Abstract

PURPOSE:To offer a motor having small torque ripples by providing respective concentrated winding, driving coil in each phase within an area of a pole pitch of a magnet. CONSTITUTION:A disk 4 faces a disk shaped substrate 1 comprising a magnetic material and is rotatably supported. A ring shaped permanent magnet 5, on which a plurality of poles are magnetized, is provided on the disk 4. On the disk shaped substrate 1, magnetism sensitive elements HA and HB, series connected A phase driving coils W1A-W4A, and series connected B phase driving coil W1B-W4B are provided. Each coil of the driving coils W1A-W4B is located within the area of a pole pitch Pm of the magnet 5. In this constitution, when two phase driving pulse currents are supplied to the A phase and B phase driving coils, torques having opposite phases to each other but analogous waveforms are generated in the driving coils of each phase, and the torque ripples are not generated in resultant torque.
