Problems solved by technology
[0002] The drive of the electromagnet of the traditional industrial sewing machine is always driven by a constant voltage power supply. Since the electromagnet needs to overcome a relatively large static friction force at the beginning of the action, and then the electromagnet moves to the specified position, keep the position of the electromagnet. , only a small force is needed, and there is no need to maintain such a large force at the beginning of the initial action. Therefore, using a constant voltage power supply to drive the electromagnet is a great waste of energy in the process of maintaining the position of the electromagnet. And it will also cause the electromagnet to heat for a long time, which greatly affects the service life of the electromagnet. Therefore, the disadvantages of using a constant voltage power supply to drive the electromagnet are obvious, and the use of voltage regulation to drive the electromagnet according to actual needs Technology can solve this problem very well
