Household device for cleaning items of laundry and method for operating a direct current motor fitted with brushes

摘要

#CMT# #/CMT# The household device comprises a brush-fitted direct current motor (1) for driving a washing drum. A stator is equipped with an excitation medium for generating an excitation field (7), where an armature is equipped with an armature winding (2). The armature winding of the excitation medium is electrically isolated to control the current flow independently of the excitation field. #CMT# : #/CMT# An independent claim is also included for a method for operating a direct current motor fitted with brushes. #CMT#USE : #/CMT# Household device for cleaning items of laundry. #CMT#ADVANTAGE : #/CMT# The armature winding of the excitation medium is electrically isolated to control the current flow independently of the excitation field, and hence ensures improving the operational efficiency of the household device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic circuit diagram of a brush-fitted direct current motor. 1 : Brush-fitted direct current motor 2 : Armature winding 5 : Voltage source 6 : Field winding 7 : Excitation field.
