A control method and a switching circuit for braking an electronically commutated electrical motor, wherein operation is in a phase period (T) of an inverter relative to at lest one winding, sequentially, both in a motoring mode and a generating operating mode using various cycles (t -t , t -t ) beginning with zero, such that the driving and braking torques associated with the cycles (t -t , t -t ) produce a resultant braking moment averaged over the phase period (T).

Method of controlling and switching for braking an electronically commutated electrical motor

A self-starting brushless electric motor having a first motor (stator) with poles arranged in a row, said poles constituting ferromagnetic poles or permanent-magnet poles, a second motor part (rotor) with poles arranged in a row, said poles consisting of ferromagnetic poles or permanent-magnet poles and being arranged opposite the row of poles on the first motor part, wherein the motor part with salient ferromagnetic poles or, if both motor parts have salient ferromagnetic poles, at least one of the motor parts has a permanent-magnet pole, and also a magnetizing winding on the first motor part. The system of poles formed by the pole rows is magnetically asymmetrical in the direction in which the motor parts are movable in relation to each other.

Self-starting electric brushless motor having permanent magnet and reluctance poles

A self-starting brushless electric motor having a first motor part (stator) (,) with poles arranged in a row, the poles constituting ferromagnetic poles (,S) or permanent-magnet poles (,A), a second motor part (rotor) (,) with poles arranged in a row, the poles having ferromagnetic poles (,A) or permanent-magnet poles and being arranged opposite the row of poles on the first motor part (,), wherein the motor part with salient ferromagnetic poles or, if both motor parts have salient ferromagnetic poles, at least one of the motor parts has a permanent-magnet pole, and also a magnetizing winding on the first motor part. The system of poles formed by the pole rows is magnetically asymmetrical in the direction in which the motor parts (,) are movable in relation to each other.
