Zhejiang Chuangmei Electromechanical Co., Ltd.



Zhejiang Chuangmei Electromechanical Co., Ltd. is located in Wenling City, a coastal city in central Zhejiang. The company is a provincial science and technology SME, a municipal high-tech enterprise, and currently produces various types of permanent magnet synchronous motors. There are two types of variable frequency drive permanent magnet synchronous motor and asynchronous start permanent magnet synchronous motor, and the company has obtained the Chinese energy-saving product certification certificate of permanent magnet synchronous motor. The power is from tens of W to 200KW, and the various speeds of the variable frequency drive can be designed and produced. The rotating speed of asynchronous start synchronous motor has 2, 4, 6, and 8 poles.

The high-speed deep well pump of DC brushless permanent magnet synchronous motor is the first synchronous motor product developed by our company. At present, this technology has won the invention patent of the State Intellectual Property Office, and was awarded the 2014 international pump and valve industry technology innovation by Rongge Industrial Media. Subsequently, we obtained 13 utility model patents in the application of permanent magnet synchronous motors in the pump (there are several inventions and international patents in the declaration). When synchronous motors were not applied in the entire pump industry, we have already achieved so many patented technologies and are in the leading position in the pump industry.

Among the patents we have authorized, include utility model patents for the application of synchronous motors in various types of centrifugal pumps such as deep well pumps, pipeline pumps, tube pumps, axial pumps, solar pumps, submersible pumps, multistage centrifugal pumps, etc. And there are integrated and built-in controllers in structure. These pumps are conventional pumps, but after the synchronous motor energy-saving technology transformation, there will be excellent pump products that will promote the the comprehensive upgrading of the pump industry. Our synchronous motor pump series can also be directly applied to solar water supply. Solar energy and commercial power can be input separately or simultaneously. Solar energy can be directly connected to the power supply. It can automatically convert to automatic frequency conversion according to the strength of sunlight, and does not require inverter conversion. Solar energy utilization is higher than MPPT function, and the overall performance is more advanced than solar pumps which use other technologies.

In addition to the application of various types of synchronous motor products, asynchronous start permanent magnet synchronous motor and variable frequency drive permanent magnet synchronous motor are also applied to the power of other general machinery in various fields such as textile machines, air compressors and hydraulic presses, which can replace the old-fashioned asynchronous motor to achieve high efficiency and energy saving.

We are willing to cooperate with all kinds of production, sales, use and functional departments in the world that are interested in energy conservation and environmental protection, and work hard to restore blue sky and white clouds.
