Title: Starting controller of motor
Inventor: UEKI YASUHIRO
IPC: H02P6/18
Filed: 1993-08-26
Abstract: PURPOSE:To drive a motor easily without changing a power supply voltage and coil windinq connection by starting the motor with 120-degree conduction sequence normally and with 180-degree conduction sequence whose average torque is higher than that of 120-degree conduction and whose torque minimum point differs when the motor cannot be driven even if a specific amount of time passes. CONSTITUTION:A motor control part 10 switches SWA and SWB when ON signal is received, controls a drive circuit 20 by a 120-degree drive circuit 16 of a drive sequence circuit 12 for starting a spindle motor 22, and at the same time sets a counter 32. Then, when a position signal generation circuit 24 outputs a position signal, the counter 32 is reset and at the same time the switch SWB is switched, thus shifting to the drive by a 120-degree drive circuit 18 based on the position signal. On the other hand, when the counter 32 is overflown while the position signal is not outputted, the switch SWA is switched for a certain amount of time for driving by a 180-degree drive circuit 14, thus returning to the drive by the 120-degree drive circuit 16.
