摘要： A variable-flux motor drive system including a permanent-magnet motor including a permanent magnet, an inverter to drive the permanent-magnet motor, and a magnetize device to pass a magnetizing current for controlling flux of the permanent magnet. The permanent magnet is a variable magnet whose flux density is variable depending on a magnetizing current from the inverter. The magnetize device passes a magnetizing current that is over a magnetization saturation zone of magnetic material of the variable magnet. This system improves a flux repeatability of the variable magnet and a torque accuracy.

摘要： An electric machine combined with an electronic control unit including a set of onboard maps of a same setpoint parameter on the basis of first and second operating variables of the machine, each of the maps being associated with a different level of a third operating parameter of the electric machine. The maps include ranges of authorized values, and at least one range of extrapolated values. The electronic control unit is configured, for values of the third parameter not associated with one of the onboard maps, to use interpolated values between two authorized values, or between one authorized value and one extrapolated value.

摘要： Solving Means: A field coil current and a stator current are controlled by a controller. The stator current is controlled under vector control and is controlled so that the phase keeps an efficient motor zone. In a case of rated power generation, when the motor speed is low, the phase current and field coil current are increased to reserve the generated power. And, as the speed is increased, the phase current is decreased to reduce the copper loss, while in place of decreasing the phase current, the field coil current is kept high to reserve the generated power. Thereafter, as the speed is increased more, the field coil current is decreased to reduce the iron loss, while in place of decreasing the field coil current, the phase current is increased to reserve the generated power.
