Abstract
An electrical machine with a stator component and a rotor component, wherein the stator component carries the winding of the electrical machine, which has a number of coils. An electronic power unit is provided to control the electrical machine. To obtain an electrical machine, which has a long service life but does not occupy much space, the stator component has two or more separate windings to form two or more electrical sub-machines. The electrical machine can be used to advantage as a starter-generator in commercial vehicles and busses. An improved electrical system is also described.
Claims26
A starter-generator comprising
- a rotor component,
- a stator component comprising at least two separate windings, each of said windings comprising a plurality of coils and a plurality of linking conductors connecting the coils of the respective winding, thereby forming at least two electrical sub-machines, all of the coils of being arranged in a single ring, the coils of each said winding being arranged in circumferential series with the coils of each other said winding, and
- at least one electronic power unit for controlling said electrical sub-machines.
An electrical system with an on-board network comprising a starter generator, said starter generator comprising
- a stator component comprising at least two separate windings, each of said windings comprising a plurality of coils and a plurality of linking conductors connecting the coils of the respective winding, thereby forming at least two electrical sub-machines, all of the coils being arranged in a single ring, the coils of each said winding being arranged in circumferential series with the coils of each other said winding, and
- at least one electronic power unit for controlling said electrical sub-machines.
