摘要： A trip-resistant frequency control inverter which prevents an overcurrent and overvoltage by frequency control of a motor. Such arrangement provides for generating an accelerating or decelerating rate from the output from a fuzzy controller, which inputs the difference between limiting values and detected values and their changes. The arrangement also provides at the time of acceleration a control which automatically generates an accelerating rate which maintains the current in the vicinity of the limiting value, and a normal acceleration part which adjusts the set accelerating rate. The arrangement further provides at the time of deceleration a control which automatically generates a decelerating rate which maintains the current and voltage in the vicinity of their limiting values, and a normal deceleration part which adjusts the set decelerating rate. Further, the arrangement provides during a steady state operation a control which automatically determines the accelerating or decelerating rate which maintains the current in the vicinity of the limiting value, and wherein the two control parts for automatic and normal operation are selectable by an operator.

摘要： An inverter corrects an output voltage in accordance with the magnitude of output voltage error due to a dead time and an ON-state voltage drop in power elements so as to energize an AC motor in a manner of single phase alternating current excitation, by calculating an active component of current Iq and a reactive component of current Id from the phase .theta. of an excitation voltage vector and a detected instantaneous current value iu, and by measuring characteristic constants of the motor, including a combined resistance (r.sub.1 +r.sub.2) and a combined leakage inductance (l.sub.1 +l.sub.2), from an excitation voltage command value Vc.sub.1, Id and Iq. The measured values are used as the control constants for a speed sensorless vector control. Further, the resistances r.sub.1, r.sub.2, and a self-inductance L.sub.1, which are control constants, can be obtained based on the component in a primary voltage vector direction of a primary current vector Iq' and the component .pi./2 delayed from the primary voltage vector direction of the primary current vector Id'. In this way, the characteristic constants can be accurately measured without any inverter output voltage sensor.

摘要： A vector control system for a permanent magnet synchronous motor, using a current control equivalent output value, a frequency instruction value, a current detection value, an inference phase error value, and a motor constant, identifies a motor resistance equivalent or a resistance setting error equivalent. Next, the vector control unit, using the identified value, corrects a set value R* equivalent of a voltage instruction calculation unit and a n inference phase error calculation unit.Thereby, a vector control system for a permanent magnet synchronous motor can realize a robust control characteristic for changing of a resistance constant of a motor in a low rotation speed area under position sensor-less control. Further, a vector control system for a permanent magnet synchronous motor can be applied in common in a system performing inexpensive current detection.

摘要： A driving apparatus of a synchronous motor fixes all the switching devices of an inverter at OFF in accordance with a value of an all-OFF control pulse signal outputted by a pulse generator. A motor current keeps flowing through free wheel diodes for a predetermined period even after all the switching devices shift to the OFF state. Therefore, pulse generator changes an induced voltage detection signal to an H (high) level after the passage of the time in which a motor current drops down to zero. A terminal voltage of the motor is taken in to acquire an induced voltage and a rotor position is estimated.

摘要： A voltage detector is connected to a connection terminal connected to one phase of an AC output of an inverter through a diode. A removable charge power supply is connected to said connection terminal and another connection terminal. A charge-power-supply connection judging circuit judges whether the charge power supply is or isn't connected, based on a charge power supply voltage detected by a voltage detector. A mode change control circuit outputs switch signal by the result of said judgment. By receiving this switch signal, the inverter controller switches the operation of the inverter between the Motor Drive mode or the Battery Charge mode. Thereby, a motor drive device detects a connecting status of an external charge power supply and steadily switches the operation of the inverter between the Motor Drive mode or the Battery Charge mode.
