Title: Drive control circuit of electromagnetic drive device
Inventor: IWASAKI SHOJI
IPC: H02P25/06
Filed: 2001-12-12
Abstract: PROBLEM TO BE SOLVED: To provide a drive control circuit of an electromagnetic drive device which can avoid electrical and mechanical damages produced when a power supply is turned on and off and has a long operation life. SOLUTION: This drive control circuit has a drive circuit 41 which applies a current to a drive coil 24 of an electromagnetic drive device 30 according to a drive control signal voltage CS, a voltage detection circuit 43 which detects the power supply voltage of the drive circuit 41, and a drive coil short circuit unit 42 which short-circuits the drive coil 24 and releases the short-circuited state according to the detection output of the voltage detection circuit 43 when the voltage of the power supply (+VCC and -VCC) reaches a prescribed value. If an overcurrent is outputted from the drive circuit 41 when the power supply is turned on, the drive coil short circuit unit 42 keeps the short-circuited state of the drive coil 24 until the power supply voltage reaches the prescribed value to avoid the application of the overcurrent.  When the power supply is turned off, the short-circuited state of the drive coil 24 is kept by the drive coil short circuit unit 42 and a closed circuit is formed, so that a short break state is produced even if an external force is applied to the drive coil 24.
