摘要： An inverter converting by using semiconductor power switching devices a DC voltage supplied from a main battery to an AC voltage supplied to an AC motor. Unipolar switching devices such as MOSFETs are used as the power switching devices. The power switching devices are controlled so that the output voltage of the inverter is composed of pulses taking three levels in the operation range of high output power. This makes it possible to reduce the stationary loss and switching loss of the switching devices, and to increase the efficiency of the inverter.

摘要： A magnet rotor for a synchronous motor includes a yoke formed of a magnetic material. A generally cylindrical permanent magnet is disposed around the yoke magnet and has N and S poles alternately located in the circumferential direction of the permanent magnet.

The adhesive is hardened at a hardening temperature, which is around a maximum temperature encountered during operation of the motor to accomplish bonding between the yoke and the permanent magnet. The clearance between the yoke and the permanent magnet has a dimension L given by the following formula: L.gtoreq.(E.times..DELTA.L) / .sigma.s where E is a tensile elastic modulus of the adhesive; .DELTA.L is a change amount of the clearance upon thermal expansion or contraction; and .sigma.s is a tensile stress applied to the adhesive.

摘要： In an electric system for an electric vehicle, DC power of a main battery is converted into AC power by an inverter which has a power regenerative function. At startup, the system charges an input smoothing capacitor on the DC side of the inverter through an initial charging circuit with an initial charging switch and resistor. A main circuit switch that can stop current is connected between the main battery and the inverter. A rheostatic braking circuit with a rheostatic braking switch and a braking resistor is connected to the DC input side of the inverter for rheostatic breaking when required. Rheostatic braking takes over after regenerative braking when the main battery loses its power absorption capability, with the main circuit switch off. Semiconductors can be used as switches, and can be placed on a cooling body or modularized. Low-noise wires can be used to reduce noise.

摘要： A driving device controls a permanent-magnet synchronous motor having a permanent magnet in its rotor using a voltage-type inverter supplying drive power for the synchronous motor, makes the torque of the synchronous motor and the d-axis current flowing in the synchronous motor in the direction of the magnetic flux generated by the permanent magnet approach their own command values, and performs weakening field control by decreasing the d-axis current. To perform the above described control without complicated d-axis current command value operations or temperature amendments to motor constants, the driving device includes a proportional controller for outputting a d-axis signal proportional to the deviation between a d-axis current detection value and a d-axis current command value for the motor. A d-axis voltage command value and a q-axis voltage command value are determined according to the d-axis signal and a q-axis signal obtained based on the deviation between a q-axis current detection value, which is a component in the direction normal to the magnetic flux, and the torque command value for the motor. A voltage command vector is obtained from the d-axis voltage command value and the q-axis voltage command value. The voltage command vector is PWM-converted and a voltage-type inverter control signal is generated.

摘要： A current transformer (4) detects the output currents of a voltage-type inverter (INV), and comparators (6) check whether the outputs from the current transformer exceed a predetermined limit value. The detected output currents are fed to a vector analyzer (8) to determine the location of the output current vector. A zone determining circuit (9) determines the location of the current vector in the zones. An output pattern generating circuit (10) responds to the output from the zone determining circuit (9) and provides a switching pattern corresponding to the voltage vector nearest to a vector having the direction opposite to that of the output current vector. A selector (2), being controlled by the comparator (6), selects a switching pattern from the output pattern generating circuit and provides it to the inverter (INV), when the comparator (6) detects that the magnitude of the current vector exceeds the predetermined limit value. The rate of change of the output current vector works so as to reduce the current regardless of whether the motor (IM) (a load of the inverter) is to be driven or braked, regardless of the location of the counter-electromotive force vector or the location of the voltage vector selected at that timing when the current limit enters into action. This ensures that the output current of the inverter (INV) will be reduced.
