摘要： A method of magnetizing a permanent magnet motor involves inserting a spacer in between multi-layered windings (24Ua and 24Va) wound on a plurality of magnetic pole teeth when magnetizing an unmagnetized magnet (26), and removing the inserted spacer (28A) after finishing the magnetization. The spacer (28A) is also inserted in a space between two stator windings (24Ua, 24Va; 24Ub, 24Vb) wound on two magnetic pole teeth adjacent to each other, a magnet material is magnetized by electrifying the stator windings with a direct current in a state of the spacer (28A) being inserted, a permanent magnet is thus formed, and the spacer (28A) is removed after finishing the magnetization.

摘要： A position detector detects the position of a rotor of a brushless motor. A driving signal generator generates a driving signal at a timing corresponding to the detected position. While the driving signal is received, a driving circuit sequentially ON/OFF-operates switching elements of an inverter circuit. At this time, a rotational speed detector detects a rotational speed of the brushless motor. A rotational speed controller controls the duty of ON/OFF operations of the switching elements, performed by the driving circuit, through a chopper signal generator in accordance with the difference between a detected rotational speed and a designated rotational speed. If the detected rotational speed does not reach the designated rotational speed even when the duty becomes a preset value or more, the rotational speed controller generates a phase shift signal for advancing the phase of the driving signal from that of a driving signal in a normal operation, and supplies it to the driving signal generator. Upon this phase shift operation, in the brushless motor, a magnetic flux effectively acting from the rotor to armature windings is reduced as compared with a magnetic flux in a normal operation. Thus, the rotational speed of the brushless motor can be reliably set to a desired value without decreasing the operation efficiency.
