<p>A controller for a motor according to the present invention is characterized in being provided with: a converter which rectifies and smoothes an AC power source and outputs a primary circuit DC voltage; an inverter which uses the primary circuit voltage to produce a current for driving a motor; a current detector for detecting armature current flowing in the motor; a position detector which is attached to the motor and detects the motor speed; and a current controller which receives a q-axis current command (Iqr) and uses data from the current detector and data from the position detector to output a signal for driving the inverter and to control the armature current flowing in the motor. The motor controller extracts the best possible performance of the motor, and achieves high speed and high output while maintaining stability.</p> |
