Method for determining the output current and load torque of a vehicle generator, comprises measurement of speed and excitation current and processing them using stored tables and curves

摘要

The output current and/or load torque of a vehicle generator (9) are determined by measuring the generator speed and excitation current. The generator speed is measured by a dedicated equipment (8) and the generator excitation current by a module (6) within the generator regulator (7). The data obtained is supplied to a processor (10) which produces the output current using stored test tables with compensation for air gap width : An independent claim is also included for equipment to measure generator speed and excitation current.
