摘要： In a motor having a permanent magnet built in a rotor, a hole for preventing a short-circuit of magnetic flux is disposed so that the hole is adjacent to the outer rim of rotor core, and adjoins to a slit for receiving a permanent magnet as well as the permanent magnet per se. This structure prevents a short-circuit of magnetic flux generated by both ends of the permanent magnet, and the magnetic flux at both ends of the magnet can flow to a stator, thereby contributing to generate torque effectively. As a result, the highly efficient motor with less cogging torque, less vibration and lower noise can be provided.

摘要： A rotor magnet of a three-phase reluctance magnet motor is magnetized by coupling two of the three outer terminals (RS), and feeding a positioning current between the outer terminals RS and a third terminal (T) for positioning the rotor at a magnetizing position with reluctance torque. Then, rotor is kept from moving by holding the shaft of the rotor with the rotor positioned at the magnetized position. Next, the outer terminals RS are separated and magnetizing current is fed between the outer terminals R and S to magnetize the rotor magnet.

摘要： A side plate of an impeller is formed so that the height thereof is lowered gradually from an edge portion of a central opening portion toward a circumferential portion. When the distance from the edge portion of the central opening portion to the circumferential portion, in a direction perpendicular to the output shaft, is taken as L, the distance from the edge portion of the central opening portion to the circumferential portion, in the direction of the output shaft, is taken as H, a point on the side plate away from the edge portion of the central opening portion by 0.1×L in the direction perpendicular to the output shaft is taken as P, and the distance from the edge portion of the central opening portion to the point P in the direction of the output shaft is taken as ΔH, ΔH/H≧0.4 is satisfied. With this configuration, the formation of a vortex flow in the flow channel inside the impeller from the air inlet to the air outlet is reduced, and, thus, air blowing efficiency is improved.
