A geared electric motor for driving, for example, a window glass or a sunroof lid of the motor vehicle, which is provided with a armature shaft, reduction gears for reducing rotational speed of the armature shaft, an output shaft connected with the final section of the reduction gears through a damper, speed increasing gears connected with the output shaft, a rotor connected with the final section of the speed increasing gears, and a rotation sensor for generating a signal according to rotation of the rotor.

Geared electric motor with rotation sensor

A sunroof controlling device for controlling a sunroof lid in sliding and tilting directions without using a mechanical position switch, which is possible to automatically reset count value of the position counter of the sunroof lid according to an appearance of the error in the count value and comprises first and second switches, an actuator having an electric motor and an output shaft to be connected with the sunroof lid, and a control unit including first and second rotation signal generating means for generating first and second signals in response to rotation of an armature shaft of the electric motor, an output shaft rotation signal generating means and a roof position counting means for counting the signals generated from the first, second and output shaft rotation signal generating means, and the control unit executes an initial mode for resetting count value of the roof position counter when the count value is not a predetermined range.

Sunroof controlling device

A sunroof controlling device for controlling a sunroof lid in sliding and tilting directions without using a mechanical position switch, which comprises and actuator having an electric motor and an output shaft to be connected with the sunroof lid, a switch for generating a command signal, and a control unit including an armature shaft rotation signal generating means, an output shaft rotation signal generating means, and a counting means for counting the signals generated from the armature shaft rotation signal generating means and the output shaft rotation signal generating means, and the control unit starts current supply to the electric motor of the actuator in response to the command signal and interrupts the current supply according to the count value of the counting means.

A wiper control device is provided with a wiper motor rotatable in the forward and reverse directions and a motor control circuit comprising a first and a second relay connected with the wiper motor, a first drive circuit connected to the first relay and a first position detecting circuit in series, a second drive circuit connected to the second relay and a second position detecting circuit in series, a first turning time delaying circuit connected with the second drive circuit in series, and a second turning time delaying circuit connected with the first drive circuit in series.

Wiper control device

A sunroof control circuit for controlling a sunroof lid in a sliding and a tilting mode, which comprises an electric motor, a first and a second motor driving circuit for driving the electric motor in the forward and reverse direction, a position detecting switch provided with a contactor, and an arc-shaped first and a second contact plate disposed on a circle with the same radius, a switch means for generating signals to actuate the sunroof lid in respective directions, a first, a second and a third prohibition circuit for prohibiting or permitting signals to be supplied to the respective motor driving circuits in accordance with the position of the sunroof lid detected through the position detecting switch, and a motor-lock detecting circuit for detecting the motor to be locked and stopping current supply to the motor according to the detection of the motor locking.

Sunroof control circuit

A sunroof motor having a roof lid position detector which comprises a motor part, a roof lid detective disc to be turned as much as an angle in proportion to an amount of movement of a roof lid driven by the motor part, a contact plate having contacts and disposed on the roof lid detective disc, a printed wiring board mounted with a relay to supply or shut off the electric power to the motor part and formed with a motor driving circuit which is provided with board-side contacts to be in contact electrically with the contacts of the contact plate for detecting the roof lid to arrive at the full-opened position, full-closed position and so on, for example.
