In recent years,with the increasing demand for large optoelectronic devices,stable and reliable driving methods have gradually become a research hotspot.DC brushed motors,due to their inherent drawbacks such as nonlinear periodic torque fluctuations and electromagnetic interference caused by high currents,are no longer able to meet the increasing demand for equipment volume.As a mature motor technology,permanent magnet synchronous motor has the characteristics of stable operation,high output torque,and high reliability,and has gradually become a preferred solution for driving motors in large optoelectronic equipment.The purpose of this paper is to evaluate the performance of PMSM in large optoelectronic devices to ensure their performance and reliability in high-precision optoelectronic systems.By setting up to simulate the actual working environment,the PMSM is tested using a standardized test process,focusing on the test of its speed step and smoothness.The test results show that the overshoot of the PMSM is less than 15%and the stability time is better than 0.4 s in the process of speed step,and the speed fluctuation in low-speed operation can meet the requirements of equipment.It can be seen that the PMSM shows efficient performance and good reliability in the application of large optoelectronic equipment,and can be used as the preferred solution for the drive unit of large optoelectronic equipment.
