Problems solved by technology

[0009] 1. After the AC voltage is a fixed value (AC220V, AC110V or AC380V) and the excitation coil L is set, the "starting power" will also be determined accordingly, and cannot be adjusted according to different usage occasions, that is, the thrust is a fixed value and cannot be adjusted as needed set up;
[0010] 2. There is annoying AC noise;
[0011] 3. There is no "freewheeling circuit", and the moment the AC voltage is cut off, it is easy to generate electromagnetic interference

Abstract

The invention discloses a push-and-pull alternating electromagnet with adjustable starting power. The push-and-pull alternating electromagnet comprises a conventional push-and-pull alternating electromagnet composed of a movable iron core, a fixed iron core, a reset spring and an exciting coil, and an electronic unit. The electronic unit is composed of a first diode, a second diode, a third diode, a first one-way thyristor, a second one-way thyristor, a potentiometer and a control switch.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a "push-pull AC electromagnet with adjustable starting power" which operates in direct current with adjustable starting power. Background technique [0002] AC electromagnet (AC electromagnet) is a low-voltage electrical appliance that is widely used, and the push-pull AC electromagnet is one of the AC electromagnets. AC electromagnetic punch presses, AC electromagnetic nail guns, AC electromagnetic mashers, AC electromagnetic cutting machines and other equipment are equipped with push-pull AC electromagnets. [0003] figure 1 It is the working principle diagram of the push-pull AC electromagnet. This conventional push-pull AC electromagnet mainly consists of a moving iron core M, a static iron core G, a return spring F, and an excitation coil L. When the terminals A1 and A2 of the excitation coil L are connected to AC220V, AC110V or AC380V (hereinafter referre...
