Abstract

PURPOSE:To prevent the permanent magnet rotor of a trasistor motor to stop at a dead point of torque by a method wherein stator cores and a plastic magnet having the same shape with the stator cores and magnetized in the 90 deg. electric angle against the stator magnetic axes are laminated. CONSTITUTION:Between stator cores 1, 2 made by laminating steel plates, a plastic magnet 3 having the same shape with the stator cores 1, 2 and magnetized in the 90 deg. electric angle against the stator pole axes X, Y, are arranged and a stator winding 4 is wound around a laminated body of the stator cores 1, 2 and the plastic magnet 3 to form a stator. A cuplike rotor 5 constituted by fixing rotor magnets 6 is arranged with rotation free, and by detecting the position of the rotor-constituting body 5 with a rotor-position detecting sensor 7 current is fed to the stator winding 4. The size of the plastic magnet 3 is so selected as the magnetic absorptivity between the rotor magnets 6 and the plastic magnet 3 becomes to an prescribed magnitude.
