摘要： A method for controlling an electric motor with a softstarter. A softstarter device for control of electric motors. Motor torque is controlled in dependence of a torque error signal, based on a calculated difference between the motor torque and a reference torque value, so that the motor torque displays a rate of change with respect to time, during a stopping or starting time interval, that is adapted to follow a rate of change of the reference torque value, with respect to time, that varies between at least a first part of the time interval and a second part of the time interval, and thereby changing the speed of the motor. A system includes an electric motor, a device driven by the electric motor and a softstarter device for controlling the electric motor. A computer program product includes a computer readable medium and a computer program recorded thereon.
