Introduction to a space-saving, easily transportable permalloy core
2021-12-29
Generally speaking, Permalloy core it refers to an iron-nickel alloy with a nickel content between 30% and 89%. Permalloy is characterized by its high permeability in weak magnetic fields. It is a widely used soft magnetic alloy. Magnetic properties can be effectively controlled through appropriate processes. Face-centered cubic crystal structure permalloy has good plasticity and can be processed into ultra-thin strips and various forms. Suitable for high-frequency low-voltage transformers, leakage protection switch cores, common-mode choke cores, and current transformer cores. Currently, permalloy cores on the market are all arranged as a whole, but the overall arrangement of cores wastes a lot of space during storage or transportation, making storage and transportation inconvenient. Therefore, it is necessary to invent a permalloy punched core to solve the above problems.
To solve the problems raised in the above background technology, technicians provide a space-saving and easy-to-transport permalloy core. To achieve the above purpose, it adopts the following technical scheme: A permalloy core, including a core, a core 2, and a fixing plate, wherein the middle of one end of the core is fixedly connected with a plug, and the middle of one end of the core 2 is provided with a slot, and the slot cooperates with the plug; two fixing plates are provided; both fixing plates are tightened with screws; four screws are set, and the four screws are equidistantly distributed, and the number of threaded holes is equal to the number of screws.
It should be noted that when making this permalloy core: the core and core 2 are made of multiple stacked laminations, and each lamination is provided with a positioning hole. The top of the cushion is attached to the bottom of the movable frame, and the cushion is made of rubber material. A rotating shaft is movably connected in the shaft hole, and one end of the rotating shaft passes through the permalloy core. A wear-resistant layer is fixedly connected to the inner wall of the movable frame, and the inner wall of the wear-resistant layer is attached to the permalloy core. The number of screws is set to four, and the four screws are arranged in a rectangular shape. The outer diameter of the upper washer is larger than the outer diameter of the upper nut, and the permalloy core is fixedly connected to the external motor device. The core and core 2 are fixedly connected to the fixing plate by screws. Two fixing plates are symmetrically arranged around the core.
This new Permalloy core The technical effects and advantages are as follows: Due to the optimized design and structure, through reasonable setting, the core and core 2 are firmly fixed with the fixing plate, and the core and core 2 can be separated when not in use, storage, or transportation, avoiding waste of space during storage or transportation, saving more space, making it easier to move and transport, and having good market development potential.
