ABSTRACT:
The invention relates to a method to optimize the efficiency of a motor operated under a load having an essentially quadratic characteristic curve, the motor being connected to a motor control with whose aid at least one free motor parameter w can be changed to influence the efficiency.According to the invention, the rotational speed n and the input power PEare determined and the motor parameter w is adjusted to a value at which the value E representing the quotient of the cube of the rotational speed n and the input power PEattains a maximum.
