摘要： A 1-phase coreless disk-type brushless motor or axial-flow brushless fan motor comprises a single position-detecting element located at a position on a printed circuit board corresponding to one of the magnetically active conductor portions of a stator coil or coils of the stator armature. A cogging-generating stator yoke having a cutaway portion of a specifically determined angular width is positioned relative to the stator coils, such that an end of the cutaway portion thereof is spaced by a distance equal to about one fourth of the pole width from another magnetically active conductor portion of the stator coils, so that the magnet rotor may stop at a position from which the motor can start itself. Various forms of such cogging generating stator yoke are disclosed, including a stator yoke which also serves as a circuit board.

摘要： A 1-phase brushless motor comprises a single position-detecting element located at a stationary position corresponding to a magnetically active conductor portion of an armature coil of an armature member. The position-detecting element is either a magnetoelectric transducer or a position-detecting coil. A plastics magnet is molded integrally with the armature coil and is magnetized such that it cooperates with a field magnet as a rotor to generate a field magnet attracting and repulsing torque within a particular range from a dead point, so as to stop the field magnet at a position from which the motor can start itself.

摘要： For driving a direct-current motor in tune with the frequency of an external synchronizing signal regardless of any abrupt change in the load or in the synchronizing signal frequency, a rotor position signal is produced in the form of a succession of pulses in phased relationship to the rotation of the motor. A first control circuit is provided to initiate the supply of electrical energy from a DC power supply to the motor in response to each pulse of the synchronizing signal and to suspend the supply of electrical energy in response to each pulse of the rotor position signal. This first control circuit is combined with second and third control circuits adapted to modify the operation of the first control circuit in event the motor has fallen out of synchronism. Thus, when the actual speed of the motor becomes higher than the required synchronous speed, the second control circuit operates to permit the motor to be fed continuously from the DC power supply, and when the actual motor speed becomes lower than the synchronous speed, the third control circuit operates to prevent the motor from being fed from the DC power supply, until the motor is pulled back into synchronous operation. Several other embodiments are disclosed.
