Abstract

The present invention relates to the field of electric drive devices and sleeve bearing VFD motors, such as electric motors and electric generators for industrial applications, and more particularly to a method, an arrangement and a frequency converter for controlling vibration of a sleeve bearing VFD motor. The arrangement of the present invention for controlling vibration of a sleeve bearing VFD motor comprises a frequency converter (11), one or more vibration sensors (17-18, 91) and a sleeve bearing VFD motor (12), said one or more vibration sensors (17-18, 91) comprising one or more vibration sensors (17-18, 91) of said sleeve bearing VFD motor (12), wherein said one or more vibration sensors (17-18, 91) is/are arranged for measuring at least horizontal vibration from said sleeve bearing VFD motor and for producing measured vibration data; and wherein said frequency converter (11) is arranged for generating a control torque and for exerting said control torque on the stator of said sleeve bearing VFD motor (12) for controlling vibration of said sleeve bearing VFD motor (12), said control torque being determined utilizing said measured vibration data.
