EP0031688A3 Electric motor start up control 失效
标题翻译：电动马达启动控制
公开(公告)号：EP0031688A3
公开(公告)日：1981-10-21
申请号：EP80304621
申请日：1980-12-19
申请人： MYSON GROUP LIMITED
发明人： Brown, David Michael , Chabra, Janak Raj

CPC分类号： H02P1/44 , H02P23/20
摘要： Apparatus is disclosed comprising an electric motor (10), a device which is driven by the motor and which imposes the imposed load during a motor start up period, current varying means (22, 36) operative during the motor start up period to reduce the current supplied to the motor, and control means (31, 32, 39, 40) to sense the end of the motor start up period and in response thereto to cut out the load reduction means and to cause the current varying means to cease current reduction. The control means may be responsive to a back EMF generated by the motor and may be electronic or electro-mechanical. The current varying means may comprise a resistor in series with a main winding of the motor or may be a triac. The apparatus has particular application to electric motor driven compressors of refrigerant fluid.
