SOLENOID CONTROLLER FOR SEWING

摘要

PURPOSE: A solenoid controller for sewing is characterized by controlling duty rate of a driving signal in accordance with driving voltage and varying electric current in a fixed range in accordance with the driving voltage. Therefore, the solenoid controller is capable of getting sufficient torque that drives a solenoid, controlling calorification and improving durability of the solenoid. CONSTITUTION: The solenoid controller for sewing is comprised of: a voltage applying part(100) rectifying input voltage and outputting the driving voltage; a voltage monitoring control part(200) detecting the driving voltage outputted from the voltage applying part and outputting the driving signal having the duty rate conformed to the detected driving voltage; and the solenoid part(300) operated in accordance with the driving signal of the voltage monitoring control part(200).
