摘要： In a brushless motor which includes a stator (26) and a rotor (1) rotatably supported inside the stator and wherein the rotor has a yoke (2) formed by laminating a large number of steel sheets (4), the yoke has an even number of magnetic poles (5) protruding outward, and a permanent magnet (3) for a field is inserted into each, or every other, magnetic poles, the permanent magnet rotor of the present invention has a structure in which the permanent magnet for the field is inserted into a slot (6) formed in the magnetic pole, and protuberances (9) striking the side surfaces of the permanent magnet for the field are disposed at the right and left end portions of the slot. Further, in the present invention, in the brushless motor of this kind, engagement pawls (12) engaging with the permanent magnet for the field are so disposed as to protrude, reliefs (13) for absorbing a bend of the engagement pawl are formed in those of the steel sheets laminated to form the yoke which correspond to the engagement pawl. The steel sheets of the yoke are deviated on one or both ends sequentially in the rotating direction. A bridge width at both ends of the slot is set to be greater than the greater one of a width capable of being punched out and a width allowed from a mechanical strength due to a centrifugal force between the width capable of being punched out, a width allowed from the number of passing magnetic fluxes and the width allowed from the mechanical strength due to the centrifugal force. Further, at least one connecting portion of gap is provided to each magnetic pole so as to laminate the steel sheets. The bridge width at both end of the slot is set to be smaller than a width from the outside portion of the permanent magnet for the field to the outside edge of the magnetic pole.

摘要： A brushless motor which includes a stator (9) and a rotor (8) rotatably supported inside the stator. The rotor has a rotor yoke (10) formed by laminating a large number of steel plates, the rotor yoke has an even number of magnetic pole portions (8a) protruding outward, and a field magnet (11) is fitted to each of the magnetic pole portions or every other magnetic pole portions. A magnetic sensor (16) is disposed within the range in which the sensor (16) can directly detect a magnetic flux leaking outside from an end face (8b) of the rotor (8) and is less affected by irregular fluxes near the rotor end face (8b), so that this sensor can detect a peak point of a flux density around the rotor. A magnetic sensor is disposed within the range where the influences of the irregular fluxes are small. A magnet (17) to be detected is fitted to the rotor end face (8b), and a magnetic sensor (16X) for one direction and a magnetic sensor (16Y) for the other direction are disposed near the trajectory of rotation of the magnet to be detected, and these sensors are disposed in the opposite direction to the rotating direction of the rotor in the arrangement such that they are deviated from one another by predetermined angles.
