SYNCHRONOUS MOTOR CONTROL |
摘要 |
Apparatus and method for controlling a synchronous motor driving a square-law torque load at variable speeds by employing a frequency changer. The armature voltage Va may be controlled so that the ratio Va/N at motor speeds above a predetermined value is greater than Va(100)/N(100), where N(100) is the rated speed of the motor and Va(100) is the armature voltage at that speed. Below a predetermined speed, the armature voltage may be controlled so that the ratio Va/N is less than Va(100)/N(100). |
