Characteristics of cold stamping process of electric motor core
Iron core is one of the effective parts of the motor, and the manufacturing process of iron core has a great influence on the operation performance of the motor. The iron core manufacturing process includes two parts: punching sheet manufacturing and iron core pressing. Today, the small editor explains the characteristics of the cold stamping process for you.

1, high material utilization rate. The workpiece can be sheathed, and the stamping part can be used only after a small amount of cutting, or even without cutting.
2, mold manufacturing cycle principal, its manufacturing cost is higher.
3, reliable accuracy. The size accuracy of the workpiece is mainly determined by the mold, and the relationship with the operator is very small. Therefore, the size of the workpiece is stable and interchangeable.
4, the operation is simple. It mainly depends on the punching press and mold to carry on the work. The operator only does the simple feed work, and the technical level of the operator is low.
5, rush shear speed, pressure is large, prone to personal accidents.
6, work noise. Cold stamping is an impact job, and each time it is stamped, it makes a noise. Shear shop is one of the most affected areas of noise pollution.
7, high productivity. The punch machine works fast, the stamping process is easy to realize mechanization and automation, and the productivity is very high.
Due to the long mold manufacturing cycle and high manufacturing costs, it is not economical to adopt cold stamping technology when the number of workpieces is not large. Only in mass production, the cost of die manufacturing has little impact on the cost of the workpiece, so the cold stamping process becomes an economical and reliable processing method.
Brushless motor core is the rotor and stator of the brushless motor. Let us understand the specific knowledge of the brushless motor core in detail. Thank you for your reading, hope to deepen your understanding of the brushless motor core.
Analysis of Brushless Motor Structure: In structure, Brushless Motor and Brushless Motor have similarities, as well as rotors and stators, but contrary to the structure of Brushless Motor; The rotor of the brush motor is a coil winding, the Hedongli output shaft is connected, and the stator is a permanent magnet steel; The rotor of the brushless motor is a permanent magnetic magnet steel, which is connected with the output shaft together with the shell. The stator is a winding coil. The brushless motor is used to alternately transform the electromagnetic field. Therefore, it is called a brushless motor.
The company has a professional mold manufacturing plant, with the production of large and medium-sized motor stamping dies, injection molds, all kinds of drawing deep molds, now produce the maximum diameter of the falling die 1200 mm. The company has senior professional personnel, high degree of automation in the production process, reliable quality. We welcome our company to negotiate and cooperate in the process of equipment investment and production capacity improvement.
Brushless motor: It is usually used in equipment with relatively high control requirements and high speed, such as AVIONICS, precision instruments, etc., which strictly controls the speed of the motor and has a high speed, and is now the most advanced dry hand. The DIAHOUR dry hand machine, a brushless motor made by Dior Electric, also uses this type of motor. The cost of the motor and controller is very high, so the more high-end equipment is used later.
