Abstract

PURPOSE:To facilitate an exciting coil winding work and to obtain an arbitrary operating angle thereat by providing a cylindrical iron core projected with predetermined magnetic pole pieces within a stator in which a cylindrical permanent magnet having magnetic poles on the inner peripheral surface and cylindrical exciting coil are provided in parallel in axial direction. CONSTITUTION:Opposite polarity magnetic poles are alternately formed on the inner peripheral surface such as, for example, the cylindrical permanent magnet 1 magnetized to four polarities and the cylindrical exciting coil 2 are provided in parallel in axial direction within a cylindrical case 3 made of magnetic material, thereby forming a stator, the cylindrical iron core 5 fixed to a rotary shaft 4 is disposed within the exciting coil 2, and magnetic pole pieces 6 are projected to confront the magnetic poles of the same polarity as the permanent magnet 1 at the side end of the magent 1 of the iron core 5, thereby forming a rotor R. When a current of predetermined direction is flowed in the coil 2, the pieces 6 will rotate the rotor R from the stationary position of the rotor R confronting the intermediate between the poles of the magnet 1 toward the direction A or B. When the magnetizing positions of the magnet 1 are suitably selected, arbitrary operating angle can be obtained.
