| Abstract |
Permanent Magnet Synchronous Motor (PMSM)
has been widely used for the electric vehicle, the air compressor
and so on. To use PMSM for the electric vehicle, the volume of
it is very important, and more power and wider speed range are
required. Though the inductance is very important parameter to
realize the wider speed range, the design method of the inductance
decided by the motor mechanical parameters D,L and so on has
not been reported and the relationship between the inductance
and the volume has not been cleared.
In this paper, an optimum and an automatic design method
for PMSM from the only required output characteristics is presented.
This method is possible to obtain all motor mechanical
parameters which realize minimum volume and which satisfy a
maximum torque, speed, power and losses inputted by user.
This paper clarified the relationship between the electrical parameters
and the motor mechanical parameters, and this paper
confirmed the output characteristics of the obtained motor by numerical
simulation and Finite Element Method (FEM). |
