Compared with traditional DC motor and asynchronous motor, rare earth permanent magnet synchronous motor has simpler structure, more energy-saving and efficient, and more optimized performance. According to the feasibility analysis results, the Φ90 specification cable extruder system is upgraded based on rare earth permanent magnet synchronous motor. After the evaluation of power-saving and economic benefits, compared with the asynchronous motor extruder system, the transformed permanent magnet synchronous motor extruder system can save 25%~35% power, and the daily power-saving amount is 56.2 CNY. At the same time, it verifies the feasibility of the application of permanent magnet synchronous motor in the cable extruder system, and has great economic benefits.
