摘要： A method is for starting a sensorless and brushless direct current motor, the stator windings of which are supplied with power from a multiphase converter circuit. For starting the motor, it is first rotated into a defined starting position in an alignment operation through simultaneous energization of at least two phases. Then in a second phase, an energization state of the stator windings which is in the desired direction of rotation and provides sufficient torque is initiated, whereupon then the additional energization states of the corresponding phases follow cyclically, and the rotor is rotated in synchronization with the applied stator rotational field. The motor may be used in a motor vehicle and supplied with the battery voltage at the input terminals. In an example embodiment, the current supplied in the alignment is adjusted according to the battery voltage, and in addition, it is increased according to a specified waveform. This ensures reliable and rapid rotation without overshooting into the starting position.

摘要： An electronically commutated motor includes a stator carrying a plurality of winding strands and a rotor in which the individual winding strands are controlled via power amplifiers in staggered periods of time, the periods being subdivided into control time and idle time. To reduce the power loss in the power amplifiers and to increase the efficiency in the range of high currents, that the control times are subdivided into an initial time segment and a final time segment. At low motor currents pulsing occurs only in the initial or final time segments in pulse width modulation, while at high currents complete switching through takes place in the initial time segments and additionally in the final time segment for a more or less long period of time or in the final time segments and additionally in the initial time segments for a more or less long period of time.
