Operating variable output electric motors aims at running electric motor with reduced electronic outlay and aims at providing high resolution and good reliability during operation. Power output is specified as desired value and is adjusted by control- or regulating electronics unit (8), any vibrations of electric motor or of parts joined to motor are measured during operation and measured value is supplied to electronics unit. The power (output) is varied by the electronics unit for reducing vibrations to within a tolerance range around the specified desired value. |
