Abstract

Integrated starter alternator damper (ISAD) system requires motor: high-efficient, high-power density, low-ripple torque. Halbach motor is a new type of PMSM: unique permanent magnet structure makes motor have a sinusoidal magnetic field, can increase magnetic flux density of air gap and decrease magnetic flux density of rotor, which could enhance the power density and efficiency of motor as well as reduce its size. Software of Halbach motor design is given, also with the finite element analysis software with ANSYS language. Experiment proves the advantage of Halbach motor in ISAD system.
