What is the structure and basic characteristics of a Permalloy core?
Permalloy cores typically refer to iron-nickel alloys. Permalloy cores are a widely used soft magnetic alloy. Through appropriate processes, magnetic properties can be effectively controlled, such as initial permeability greater than 105, high permeability exceeding 106, coercivity as low as 2‰ Oersted, and rectangularity close to 1 or 0. The face-centered cubic crystal structure of Permalloy exhibits good ductility, allowing it to be processed into 1μM ultra-thin strips and various application forms.

What is the manufacturing method for a Permalloy core?
Permalloy is an iron-nickel alloy with a nickel content between 35% and 90%. Permalloy is characterized by its high permeability in weak magnetic fields. Their saturation magnetic induction is typically between 0.6 and 1.0 T. Currently, permalloy cores on the market are all one-piece units. One-piece cores waste a significant amount of space during storage and transportation, making them inconvenient to handle. Therefore, there is a need to invent a new type of permalloy core to address this problem.

Sensor iron core manufacturer: Knowledge points of inductor iron core
Sensor iron core manufacturers believe that inductors are very important components in switch converters, such as energy storage and power filtering. There are many types of inductors, for example: used in different applications (from low frequency to high frequency), or the characteristics of inductors are affected by different iron core materials, etc. The inductors used in switch converters belong to high-frequency magnetic components, but due to various factors such as materials, working conditions (such as voltage, current), and ambient temperature, their characteristics and theoretical differences are relatively large.

Sensor core manufacturer: Core processing and characteristics
Sensor manufacturers believe that amorphous alloys have advantages such as high saturation magnetic induction intensity, low coercivity, and low loss, and are widely used in energy-saving and environmentally friendly power transformers. Currently, amorphous alloy cores adopt a near-rectangular stacked structure. The core has a large internal stress after molding, and its magnetic properties are severely damaged. It is necessary to eliminate these stresses through heat treatment and annealing.

Some common sense about iron cores, explained by a sensor iron core manufacturer
Sensor iron core manufacturers believe that traditional amorphous iron cores are affected by factors such as shearing equipment and strip winding methods. The lap joint structure of amorphous iron cores is basically 30 laminations per group, and the gap in the lap joint area is large, resulting in magnetic leakage, which leads to a large no-load current and excitation power of the amorphous iron core, affecting the performance of the transformer.

Sensor cores are divided into two categories: "iron loss" and "copper loss"
The input of any motor is never just input; there are always losses, and sensors are no exception. Generally, the losses in a sensor core are divided into two categories: "iron loss" and "copper loss". Because iron loss is independent of the load, it is also called "no-load loss". Copper loss is proportional to the load, so it is also called "load loss".

What is the main structure of the sensor iron core? How to perform related maintenance?
What is the main structure of the sensor core? The sensor core consists of a core body, magnets, and related electrical steel sheets. During the purchasing process, you should understand these components and their quality. Don't choose cheap products to reduce production efficiency.

How to select the sensor core? How to handle related failures?
The size of the sensor can be reduced under the AC state of the oral sensor. It is also generated in the iron core under the magnetization of AC. The power loss in the sensor iron core is usually called 'iron loss', which is caused by 'hysteresis loss' and 'eddy current loss'.
