Abstract :
The Permanent Magnet (PM) Electrical Spindle Motor is an important component in high speed Computer Numerical Control (CNC) machine tools. This paper provides a process to design a high-performance electrical spindle motor, concerning on the motor torque density and torque ripple. Considering the practical design constraints, the design and optimization are accomplished using 2D-FEA. In order to reduce the torque ripple, several methods, such as step-skewed rotor, slot skewing and auxiliary slot are discussed in this paper [1], and some analysis and comparison of the methods are displayed.
