摘要： A PMA (Permanent Magnet Assisted) synRM and a method for imposing a magnetic force thereon. Magnets are inserted into outer flux barriers of a plurality of flux barriers formed along the radius of a rotor, and bridges or slim portions are formed on inner flux barriers at positions corresponding to the positions of the magnets so that the magnetic force is imposed on the magnets through coils. Since the number of the flux barriers is sufficiently increased while the amount of the magnets consumed is decreased, the PMA synRM has increased efficiency and reduced production costs.

摘要： The method for initially starting the motor improves the reliability to the start of the motor. In particular, even though the external load is at more than a predetermined level, a rotor located at an arbitrary angle can be aligned to an accurate initial position. Moreover, it can prevent the damage of the motor or the damage of the electronic device where the motor is installed. In order to initially align the rotor of the motor, a position on a stationary coordinate system, to which an alignment current of a rotation magnetic field is applied, is varied.

The sensorless motor drive apparatus includes a unit for determining the presence or absence of a position estimation error of a rotor contained in a motor using a current value applied to the motor and a position estimation angle of the rotor. Therefore, the sensorless motor drive apparatus determines the presence or absence of the position estimation error of the rotor without using a sensor, so that it reduces production costs, prevents the motor from generating a faulty operation, and prevents a compressor including the motor from being damaged.
