Title: Brushless dc motor and control of the motor
Inventor: JIYON PII SUKUWAIAAZU
IPC: H02P6/18
Filed: 1987-07-01
Abstract: Control and synchronization of a polyphase, brushless DC motor (M) (used for a hard-disk system) during initial start-up of the motor, is effected by monitoring rotor position using a high-frequency commutation: A short current pulse is applied to each power phase (A,B,C) of the motor, and motor current conducted in response thereto is measured to determine therefrom positional information of the rotor. From such positional information the identity of the appropriate motor phase to which is applied a torque-producing current is determined. Cycles of high-frequency commutation and application of torque-producing current are performed, until the rotational speed of the rotor has attained a predetermined RPM. Motor speed is controlled in synchronized, increasing fashion by continued monitoring of the motor current and back-EMF, until a desired rotational RPM is attained, whereupon torque-producing current is sequentially applied to each motor phase in synchronization with the rotor position by deriving positional information from the disk (34).
