Principles Of Design

The geared permanent magnet d.c. starter motor has several significant advantages over the wound-field starter, some of which are discussed. The acceleration performance and the cold cranking are shown to depend on both the battery internal resistance and the motor armature resistance. Typical motor characteristics and principles of design optimization are discussed, and it is shown that a motor of reduced weight and high efficiency is achieved compared with comparative conventional machines.

This paper presented a novel analytical method for calculating magnetic field in the slotted air gap of spoke-type permanent-magnet machines using conformal mapping. Firstly, flux density without slots and complex relative air-gap permeance of slotted air gap are derived from conformal transformation separately. Secondly, they are combined in order to obtain normalized flux density taking account into the slots effect. The finite element (FE) results confirmed the validity of the analytical method for predicting magnetic field and back electromotive force (BEMF) in the slotted air gap of spoke-type permanent-magnet machines. In comparison with FE result, the analytical solution yields higher peak value of cogging torque.
