| Zusammenfassung: | A commutator for rotation with or by the shaft of a electrical machine has first and second electrically conductive commutator segments provided on a base for electrical engagement with brushes connected to windings. Isolated from and interspersed between the commutator segments are first and second freewheeling segments. A first diode is connected between the first commutator segment and the first freewheeling segment. A second diode is connected between the second commutator segment and the second freewheeling segment. The diodes allow current to flow in only one direction between the commutator and freewheeling segments to help suppress commutation sparking. |
