<p>Described herein is a n electronically commutated electric motor (1) comprising a stator (10) and an especially permanent-magnetic rotor (11), a control unit (30) which is effectively connected to the stator and is designed to generate control signals for commutating the stator (10, 12, 14, 16) in such a way that the stator (10, 12, 14, 16) generates a rotating magnetic field to rotate the rotor (11), and at least one rotor position sensor, which is designed to detect a position of the rotor and generate a rotor position signal representing the position of the rotor, wherein the control unit (30) is designed to generate the control signals in accordance with the rotor position signal. In an implementation, the control unit (30) is designed to sample and quantize the rotor position signal (27) and generate a digital predictive rotor position signal (95, 100, 102, 104, 106, 108,110,112).</p> |
