Title:
COMMUTATOR MOTOR HAVING A NUMBER OF FIELD WINDING GROUPS
Document Type and Number:
WIPO Patent Application WO/2005/109611
Kind Code:
A1
Abstract:
The invention relates to a commutator motor (1), which has a series excitation or shunt excitation and which, in particular, is suited for use as a drive motor for a washing drum of a laundry treatment device. The stator (4) of a commutator motor (1) of this type has a number of field winding groups with field windings (W) that are arranged symmetric to the plane of symmetry of the pair of poles (7) and whose starting points and end points are connected to one another. In order to operate the commutator motor (1) in a number of rotational speed ranges, the field winding groups are individually or jointly activated by a control device.
