Abstract
PURPOSE:To contrive to miniaturize as well as to increase the productivity for subject device by a method wherein, using an enamelled substrate, a Hall element is installed at the place located between the pole piece where magnetic force is transmitted from a magnet and an enamelled substrate, and the enamelled substrate is additionally used as a magnetic path plate. CONSTITUTION:The control circuit 50 having the enamelled substrate is installed on the holder 8 provided at the outer end of the motor. On the holder 8, the pole piece 15 to be used to transfer the magnetic force of the magnet 2 is press-fitted and fixed, while a Hall element 54 is arranged at the place sandwiched from axial direction located between the pole piece 15 and the enamelled substrate 70 and the Hall element 54 is soldered on the enamelled substrate 70. Through these procedures, a magnetic path is formed in a rotating magnetic field with the magnet 2, pole piece 15 and the loop of the steel 71 of the enamelled substrate and this enables to unnecessitate the magnetic path plate to be used for the Hall element, to miniaturize and increase the productivity for the device.
