COMPOUND COMPRESSING EQUIPMENT

Japanese Patent JP3885284

B2

PROBLEM TO BE SOLVED: To simplify structure and detecting part of compressing, equipment and protect a driving system, by breaking transfer of driving force when the detection value of a voltage detector is less than a given voltage and more than a given time, and by stopping voltage impression to an electric motor when the detection value of a current detector is more than a given current.
SOLUTION: The compressing equipment has a voltage detector which detects the voltage excited in an electric motor 100 when a clutch mechanism 304 transfers driving force from an external driving source, and a current detector which detects a current flowing through the electric motor when the clutch mechanism breaks the driving force and a given voltage is impressed on the electric motor. When the absolute value of the detection value of the voltage detector is less than a given voltage and more tan a given time, the clutch mechanism is operated to break transfer of driving force, and when the detection value of a current detector is more than a given current, voltage application to the electric motor is stopped. Thus, the structure is prevented from being complicated and the driving system is protected.
