Abstract :
This paper deals with the optimal design of surface-mounted permanent magnet motors for use in a high speed spindle machine tool in glass grinding applications. We apply the Taguchi method to refine the stator structure and use segmented rotor magnets for the motor to yield the desired performance. A thermal analysis is conducted to obtain the temperature distribution within the motor. We examine the results using finite element analysis and validate them by experimental measurements.
