Abstract

PURPOSE:To obtain a high-speed motor whose circuit architecture is simple by slidingly contact a sliding compressor provided in a rotor to a position sensor provided on a stator, securing the sensing of the rotor position, and enlarging the amount of sensing. CONSTITUTION:Two-poles magnetized surface 3 and four-poles magnetized surface 4 are provided on a permanent-magnet rotor 1, and a stator 5, wherein a pair of coils 6 having a specified pattern are formed, is provided so that the stator 5 opposes the magnetized surface of the rotor 1. A position sensor 9 is fixed to the stator 5 so that the sensor is protruded from the surface of the stator 5, and sliding compressors 10 and 10 are provided on the rotors 1 and 1. The sliding compressors 10 and 10 are slid on and compressed to the position sensor 9 by the rotation of the rotors 1 and 1. The resistance value of the position sensor 9 is varied by the compression, the position of the rotors 1 and 1 are sensed, and the coils 6 are energized depending on the position of the rotors 1 and 1.
