Recently, Menciusmotor came exciting news, the company's independent research and development of 1MW large motor has been successfully completed, this milestone marks the company in the field of motor research and development and manufacturing has taken a solid and key step.

The principle of a magnetic levitation motor is to use magnetic field force to suspend the rotor of the motor, achieving non-contact rotational motion, avoiding mechanical contact and friction, thereby improving the efficiency of the motor, reducing energy loss and noise pollution. Using magnetic levitation bearing technology to achieve high speed and maintenance free operation of the motor, solving users' high-speed demand, maintenance, and energy-saving issues at the system level; The standard series motors can be applied in various industries such as air compressors, blowers, ORC power generation, expanders, high-speed electric spindles, etc.

Nanometer measurement accuracy, bandwidth over 20kHz, temperaturestability ≤ 0.015%FS/K, applicable to ferromagnetic andnon-ferromagnetic materials. Probe integrated fully sealed design, sensitivityup to 6V/mm, -40°C -150°C widetemperature range, high signal-to-noise ratio, strong anti-interferenceability. 

Magnetic bearing adopting high-efficiency and high-precision 5-degree-of-freedomactive magnetic bearings, the maximum load capacity can reach more than 5 tons,and can realize ultra-high rotational speed of more than 100,000r/min, with nocontact, no friction, no need for lubrication, and with a long service life andlow loss.

Innovative control algorithm realizes double-loop frequencydecoupling control of current and displacement, integrating UFCC and SVCalgorithms, high-speed rotor vibration can be actively controlled, and thelevitation control accuracy can reach the micron level, which is better thanthe international standard of ISO14839/API617.

Maximum power reaches megawatt class, motor efficiency up to 98% ormore. Wide speed range, speed up to 100000r/min or more, directly drive theimpeller high-speed rotation, zero transmission loss.

high speed(up to 50000rpm),high power(1-1000kw),no wear and lownoise ,high precision control,real time suspension status monitoring,longworking life，

The successful production of 1MW large motor embodies the effortsand wisdom of the company's R & D team for many years. From the carefuldrawing of the design blueprint to the strict control of the production link,every step demonstrates the company's persistent pursuit of high-quality andhigh-performance products. During the research and development process, thetechnicians overcame many difficulties and solved a series of complex technicalproblems, including high power density design, heat dissipation optimization,material selection and so on, to ensure that the motor can meet the needs of avariety of complex working conditions while running efficiently and stably.

The successful production of the 1MW large motor not onlydemonstrates Mencius motor's strong independent innovation ability and profoundtechnology accumulation, but also further enhances the company's corecompetitiveness in the industry. It will be widely used in industrial fields,transportation fields, energy fields, such as: wind power generation, steelproduction, high-speed trains, electric vehicles, aircraft, ships,pharmaceutical factories, etc., to provide more powerful power support for the developmentof related industries. At the same time, this achievement has also made apositive contribution to the localization process of China's high-end motorequipment, and is expected to break the long-term monopoly situation of similarforeign products in the high-end market.

Company R & D person in charge said that the 1MW motor smoothlyoff the line is a new starting point, the future company will continue toincrease investment in research and development, continue to improve productquality and performance, with better products and services to return to themarket and customers, towards the goal of becoming the world's leading motormanufacturer.
