Make: EEI, Model:SL-305, Origin: India

Description

The Wiper Motor Working Model is designed to demonstrate the construction, operation and working principle of an automotive windshield wiper system. The unit consists of a representative windshield or curved demonstration panel, wiper blades and arms, linkage mechanism, 12 V DC wiper motor, control switch, wiring harness and a sturdy supporting frame. When operated, the motor drives the linkage to move the wiper arms across the panel, illustrating the wiping motion used to maintain driver visibility.
