摘要： In a DC braking method for stopping an induction motor, torque shock generated by an abrupt change of an output current phase is reduced to a predetermined value or less when a switch-over from a normal control state to a DC braking state. When a switch-over from a normal control state to a DC control state is performed, the generated torque shock is reduced to a predetermined value or less is provided. In this case, an abrupt change of an output voltage phase is inhibited by predictably operating the output voltage phase during the DC braking to control the power converter on the basis of a setup DC braking initiation frequency or a phase advanced until the DC braking is initiated, which is predetermined by a deceleration rate and the setup DC braking initiation frequency and the output voltage phase of a normal control state at the instant that a switch-over to the DC braking state is performed.

摘要： It is possible to control a direct current intermediate voltage to be constant, without using a regenerative resistor and an apparatus for feeding back regenerative energy to a power supply, and thus to stably and continuously drive an alternating current motor even at the time of a power failure. A method of controlling the alternating current motor includes the steps of: allowing a power failure detecting unit provided in a power converter to detect a power failure of an alternating current power source; outputting a deceleration start instruction to the inverter unit; calculating a first reduction rate, on the basis of a detection value and a target value of the direct current intermediate voltage, such that the direct current intermediate voltage is made constant during the deceleration of the alternating current motor; calculating a second reduction rate on the basis of a variation in the direct current intermediate voltage; calculating a torque instruction to allow the alternating current motor to be decelerated for a deceleration time; changing an electromotive torque limit value and a regenerative torque limit value on the basis of the value of the detected direct current intermediate voltage; stopping the deceleration when the direct current intermediate voltage is equal to a voltage before the power failure is detected or it rises during the deceleration; and when the alternating current motor is returned to a normal control mode, storing an output frequency before the power failure is detected.

摘要： A method of measuring a motor constant is provided in a vector control apparatus for an induction motor. A voltage output phase θv is set at a previously set arbitrary phase. Prior to applying a current, a current command is fed to operate the vector control apparatus with a proportional-plus-integral controller being set operative. After conduction for a predetermined time, the gain of the proportional-plus-integral controller is set to zero to maintain an integrated value constant and accordingly fix a voltage command value. In this state, a current command value and a detected current value are measured. This measurement is performed at two levels of current, and a primary resistance value (or a line-to-line resistance value) is derived from the slope.
