  • Patent number: 7091681
    Abstract: A drive circuit for a brushless DC fan motor for rotating a rotor (permanent magnet) by a rotating magnetic field produced by turning on/off the flow of electric current to field coils by a signal to control terminals of switch elements in which switch sections are each connected in series with the field coils. When connecting capacitors for absorbing a current spike in parallel with the switch sections of the switch elements, resistors are each connected between the field coil and switch section, through which the capacitors are connected in parallel with the switch sections. A discharge current of the capacitors which absorbed a current spike when turning on the switch elements is passed via the resistors, thereby eliminating a current spike.

  • Patent number: 7023161
    Abstract: The present invention is to provide a power regulated window having a window glass to be closed intentionally when some foreign body is pinched by the window glass for security reasons. When a close signal is output to a semiconductor switching element from window regulator switches, the window glass is closed. When some foreign body such as arm or fingers is pinched by the window glass, a load current of a motor becomes abnormal and the motor rotates reversely to open the window glass in order not to damage the foreign body. Besides this protective function, when the foreign body is pinched by the window glass and a prohibit signal to invalidate the reverse rotation is output, a reversing controller is stopped and the window glass is closed continuously by a bypass switching element.

  • Patent number: 7009352
    Abstract: A current sensing circuit includes; a shunt resistor, on which a motor current is flown; a reference resistor which has a resistance value that is n times the shunt resistor; and a current following circuit. The current following circuit includes: a following current control circuit, which controls the following current and generates a first reference voltage; and a capacitor which generates a second reference voltage indicating an average value of the first reference voltage. A first comparator compares a third reference voltage higher than the first reference voltage with the second reference voltage, and outputs the current limitation control signal. A motor current sensing range expanding circuit expands a motor current sensing range by increasing a ratio of the current sensing circuit having the shunt resistor and the reference resistor.

  • Publication number: 20040227483
    Abstract: When an operation of lowering window glass is conducted to attain a full-opened state and a lock current flows, a lowering operation is invalidated, thereby preventing the lock current from continuously flowing. When a raising operation is conducted under the full-opened state, a power window motor is operated in a direction of closing the window glass, and the in validating state is canceled. In the case where, before the full-closed state is attained, a foreign object is caught and the lock current flows, the same as above is conducted. In a raising operation of closing the window glass, the raising operation under the full-closed state is invalidated, thereby preventing the lock current from continuously flowing. When a lowering operation is conducted under the full-closed state, the power window motor is operated in the direction of opening the window glass, and the invalidating state is canceled.
