A new type of horizontal permanent magnet synchronous dynamic and static piezoelectric spindle was taken as the research object, the design and analysis of electromagnetic and control strategy for the electrospindle motor were carried out. The main dimensions of the motor and the electromagnetic parameters of the rotor and stator were calculated. The finite element simulation for the motor was carried out by using ANSYS Maxwell software. According to the structural characteristics of the motor, the control strategy of sliding mode speed control/feedforward decoupling internal model PI current control was designed. MATLAB/Simulink software was used to build the simulation model of permanent magnet synchronous motor control system, and the simulation analysis was carried out. The simulation results verify the feasibility of the design scheme, and provide reference for the development of the electrospindle motor and its control system.
