| Summary: | The article considers an approach to determining the
permissible ranges of changes in the armature voltage,
armature current and the excitation coefficient of the
DC traction motor of a mining dump truck to ensure
satisfactory commutation. When the DC motor is running
in the specified modes, the probability of sparking in
the collector-brush unit with a degree of 2 points will
be minimal. A method for determining the permissible
operating modes of a mining dump truck traction motor to
ensure satisfactory commutation is proposed. The method
allows, based on the analysis of experimental data, to
determine the permissible ranges of changes in voltage,
armature current and excitation coefficient, at which the
degree of sparking does not exceed 1½ points. |
