PROBLEM TO BE SOLVED: To enable control of torque and speed of a permanent magnet type synchronous motor, without having to use a position senor or a speed sensor. SOLUTION: The controller of a position sensorless permanent magnet type synchronous motor enables torque control and speed control, without the use of the position sensor and speed sensor, and moreover assures accurate and simplified position error calculations for the permanent magnet type synchronous motor. |
