A torque command current command converter 5 converts the torque command to a current command. A current control device 4 controls so that actual current is flowed according to the command based on each output from a rotor angle calculating means 7, a rotor angle correcting device 8, and a current detector 10.

摘要： PROBLEM TO BE SOLVED: To attain a smooth start by calculating a rotor angle even during the stop of an elevator with a rotor angle calculating means. SOLUTION: A speed control device 62 is operated in response to the deviation between a speed command ω* and a signal ω and outputs the torque command signal T* of a synchronous motor 51. The torque command signal T* is inputted to a torque command-current command converter 63, and a current command I* is calculated. A start compensation torque arithmetic unit 69 outputs the prescribed start compensation torque command while an unbalance detector 8 detects unbalance at the time of a start. A current control device 65 controls the actual current to flow as instructed based on the rotor angle command θ* and current command from a rotor angle calculating means 671 and the output from a current detector 68, and its output becomes the voltage command of an inverter 66. The rotor angle calculating means 671 calculates the rotor angle which is the relative angle between the armature and rotor of the synchronous motor 51 based on the outputs of a magnetic pole detector 52 and a rotation position detector 53.
