Design of non-solenoidal operation of starter motor

Abstract

A novel design and fabrication of the gear reduction starter motor is proposed. In this proposed configuration, the conventional solenoid of the starter motor is eliminated, resulting in a reduction in the starting current required while cranking, and the weight of starter motor is reduced by making it more compact. Failed/dead cranking and the cost of starter motor are also decreased. The function of the solenoid in the starter motor is replaced with a spring-coupled drive mechanism, which makes the function of the starter motor an automatic process. This replacement will affect the state of charge (SoC) and depth of discharge (DoD) of the battery positively, thereby reducing the battery drain and making it last long.
