This customer is an manufacturer of electric motor rotor iron cores, their plant covers an area of 10,000 square meters. They specifically purchased Goanwin's H frame six-column high-speed precision press and high-quality molds made in Japan to improve their product quality.
Currently, multiple Goanwin high speed presses have been installed to closely cooperate with them to meet their production needs for spare parts and improve the performance and quality of their products.
The stable performance of Goanwin presses has also strengthened their confidence in long-term cooperation. At the same time, this collaboration also signifies the recognition of Goanwin's strength and technology.
The fixed part in the motor is called the stator, on which pairs of stationary main magnetic poles with DC excitation are installed. The rotating part (rotor) is called the armature iron core, on which the armature windings need to be installed. When energized, it generates induced electromotive force and acts as a rotating magnetic field to generate electromagnetic torque for energy conversion.
The motor core is made of silicon steel sheets. This material has good magnetic permeability but poor electrical conductivity. The motor generates magnetic force through coil winding and operates based on this magnetic force. However, due to the alternating magnetic field generating current in the iron core, if the iron core has strong electrical conductivity, it is equivalent to a closed short-circuit circuit and will generate heat, known as eddy currents. This is the same principle as the electromagnetic induction cooktop heating the bottom of a pot through an electromagnetic field. Therefore, in order to suppress these eddy currents, silicon steel materials with poor electrical conductivity are used, and the silicon steel sheets are used piece by piece instead of a solid core.
The delivery of the machine is no longer the end but the starting point of the service. In the future, with the continuous introduction of new technologies and comprehensive solutions, Goanwin is expected to become the provider of the best cost-effective solution.
