China Dc Motor Manufacturer – SR motor 110kw 30000 rpm for high-speed and high-power equipment – INDEX Detail:




Motors are a huge industry. With the development of new economy and high-tech economy, the demand for high-performance motors is rapidly increasing. Among them, the high-speed motor of more than 10kw, more than 10000rpm to 200000rpm, is a peak of current motor technology, a development direction, and is used in equipment and special equipment, such as turbocharger and other military and civilian fields. The technical and economic value is great. The United States, Germany, Japan and other development. my country’s high-speed and high-power motor technology is very weak. This is also one of the reasons why my country’s equipment performance lags behind these countries.


High-speed motors, especially high-speed and high-power motors, are a complex technical system that spans multiple disciplines and is challenging. There are the following technical difficulties:

1. Bearing technology. Our company uses magnetic bearing technology.

2. Rotor structure and strength. The rotor of the high-speed motor uses carbon fiber hoop technology.

3. Rotor dynamics simulation.

4. Control system. High-speed control systems are more complex, especially the selection of high-speed algorithms and electronic components.

5. Vibration and noise control technology.

6. Heat treatment and cooling technology.

7. Process and assembly technology.


 Switched reluctance motor (SRD) is a high-speed motor drive system with very superior performance. It does not use rare earth materials, and its high-speed characteristics are all current motors. However, its technology is complex and globally recognized as difficult. Highly developed abroad. Chinese enterprises have been developing for 25 years, but in fact have not mastered their core technologies.

   After more than 10 years of continuous development and research and development, our company and team have developed into a well-known switched reluctance motor enterprise in the industry, and established a complete high-speed SRD technology system. Established current array direct torque control algorithm, power saving algorithm under variable load and variable speed conditions, large inductance switched reluctance motor mute control strategy, multi-parameter adaptive adjustment control algorithm, high-precision dynamic mathematical modeling technology and other global advanced controls. Systems and Electromagnetic Computing Technology. At the same time, the company has established a technical system for high-speed SRD within 50,000 rpm.

Single speed ratio within 8000 rpm Within 100kw machinery, vehicles, etc. cooperate
Single speed ratio within 15000 rpm Within 150kw cooperate




At the same time, our company participated in the National Natural Science Foundation of China International Cooperation Project NSFC-DFG (Sino-German): 25,000 RPM high-speed amorphous alloy switched reluctance motor technology and industrialization research for electric vehicles (78-5171101324). We are a participating unit, entrusted by the main unit Harbin Institute of Technology, responsible for the development of the high-speed controller system.

A high-speed switched reluctance motor project using iron-based amorphous alloy materials, and is cooperating with Tsinghua University.

The high speed of small power motors (within 3kw) and the high speed of medium and high power motors (5kw-200kw) are carried out simultaneously. The speed is set at 40,000 rpm level. The main application areas are:

 High-speed household appliances (low power)

 Molecular pumps (centrifugal pumps) and other pump centrifugal equipment (small and medium power) that require high-speed operation

 Instrumentation and test equipment in medical and other fields (small and medium power)

 Large-scale industrial equipment that requires high-speed operation (50kw-200kw medium and high power)

 New energy vehicle field (30kw-150kw medium and high power)

The fields that require high-speed motors are mainly for quick-refrigeration centrifuges, industrial high-speed centrifugal separators, laboratory dispersers, vacuum pressure gauges, waste heat power generation (high-speed switched reluctance start, power generation integrated machine), molecular pumps, large high-speed blowers, large High-speed refrigeration compressors, etc.
