Alternating current contactor control structure and control method

The invention discloses an alternating current contactor control structure and control method. Electromagnetic coupling of an alternating current contactor in the prior art is changed into mechanicaltransmission coupling. The combination of a stepping motor, a matched screw hollow shaft, a solid shaft and a movable rod is used to replace a silicon steel sheet and a copper winding. The problems ofoverheating and over-high noise of a long-term charged coil of an original alternating current contactor control method are avoided. The stability, safety and energy consumption are greatly improved.The structure is free of electromagnetic coupling. Without windings and silicon steel sheets, heat and resonance are avoided. In the process of controlling static and dynamic contacts of the alternating current contactor, overheating and over-high noise are avoided. 本发明公开种交流接触器的控制结构及控制方法，将原有技术的交流接触器电磁联结改为机械传动联结，用步进电机、匹配螺纹空心轴和实心轴、活动杆组合代替硅钢片、铜绕组，避免了原有交流接触器控制方法存在的线圈长期带电过高温升、过大噪音的问题，在稳定性、安全性、能耗方面具有很大程度改善，该结构不存在电磁联结关系，没有绕组和硅钢片不
