Precision Optimization Design Technology: By employing the original approach that combines analysis and modern numerical computation, the performance simulations under the entire operating conditions of the motor system is conducted, and the multi-field coupling calculation of the motor body is carried out. This enables the accurate optimization of the operation performance of each series of products, resulting in a precise optimization design technology applicable to various product series and ensuring the optimal product parameter matching and operating performance.

The continued reliance on traditional approaches or a single modern numerical calculation method makes it difficult to achieve the comprehensive optimization of the motor body performance and the performance matching requirements with the system, let alone the consistency of product performance.

Energy-saving Technologies: By optimizing the magnetic circuit structure, parameters, and electromagnetic load of the motor, its losses are minimized, achieving very high efficiency that saves both energy and materials. All general products far exceed the highest energy efficiency standards both at home and abroad (i.e., level 1 energy efficiency / international IE5 energy efficiency). The average efficiency is 10% to 30% higher than that of asynchronous motors, and the power saving rate can reach 10% to 50%.

Most products are below the level 3 energy efficiency standard, with only a few meeting level 2 or approaching the level 1 standard.

Reliability Technology: The issue of demagnetization has been successfully addressed, ensuring reliable long-term operation in harsh environments. The motor can operate for up to ten years without experiencing any demagnetization.

The issue of demagnetization has not been effectively addressed. The actual operation lifespan is relatively short, and demagnetization occurs frequently.

Serialized and Standardized Design Technology: Specialized software for the design of serialized products have been developed, along with technical standards, manufacturing process standards, and product inspection standards. This enables the mass production of serialized high-efficiency and energy-saving permanent magnet motors. These products can directly replace asynchronous motors of the same specifications, and all the produced permanent magnet motors meet level-1 energy efficiency standards.

No attention has been paid to the research on commonality technologies, serialized design technologies and other aspects. The product varieties and specifications are single, and the serialized design capacity of products has not been formed.
