Title:
SOLENOID ACTUATOR DRIVE
Document Type and Number:
Japanese Patent JP3871616
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a solenoid actuator drive with few variations in response.
SOLUTION: This solenoid actuator drive, used for driving a solenoid actuator having an electromagnet wound with a coil outside a hollow portion and a plunger slidably retained on the hollow portion, comprises a coil resistance detecting means, a voltage calculating means, and a voltage supplying means. The coil resistance detecting means detects the resistance value of the coil by passing low current within an inoperative range of the solenoid actuator through the coil at the time of non-driving. The voltage calculating means calculates the voltage supplied to the coil based on the resistance value detected by the coil resistance detecting means. The voltage supplying means supplies a voltage calculated by the voltage calculating means to the coil.
