The utility model purpose is big, in light weight, the simple in structure high-performance electromagnet of a kind of work done of design.
Technical solution of the present utility model is: the high-performance electromagnet, by box hat (9), solenoid (7), magnetic pole (8), armature (2), iron yoke (6), drive rod (3) and power switch circuit are formed, solenoid (7) is located in the bobbin (6), magnetic pole (8) is located between the solenoid (7), armature (2) is provided with iron yoke (5) on every side, bobbin (6), armature (2), drive rod (3) is located in the box hat (9), power switch circuit is connected with solenoid (7), described armature (2) is provided with permanent magnet (1), permanent magnet (1) partly penetrates when original position in the iron yoke (5), armature (2) is as drive rod (3), perhaps permanent magnet (1) is located on the drive rod (3) as armature (2), permanent magnet (1) end face is mutually opposed with magnetic pole (8) end face, magnetic pole (8) end face is concordant with solenoid (7) end face, and permanent magnet (1) or magnetic pole (8) end face are provided with rubber washer (4).
Described power switch circuit is made up of power supply, reversing switch (11), capacitor (10) and solenoid (7), and capacitor (10) is connected with solenoid, reversing switch (11) one termination energizes, other end short circuit.
The utility model work done is big, in light weight, power consumption less, heating less, simple in structure, long-life, noiseless, no wave interference, but any direction is installed.The high-performance electromagnet armature is disposing permanent magnet, relies on side magnetic, and it is simple in structure, reduce resistance to make armature keep original position, strengthens initial actuating force.The mechanism that the high-performance electromagnet of long stroke adopts like pole to repel each other makes its initial actuating force bigger.The high-performance electromagnet adopts the partition direct current and just provides, the electrolytic capacitor of back pulse electric current is with the wiring of solenoid series connection, not power consumption when static and energy-conservation is not generated heat and can be dwindled the volume of electromagnet, and the stream that do not cut off the power supply during commutation circuit causes spark and telecommunication interference phenomenon.Circle end face alignment that the magnetic pole end face is collinear, the rubber washer in repulsion magnetic field is held in the setting of magnetic pole end face, both can obtain big as far as possible magnetic repulsion, can obtain an amount of self-sustaining power again.
