotor magnet, and a substantially doughnut-like rotor core arranged in the inner circumference of the rotor magnet and formed by laminating a predetermined number of electromagnetic steel plates. The rotor magnet, the position detection magnet, and the rotor core are integrally formed by resin. A shaft is inserted into an inner diameter section of the rotor core, and the rotor resin assembly is caulked by a jig to form a recess in the vicinity of the inner diameter sections of both end faces of the rotor core and assembled to the shaft. | 10-31-2013 |
20130293036 | MOLD MOTOR AND AIR CONDITIONER - A mold motor includes a mold stator, a rotor, and a bracket. The mold stator includes a first bearing housing section formed of thermosetting resin, one bearing of the rotor fitting in one end in an axial direction of the first bearing housing section, an opening section formed at an end on the opposite side of the bearing housing section, and a bracket press-fitting section formed near the opening section and having a diameter larger than a stator inner diameter. The bracket includes a bracket resin section configuring a second bearing housing section in which the other bearing of the rotor fits and a bracket sheet metal section press-fit into the bracket press-fitting section of the mold stator. In the bracket, the bracket resin section and the bracket sheet metal section are integrally molded. | 11-07-2013 |
