Abstract
Abstract PURPOSE: To prevent generation of noise and vibration as well as to enhance durability and reliability of an apparatus, by means of a time constant circuit and self- holding circuit provided in the operation control circuit. CONSTITUTION: A time constant circuit 21 and a self-holding circuit 25 are provided in operation control circuit 10, for the purpose of slackening the sharp change of signal VT while in addition, producing a number of revolution setting signal VS to be equalized with signal VT when it is stabilized. This constitution is considered to enable this unit to yield its function of actuating its own power supply self-holding operation as well as to slacken any sharp change of a motor speed used for a compressor or general driving service. Accordingly, it is possible to prevent generation of noise and vibration as well as to enhance durability and reliability of those apparatuses such as a compressor and the like.
