Title:
COMMUTATOR AND METHOD OF COMMUTATING CURRENT IN A ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO2006013452
Kind Code:
A8
Abstract:
A commutator for rotation with or by the shaft of a electrical machine has first and second electrically conductive commutator segments (7,8) provided on a base (1) for electrical engagement with brushes (19,20,21) connected to windings, first and second freewheeling segments (9,10) electrically isolated from and interposed between the commutator segments (fig 3), a first diode (23) connected between the first commutator segment and the first freewheeling diode, a second diode (24) between the second commutator segment and the second freewheeling diode, the diodes allow one directional Current to suppress commutation sparking.
