While mass production of electric motor is called for due to increase in application and demand, it causes discrepancy between
design and product. This can affect the response of a motor. In particular, the tolerance of the shape or the residual flux density in the
permanent magnet significantly affects the back electromotive force (EMF). When the magnitude of the back EMF changes, the
current magnitude is changed to obtain the same torque varies. This consequently affects the loss of the motor, and hence leads to
changes in efficiency. In particular, the changes in efficiency cause thermal problems for the motor such as irreversible
demagnetization of the magnets and dielectric breakdown due to the increase in the temperature of the coils. Thus, despite the
inevitable tolerance, the robust performances should be assure. In this paper, Taguchi robust design is applied to ISG motor by using
the multi-response signal to noise for considering back EMF and coil temperature.
