摘要
The motor has a rotor (2) and a stator that is provided with a single tooth stator winding, which has a set of phase windings. The rotor includes a set of recesses (4), into which permanent magnets (5) are embedded. An outer contour of the rotor turned to the stator is formed such that an induced electromagnetic force trapezoidally runs into the stator winding and a maximum value of the electromagnetic force continuously lies in an electrical angle ranges from 30 to 90 degrees. The magnets are enclosed by a rotor material, where radially arranged bars (9) are provided between the magnets.
