Technical Examples
The invention relates to a method to control an electronically commutated motor in which the motor current is influenced as a function of an operating parameter of the motor. According to the invention, the motor current is adaptively switched as a function of the operating parameter of the motor. This means that the waveform over time of the motor current envelope is changed as a function of the operating parameter in such a way that for a value of the operating parameter below a fixed threshold value, a motor current for minimum noise generation is applied and for a value of the operating parameter above the fixed threshold value, a motor current for maximum efficiency of the motor is applied.
