With the development of new energy vehicle technology, smart and high efficiency driving motors are needed, now permanent magnet machine is the most suitable type. Mostly the IPM rotor structure is used for it can take full advantage of reluctance torque so as to fulfil weakened flux control, however, the magnet bridge’s shape in rotor lamination will cause remarkable influence to motor’s performance. In this chapter, one Integrated Motor and Generator (IMG) type machine is taken as an example to investigate rotor magnet bridge and its yoke thickness to motor’s performance impact, with the FEM (Finite Element Method) electromagnetic simulation, the reasonable rotor structure was explored, and the final designed EM’s electromechanical performance can satisfy system’s requirement.
