摘要： PROBLEM TO BE SOLVED: To realize a control performance without regulating the mounting accuracy of a position detecting means in the control of a synchronous motor using the position detecting means. SOLUTION: In a method for controlling an electric motor when the position detecting means 5 is not mounted at a proper position to the synchronous motor 1 in a proper accuracy, a deviation arises in position information of the position detecting means 5 incorporated in a controller 11. Then, when the position detecting means 5 is not disposed at the proper position, the method includes a step of forming a control phase θdc by a position estimator 20 by operating the synchronous motor 1 without position sensor, and estimating the phase at output signal timing of the position detecting means 5. The method further includes a step of newly holding the estimated phase by inputting the estimated phase to a position information holder 23, tuning the position information of the position detecting means 5 incorporated in the controller 11, thereafter correcting an output of the position detecting means 5 according to information incorporated in the position information holder 23, and operating the synchronous motor 1.

摘要： PROBLEM TO BE SOLVED: To provide a control method for permanent-magnet synchronous motors wherein protection for a switching element of a PWM inverter can be obtained without fail even when the rotor shaft of a motor is locked up. SOLUTION: The control method is such that a permanent-magnet synchronous motor is driven by a PWM inverter. If the rotor shaft of the permanent-magnet synchronous motor is locked up and a direct current is passed through a specific switching element of an inverter, this lockup is detected at Step 220. When lockup is detected, the carrier frequency of the PWM inverter is reduced at Step 280. Thus, the switching loss in the switching element is reduced; therefore, the amount of heat generated by the switching element can be reduced and it can be protected without reducing the current passed through the switching element.
