Procedure and apparatus for the damping of motor vibrations
摘要
A method and an apparatus for damping the vibrations of an alternating current motor is provided. The motor is supplied from an alternating current source with a supply voltage whose frequency is the basic frequency. Additionally the motor is fed with a second voltage having a frequency equal to the basic frequency multiplied by the quantity 2*m*q-1. In the equation, m is the number of the phases of the motor and q is the number of slots per phase.
