Brushless direct current-machine e.g. brushless direct current-motor, has electronic commutator including electronically controllable switch elements connected with junctions of homogeneous winding elements in closed progressive winding

摘要

The machine has a stator with an electrical coil, a permanent magnetic-rotor (1), and an electronic commutator including electronically controllable switch elements e.g. p and n-channel-MOSFETs, connected with positive and negative operating bus bars. A closed progressive winding consists of a number of circular homogeneous winding elements that are connected in series and include junctions that are provided between the winding elements. The junctions are characterized such that the junctions are connected with the switch elements of the commutator.
