FIELD CONTROL METHOD IN WHICH MAXIMUM TORQUE OF A MOTOR DIMINISHING ACCORDING TO AN ANGULAR VELOCITY INCREASE

摘要

PURPOSE: A field weakening control method is provided so that the driving process of a pump motor of vehicles is unified. The actuating time is established as the constant interval. The motor vibration and noise can be reduced.;CONSTITUTION: A field control method is as follows. After the starting of vehicles hangs, vehicles in advance travels by the fixed speed(S100). The driving among steps, and the CAN(Controller Area Network) communications with the motor operate(S105). The steering angular velocity is measured at(S110). When the steering angular speed in advance corresponds to the fixed angular velocity, the field-weakening control operates(S120).;COPYRIGHT KIPO 2010
