Delivery of High Precision Motor Stator Winding Machine to the Customer's Factory
During the commissioning of this motor stator winding machine, we encountered many different problems. These problems need to be solved by our technicians one by one. Only when each problem is solved, then our equipment be shipped to customers.
When debugging this motor winding machine this time, our technicians encountered a problem, no matter how the debugging was done, the problem was not solved. There is only one day left before the delivery date. Several of the debugging colleagues are very guilty because have not solved the problem. If it cannot be resolved tonight, then the shipment will be postponed.
Despite encountering unprecedented problems, our debugging colleagues didn’t give up. Our technicians worked overtime at night until the early hours of the morning and repeatedly debugged, finally solved the problem, and successfully shipped the goods within the delivery time. In addition, the machining department and the business department are also working overtime to follow up on this issue in time.
This stator winding machine can realize precise wire arrangement without any wire damage, and the head and tail can be reserved. The end of the thread enters the slot of the insulating frame and the end of the thread is straightened, and the thread is automatically trimmed. The wire can be operated independently to meet different wire requirements and adapt to product diversification. Double station design, can realize the independent movement of left and right stations, and can also realize linkage, which is convenient for maintenance and replacement of parts.
At the same time, according to the company's reward regulations, the colleagues in the R&D and production department who participated in the overnight debugging of the equipment were commended, awarded the called "Little Expert in Tackling Key Problems", and awarded 1,000 yuan in cash. Although only four colleagues were able to receive the award this time, all the employees of HONEST have contributed a lot. Only when every colleague works together can this difficulty be solved. In the future, HONEST will definitely encounter more challenges and difficulties, stick to his beliefs, and don't give up easily. No matter how big the problem is, it can be solved successfully.
From November 22 to 24, 2023, a motor industry event will be held at the Shanghai New International Expo Center, which is the much-anticipated "2023 China International 27th Small Motor Technology, Magnetic Materials Technical Seminar and Exhibition".
As one of the core parts of new energy vehicles, the electric drive system has an important impact on the performance of new energy vehicles, and has important significance for the power, economy, comfort, safety, reliability, and durability of new energy vehicles. In addition, in terms of industry needs, low cost, miniaturization, and intelligence are the main trends. The electric drive system of an electric vehicle is mainly composed of four parts: drive motor, transmission, power converter and controller. The drive motor is the core of the electric drive system, and its performance and efficiency directly affect the performance of electric vehicles. The size and weight of the drive motor and transmission will also affect the overall efficiency of the vehicle. Power converters and controllers can help electric vehicles operate safely and reliably.
In the long term, the trend of flat wire motors is highly certain. In the first half of 2021, the penetration rate of flat wire motors among the top 15 vehicle models in terms of sales reached 28%, compared to just 14% in 2020. It is anticipated that by 2025, the proportion of flat wire motors in the drive systems of new energy vehicles will exceed 80%.
X-Pin motor technology allows for a reduction in the height of the linear segment at the end of the motor while maintaining a high slot fill factor. This results in a shorter overall motor length, saving copper wire usage and improving motor efficiency, thus achieving miniaturization.
In recent years, the market penetration of new energy passenger vehicles has continued to rise. Due to the high demand, existing cylindrical-wire motors have become insufficient in meeting the performance requirements of electric vehicle propulsion. Therefore, the substitution of flat-wire motors for cylindrical-wire motors is a highly certain trend for the future. Motor manufacturers are actively seeking high-capacity, high-quality production processes to meet market demands, with ongoing optimization and innovation in the manufacturing processes of flat-wire motor stators.
As is well known, the energy conversion efficiency of electric motors is around 90%, meaning that losses account for approximately 10%. Within the energy losses of a motor, copper loss, which is the heat generated by the current passing through the stator winding, constitutes about two-thirds of these losses.By adopting flat wire motors, the round wire windings are replaced with flat wire windings, increasing the amount of copper per unit area on the stator. This increases the copper fill factor to 20% to 30%, meaning more copper is packed into the stator slots. This effectively reduces winding resistance, and the lower the resistance of the winding, the higher the electrical efficiency. Consequently, it reduces copper losses.
