Title:
CONTROL DEVICE FOR ELECTROMAGNETIC CLUTCH OF GAS COMPRESSION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/230484
Kind Code:
A1
Abstract:
The purpose of the invention is to suppress sudden application of a load on a motive power source that drives an electromagnetic clutch. This control device (200) comprises an electric power supply unit (230), an acceptance unit (210), and a current passage control unit (220). When a signal (S) is input from the acceptance unit (210), the current passage control unit (220) switches, in accordance with the rotation speed E and/or discharge-side pressure (P) of a compressor (100) upon startup, between [1] a first control for applying a relatively high voltage necessary for passing a relatively high current through an electromagnetic coil (93) and [2] a second control for applying a voltage lower than the high voltage in [1] and necessary for passing a current that is lower than the high current in [1] and that is sufficient for coupling an armature (94) to a rotor (92), as the voltage to be applied to the electromagnetic coil (93).
