| 20110192087 | PULSE SIGNAL GENERATING APPARATUS, ROTATING MACHINE, CONTROL APPARATUS, AND POWER WINDOW CONTROL APPARATUS - A magnetic path is formed, in response to the rotation of a motor, by a magnetic detector ( | 08-11-2011 |
| 20110018380 | DC MOTOR - A DC motor | 01-27-2011 |
| 20110006628 | MOTOR WITH CASE LID FIXING STRUCTURE - The present invention enables firm fixation between a motor casing and a casing lid at low cost through employment of a simple structure without need to use adhesive. A casing lid made of resin is fixedly fitted to an opening portion of a motor casing made of metal. Grooves or depressions are provided at the bottoms of a plurality of fixation portions provided on the casing lid at constant intervals in the circumference direction thereof. Bend portions at the opening portion of the motor casing are caused to bite into the grooves or depressions of the casing lid fitted into the opening portion of the motor casing, whereby the motor casing and the casing lid are fixed together. | 01-13-2011 |
| 20100320854 | MOTOR - A motor includes a tubular housing having flat side walls along each side of rectangular joined with each other by joining sections, a magnet, having magnet poles in the jointing section, disposed along the inner peripheral surfaces of the housing, a shaft inserted along the axis of the housing, an armature fixed to the shaft in such a position as to be opposite to the magnet, a commutator mounted on the shaft, a carbon brush in sliding contact with the outer peripheral surface of the commutator, and electrical components provided within the housing. The electrical components in the longer direction are arranged nonparallely with all the sides of the housing. | 12-23-2010 |
| 20100001719 | SENSOR MAGNET HOLDER FOR USE IN MOTOR AND ITS MANUFACTURING PROCESS - A sensor magnet holder is mounted on a motor shaft, and a sensor magnet is provided relative to a magnetic induction sensor on the non-moving side for obtaining a signal indicative of a rotational position of the motor shaft. The sensor magnet holder integrally forms a cylindrical portion, a flange portion of a terminal end of the cylindrical portion having a large diameter, a magnet rear end holding portion of the other terminal end of the cylindrical portion and a plurality of snap fit board portions. A shaft press fit portion is formed on an internal diameter of the flange portion. The plural snap fit board portions extend from the cylindrical portion in an axial direction of the motor shaft. A magnet front end holding portion is formed at an extending tip over an outer diameter surface of each of the snap fit board portions. Each of the flexible snap fit board portions snuggly contacts the inner flat surface of the sensor magnet while the sensor magnet is held between said magnet rear end holding portion and said magnet front end holding portion. | 01-07-2010 |
| 20090162038 | MOTOR CHARACTERISTICS ACQUIRING APPARATUS, CONTROL APPARATUS USING THE ACQUIRED MOTOR CHARACTERISTICS, AND POWER WINDOW CONTROL APPARATUS - The rotation period of a motor is subdivided by edge interval times and a rate of change between a currently calculated edge interval time and an edge interval time calculated one rotation of the motor previously is calculated at the detection of each edge. Then the rotation period of the motor is calculated by multiplying a set reference period by the calculated rate of change. | 06-25-2009 |
