摘要： A LPF extracts DC component of a current detection value of an inverter input current. A subtracting section 4 calculates a difference between a current command value and the DC component of the current detection value. A current controller 5 produces two-phase PWM signals Sa and Sb complementary to each other, from the current difference. Further, an integrating circuit 7 integrates output terminal voltages Vu, Vv and Vw of the inverter to convert the output terminal voltages Vu, Vv and Vw into a magnetic-flux information Φu, Φv and Φw. A logic conversion section 8 converts the magnetic-flux information Φu, Φv and Φw into 120-degree conduction patterns S1′-S6′ to output the 120-degree conduction patterns S1′-S6′. Then, a logic circuit section 9 executes a logic synthesis between the PWM signals Sa and Sb and the 120-degree conduction patterns S1′-S6′ to output gate signals S1-S6.

摘要： Method for operating a delta wound three-phase permanent magnet brushless motor. A transition speed is determined in a quadrant of a speed versus torque curve above which speed continues to increase while current/torque decreases wherein actual phase current can be controlled in a current control modification manner which reduces requested phase current. The modification manner is determined for a quadrant, wherein a controller can use the modification manner to reduce the requested phase current to control the actual phase current when the speed is above the transition speed. The motor is controlled in a quadrant wherein, when the motor has a speed above the transition speed, the controller reduces the requested phase current in the modification manner and the controller supplies the actual phase current to the motor using the reduced requested phase current and using measured phase current of the motor derived from using a single current sense resistor.

摘要： In some embodiments, a system of controlling an induction electric motor, includes a command voltage output unit for generating a command voltage for operating an inverter according to a command speed and outputting the generated command voltage to the inverter; a control unit for controlling the command voltage output unit such that the command voltage output to the inverter is compared with an operation limiting voltage and the command voltage is corrected to fall within the operation limiting voltage; and the inverter for controlling the induction electric motor depending on the corrected command voltage. Thus, it is possible to precisely control the induction electric motor even in a high speed operation region by regulating the magnitude of the command voltage applied to the induction electric motor by means of dynamic modulation strategies without the magnetic flux controller.
