Abstract：In order to optimize the speed and stability of high-speed electric surgical tools,we designed a permanent magnet brushless DC motor with a speed of 70000 rpm.Firstly,the main components of the motor body,position detection circuit and commu-tation control circuit were structurally selected,and various electromagnetic parameters were calculated;Secondly,the motor model was drawn in Ansys Maxwell electromagnetic simulation software,and steady-state and transient finite states were carried out.Element sim-ulation was used to verify its performance.Finally,the response surface method was used to establish an optimization equation with sta-tor inner diameter,rotor outer diameter,permanent magnet thickness as optimization variables and no-load current as optimization tar-get,analyze and solve it.The results showed that the no-load current of the optimized permanent magnet brushless DC motor was re-duced by 57.8%.This study effectively improves the reliability in the application of high-speed electric surgical tools.
