Abstract

The utility model relates to a magnetoelectric electromagnet, which is characterized in that a permanent magnet is added on an iron core of a common electromagnet. The permanent magnet is arranged on a moving iron core or a fixed iron core. For the magnetoelectric electromagnet of the utility model adds the permanent magnet on the iron core, the self-holding in the replacing or closing state is achieved, that is to say, the 0 or 1 state is kept at any time. When the former state is needed to change, an anode or cathode strong electric impulse can be added at the two ends of the electromagnetic loops. As long as the electricity is no longer connected, the electrified state is kept all the time without the consumption of the electricity. The utility model has the advantages of energy saving, running without noise, no heating and increasing the durability of the electromagnetic loops. The application is wide, and the utility model can be applied on the high power switch of continuous running, and the energy saving effect is obvious.

Description

A kind of magneto-electric electromagnet

The utility model relates to electric elements, specifically a kind of magneto-electric electromagnet.

The application of electromagnet is very extensive, and it is mainly used in machinery and the electric equipment products.As electromagnetic clutch, AC/DC contactor, electromagnetically operated valves etc. are converted to electric energy on the various devices of mechanical energy all will use electromagnet.And existing electromagnet has the following disadvantages it owing to have certain defective on the structure when using: power consumption during at closure state, heating; Also existing hot-tempered of alternating current, and manufacturing cost height.

The purpose of this utility model provides and a kind ofly can overcome existing electromagnetism iron deficioncy, energy-conservation, no hot-tempered sound operation, does not generate heat the magneto-electric electromagnet in the useful life of energy extension coil.

The utility model is achieved in that on the iron core of common electromagnetism has increased permanent magnet, this permanent magnet be loaded on moving iron core or the fixed core or.Realized that electromagnet resets or the self-sustaining of closure state.

When feature of the present utility model also was to use, the forceful electric power pulse that adds a plus or minus at the electromagnet coil two ends was to change original state.

Magneto-electric electromagnet of the present utility model has been owing to increased permanent magnet on iron core, realized resetting or the self-sustaining during closure state, just whenever keeps 0 or 1 state.When needs change previous status, add the forceful electric power pulse of a plus or minus at the electromagnet coil two ends, if no longer energising, the state after always keeping leading to, and no longer power consumption.This magneto-electric electromagnet has energy-conservation, no hot-tempered sound operation, does not generate heat, and can prolong advantages such as electromagnet coil useful life.Its application is also very extensive, is used on the high power switch of continuous operation, and energy-saving effect is very remarkable.As be applied to (CJ 10-40) on the A.C. contactor, keep the power consumption of operating state time institute be 0.025 degree/hour, active energy can be saved about 5000 hours and be worth a 40A A.C. contactor by 0.4 yuan/degree.

Fig. 1 is a structural representation of the present utility model;

Fig. 2,3,4,5,6,7,8,9 is respectively several embodiment of the present utility model.

Switching circuit figure when Figure 10,11 is a change state of the present utility model.

Among the figure, the 1-fixed core, 2-moves iron core, 3-permanent magnet, 4-coil.

As shown in the figure, the utility model has increased permanent magnet 3 on the iron core of the general electromagnet of being made up of fixed core 1, moving iron core 2, coil 4, and this permanent magnet is loaded on moving iron core or the fixed core.Fig. 2 to Fig. 9 is several different embodiment (wherein coil does not draw, and coil all is contained on the fixed core), and permanent magnet is loaded on appropriate location on fixed core or the moving iron core, can reach the purpose of this utility model.

When needs change previous status, add the forceful electric power pulse of a plus or minus at the electromagnet coil two ends, shown in Figure 10,11.Figure 10 is for finishing starting and stopping with a knob, Figure 11 is for finishing starting and stopping with two knobs.

Claims
