Abstract

To better design permanent-magnet synchronous linear motors for high-precision CNC machine tools, this paper conducts multi-objective genetic optimization on four performance indicators - thrust density, thrust ripple, normal force, and terminal voltage. By constructing optimization functions with practical physical significance to perform weighted aggregation of the optimization parameters, the dimensionality of the optimization objectives is reduced, achieving favorable optimization results. Subsequently, the correlation between several key structural parameters and performance indicators of the motor is analyzed, exploring some underlying patterns for this type of motor.
