摘要： The invention relates to a method and a device for automatically adjusting the commutation angle α of a brushless electric motor, the electric motor being driven by an electronic motor controller based on an open loop control and using a variable commutation angle α. According to the invention, the following steps are performed repeatedly: Measuring the actual rotational speed ω of the electric motor; Comparing the actual rotational speed with a previously ascertained and stored rotational speed ωαold, Increasing the commutation angle α by a given value Δα, should ω>ωαold; or Decreasing the commutation angle α by a given value Δα, should ω
