Abstract

PURPOSE:To make a torque ripple small and improve the efficiency of an apparatus by setting the number of Hall element to one and by providing a plural sets of position detecting magnets through distinguishing them from torque- generating field magnets. CONSTITUTION:To constitute a coreless motor, a silicon steel disc 7 to be a magnetic path is stuck on a base 2 and a sector armature coil 6 is stuck on said disc 7. In said coil 6, armature coils 10a-10c are arranged in a magnetic material disc 7 and a cylinder 3 is erected in the base 2 to support a rotating shaft 1 rotatably. The central part of a soft steel disc 4 is fixed to said rotating shaft 1 and an annular field magnet 5 is stuck on the back of said disc 4. The outer periphery of said magnet rotor 5 forms position detecting magnets 8, where two sets of such magnets are provided, and a Hall element is further provided in the intermediate space between adjacent coils 10a, 10c. Thus, a good efficiency can be obtained and a torque ripple can be made small in the same manner as Y-connection.
