The method involves determining speed of a permanent magnet-rotor, and generating a model-speed value. A current-conducting stator conductor is coupled with a test signal source, and an injection-speed value is generated. The influence of the injection-speed value against the model-speed value is attenuated. The injection-speed value is weighted with factors, and the weighted injection-speed value is combined with the model-speed value in a combination device (50). The combination-result from the combination device is used as the determined drive speed. An independent claim is also included for a device for determining an electrical drive-speed and/or position of a permanent magnet-rotor of an electrical brushless linear or rotational machine. |
