Self-synchronous electrical motor

摘要

A self-synchronous electrical motor comprises one rotor, one stator formed by at least one set of four stator windings, at least one electronic switch connected to a stator winding to control the current in the stator winding and a sensor of the angular position of the rotor to control the working of the switch. It also has a rotating commutator device, driven by the rotor, to shunt a current coming from a power supply source into windings selected as a function of the position of the rotor. The commutator device is connected to a first end of each of the windings, the second end of two of the windings being connected to the power supply source and the second end of the other two windings being connected to the electronic switch. Application notably to electrical traction systems for automobiles.
