  • Patent number: 5757150
    Abstract: An electric system of an electric vehicle including a main battery as a power supply, and a semiconductor power converter for driving a wheel driving motor. Impact destroying switches are inserted into connecting lines which connect a main battery to the semiconductor power converter, and into a connecting line connecting main battery block. Each impact destroying switch breaks its conduction by blasting an explosive in the switch in response to the impact due to a collision of the vehicle body. In case of an emergency such as a collision, since the main battery is instantaneously disconnected from the connecting lines by the switches, the connecting lines become free from the voltage. This makes it possible to prevent fire, and to cut off the vehicle body to save passengers.

  • Patent number: 5734216
    Abstract: 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.swhere 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.

  • Patent number: 5656911
    Abstract: 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.

  • Patent number: 5504414
    Abstract: An electric system for an electric vehicle enabling a secondary battery to be charged easily without using a large capacity and bulky charging system. The system can maintain integrity of power on a distribution network during charging. When charging the secondary battery, a switch connecting an inverter to an AC motor is opened, and then, the AC voltage from an external distribution network is supplied to the AC side of the inverter. The inverter rectifies the AC voltage to a DC voltage under the control of a control circuit so that the secondary battery is charged by the DC voltage. In another example, the windings of the AC motor may be connected between the distribution network and the inverter by the switching operation of a three-pole contactor so that the windings function as AC reactors.

  • Patent number: 5466998
    Abstract: 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.
