摘要： A structure of a rotor used in a synchronous motor employing both of permanent magnets and a stator using concentrated windings is disclosed. Slits (13) provided in a section of a rotor laminated in a direction of a rotary shaft are shaped like an arc or a bow, and the shape protrudes toward an outside rim of rotor (12). Permanent magnets (14) are inserted into slits (13). This structure produces less magnetic salient poles than a conventional rotor, so that a magnetic flux density can be lowered, and an efficient motor with less loss is obtainable.

摘要： A motor and a method for manufacturing thereof use a rotor having permanent magnets and stators. The highest revolving speed of a motor is adjusted by using end plates of different thickness. The end plates are made of a magnetic material and disposed at the end faces of the rotor. The end plates made of a magnetic material provide part of the magnetic flux generated from the permanent magnets with short circuits within the inside of the rotor. The magnetic flux that links with the coil can be adjusted by using end plates of different thickness. Therefore, the highest revolving speed of a motor can be finely adjusted with ease.

摘要： An electric motor is equipped with a rotor having multiple rows of slits arranged along a radial direction. A permanent magnet is buried only in some of the slits, namely the ones closest to the center of the rotor or the innermost slits, to drive the motor using both magnet torque and reluctance torque. This improves the torque output.
