VECTOR CONTROLLER AND MOTOR CONTROLLER USING THE SAME, AIR-CONDITIONER

摘要

The present invention is capable of driving the motor control to limit the motor torque output, the vector control device, and a motor control apparatus using the same, to provide an air conditioner as a challenge. In order to solve this problem, on the basis of the output of the power converter to supply power to the motor for driving, when the relevant output is the output voltage saturation state, the field weakening phase output voltage to the motor that governs the output voltage of the power converter The 180-degree control over the direction of the field with respect to the runner in irritation. Or, in a region that is in a non-linear relationship between the output torque and the q-axis current of the motor, and controls the phase of the output voltage of the field-weakening defining the output voltage of the power converter.
