초록

An electronically commutated motor (4) has a permanent-magnet rotor (28) and has a stator (14) that has two winding phases (25, 26). During one rotor rotation of 360.degree. el., firstly current is delivered to the one winding phase (25) within a first rotation angle range via an associated first semiconductor switch (68); and within a subsequent second rotation angle range, current is delivered to the other winding phase (26) via an associated second semiconductor switch (70). The motor further has a commutation apparatus for alternatingly switching ON ...
