KRETSANORDNING FOR EN REVERSIBEL ELEKTRISK DRIVMOTOR, SPEC EN VINDRUTETORKARMOTOR |
摘要 |
A windshield wiper system having an electric motor for driving windshield wipers through repeating wiper cycles by reversing the direction of rotation of the motor through a reversing switch comprising a pair of relays which control the polarity of current applied to the motor. A limit switch is mechanically coupled to the motor for detecting the end positions of the motor and for providing signals indicative thereof. First and second time delay circuits each have an output respectively coupled to one of the relays, and each delay circuit has a pair of inputs coupled to the limit switch. Each delay circuit is activated to provide a delayed output to its relay by a respective end position signal which immediately deactivates the other delay circuit. |
