Title:
METHOD FOR OPERATING A D.C. GENERATOR
Document Type and Number:
WIPO Patent Application WO/2011/039257
Kind Code:
A3
Abstract:
The invention relates to a method for operating a d.c. generator, especially a starter (10) for an internal combustion engine, the armature (46) of the machine being fed by brushes (42) and a commutator (44) from a constant voltage source (30, 31). The patination of the commutation system is monitored by the machine-specific startup current (I) and corrected by changing the operating parameters of the machine. The monitoring of the startup current (I) of the machine is carried out preferably on the basis of the power fade ΔU during the startup in the main current circuit of the machine.
