Electromagnetic Windshield Wiper: Conceptual Study and Analysis

The torque produced by conventional motor used to power conventional wipers may not be enough to move the wipers across the windshield especially during heavy rain.
Higher torque is also needed to clear away snow during winter season. Electromagnetic windshield wiper is an invention that is focusing on replacing the motor as the source of forces / power by using electromagnetic principles. The prototype will make use of rocker- rocker mechanism. The proposed design is very novel because the design mechanism replaces electrical motor with electromagnet, thus reducing the amount of force required while producing higher amount of power. The wipers can be installed on both commercial and passenger vehicles. However, for this paper, it is concentrating on the production of prototype for experimental procedures only. Extensive studies, design modelling, circuit simulation, prototype fabrication and further experiment to analyse the effect of the electromagnetism towards the wiper are conducted throughout the project period.
