Electromagnetic Driven Wiper: Conceptual Study and Analysis

Wipers installed in vehicle is a primary aspect that considerably affects drivers’ visibility. The design of the wiper plays an important role in order to extend and relieve the vision range of the driver. The most reliable industrial wiper is a motor driven mechanism which uses four bar linkage system. This well-known system has been proven as the most reliable system but yet inefficient as the usage of energy is high and consuming a lot of space. This research introduces a new concept of an electromagnetic driven wiper with higher efficiency and low energy required. The power generated by the interaction of the permanent magnet and solenoids will be the main area of study. Furthermore, a study of combination between magnetic fluxes production around magnets (permanent and solenoids) and dipole-dipole moment theory will be used as a main reference in this study. This concept proves that the theory of magnetic flux around a permanent magnet and electromagnets are theoretically the same type of magnetism and relatively comparable to each other. Other than that, the voltage frequency, angles of solenoid and number of loads have been manipulatively varied in order to prove the theory. The concept derivation for the electromagnetic force produced is based on Ampere’s Law and Lorentz’s Law which consider the presence of solenoids and supplies of electrical energy
