Heat Treatment for Stator and Rotor in China
This heat treatment will let the iron loss down by about 20% and Improve the core performance. Fit for the motor which is required high efficiency. We have advanced stator and rotor heat treatment equipment such as chain continuous.
Why Use Heat Treatment for Lamination Stacks
The stator and rotor are one of important components of the air-conditioning refrigerator compressor motor. After the stamping is completed, a heat treatment process is required.
Heat treatment in motor lamination manufacturing is a critical process that involves the controlled heating and cooling of stator and rotor stacks to improve their mechanical and magnetic properties. This process is essential for enhancing the performance, efficiency, and longevity of motors. By altering the microstructure of the steel, heat treatment reduces residual stresses, increases strength, and optimizes the magnetic characteristics of the laminations.
Improve the hardness and toughness
Improve the structure of the metal stator and rotor, increase the material hardness and toughness, make the stator more durable, and extend the life of the motor.
Optimize silicon steel sheet materials
Heat treatment can remove impurities, adjust alloy composition, improve material properties, and ensure stator quality.
Ensure the processing accuracy
Heat treatment can adjust the size and shape of the metal stator by controlling temperature, cooling rate, and other conditions to maintain its processing accuracy.
Stator and Rotor Heat Treatment
If the stator laminations or rotor laminations are welded or interlocked, they are less likely to loosen during annealing and maintain good dimensional tolerances.
However, if the stator and rotor are bonded laminations or loose laminations, we must design custom fixtures to ensure that the laminations do not come loose during the annealing process. The annealed laminates are then bonded or coated for subsequent processes. This will increase production costs due to the design and investment of additional batches of lamination fixtures for annealing.
Annealing Motor Laminations
Heat treatment processes can significantly improve the electrical performance of silicon steel laminates and motor/generator/transformer cores. Throughout the annealing process, dew point, air percentage, H2, CO, CO2 gas percentage and gas emissions are carefully monitored to ensure appropriate grain growth and metallurgical results are achieved for each application, including increased permeability and reduced iron loss if necessary.
