Abstract

In a method or system for driving a load element, a drive motor is provided on a drive shaft of the load element that establishes a drive rotation speed of the load element. A rotation torque sensor on the drive shaft emits a load torque signal proportional to a rotation torque. A rotation torque influencing device generates a supplementary torque when the load torque signal deviates from a desired load angle value present when a change has not occurred to a load created by the load element and acting on the drive motor, the supplementary torque being added to a drive torque generated by the drive motor such that a load angle of the drive motor remains substantially constant and uninfluenced by a change of the load.
