Abstract: Based on the analysis of micro-cutting ultra-high-speed electric spindle built-in permanent magnetic brushless DC motor design features, studied the ultra-high-speed electric spindle permanent magnet brushless DC motor structure and electromagnetic design method. Based on the field-circuit coupling finite element method on the important influencing of the motor performance were analyzed air-gap length and magnetizing method;By using finite element analysis software Ansoft RMxprt module to build motor finite element simulation model, and then imported Maxwell2D on motor no-load and load characteristic simulation analysis. The simulation results show that, high speed permanent magnet brushless DC motor design is reasonable, the motor performance can meet the requirements of the use of electric spindle.
Key words: ultra-high-speed motorized spindle; brushless DC motor; field-circuit coupling finite element method; ansoft; magnetizing method
