Two-strand electronically commutated motor operating method for actuating ventilator, involves providing output stage for influencing current feed of cable in stator, where DC intermediate circuit with capacitor supplies current to stage

摘要

The method involves providing an output stage (122) for influencing the current feed of a cable in a stator. A DC intermediate circuit (170) with a capacitor (178) supplies current to the output stage. A commutation process is executed for a predetermined commutation time point in the output stage. The commutation time point is determined based on the energetic recovery system in the capacitor. An independent claim is also included for an electro motor comprising a rotor.
