Optimization of Starter Motor for Automobile Applications

Abstract

Normally, both brushed dc Motor and brushless dc motor are used as a starter motor in the
automobile application. This paper presents the optimization methodology for brushed PM
dc motors. In this brushed dc motor will be a four pole twenty-five slots based machine. This
model analysis involves the more number of analytical calculations and computation for the
selection of the best model, performance and excellent material characteristics. This method
is considered with the existing commercial dc motors to meet the same performance after
reduction of weight with change of some parameters; for cranes to lift the loads, various
trucks, drill hand tool and automotive application likes car, bike. Optimised DC machine
designs using Ferrite permanent magnets are proposed and provide important size and
weight reductions without losing of its performance. The finalized model and the existing
model was solved using the MAGNET Software by FEA (Finite Element Analysis) to see the
basic performance such as flux density, speed, torque, output power of the existing model.
