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.
