Zhejiang Chuangmei Electromotor Co., Ltd. is located in Wenling City, a coastal city in central Zhejiang Province. It is recognized as a provincial-level science and technology-based small and medium-sized enterprise, as well as a municipal high-tech enterprise. The company primarily produces various types of permanent magnet synchronous motors (PMSMs). Its product portfolio includes two main categories: variable frequency drive permanent magnet synchronous motors and asynchronous-start permanent magnet synchronous motors. The company has obtained the China Energy-Saving Product Certification for its PMSMs. The power range spans from several tens of watts to 200 kW. Variable frequency drive motors can be custom-designed and manufactured with various operating speeds. The asynchronous-start PMSMs are available in 2-pole, 4-pole, 6-pole, and 8-pole configurations.
Our high-speed deep well pump, equipped with a DC brushless permanent magnet synchronous motor, is an advanced synchronous motor product developed independently by our company. This technology has been awarded a national invention patent by the China National Intellectual Property Administration and received the 2014 International Pump and Valve Industry Technology Innovation Award from Jung Industrial Media. We have also obtained multiple utility model patents related to the application of permanent magnet synchronous motors in pump systems.
Our certifications cover practical applications of permanent magnet synchronous motors across a wide range of centrifugal pumps, including deep well pumps, pipeline pumps, inline pumps, axial flow pumps, solar pumps, submersible pumps, and multi-stage centrifugal pumps. These also include structural innovations such as integrated and built-in motor controller designs. These are all conventional pump types that, after being upgraded with energy-efficient synchronous motor technology, exhibit significantly improved performance, supporting the advancement and modernization of the pump industry.
Our series of synchronous motor pumps is also directly applicable to solar-powered water supply systems. They support independent or simultaneous input from solar and grid power. Solar power can be connected directly without an inverter, and the system automatically adjusts its frequency and operation according to solar intensity. The solar energy utilization rate is higher than systems using MPPT technology, offering superior overall performance compared to other solar pump solutions.
In addition to our pump products, our permanent magnet synchronous motors—both asynchronous start and variable-frequency drive types—are widely applied in other general machinery, including textile machines, air compressors, and hydraulic presses. These motors effectively replace conventional asynchronous motors, achieving significant energy savings and higher efficiency.
We welcome collaboration and exchanges with manufacturers, distributors, end users, and functional departments committed to energy conservation and environmental protection. Let us work together to contribute to a cleaner, greener future with blue skies and white clouds.
All permanent magnet synchronous motor pumps (including plug-in, attached, and water pump types) and welding machines come with a one-year warranty. Within the warranty period, we will repair any quality issues under normal use free of charge. After the warranty expires, material and labor costs will be charged as needed. Transportation costs are the responsibility of the user.
First-level and special-grade high-frequency concrete vibrating rods are guaranteed to operate for 80 hours under normal use. If any quality issues arise during this period, replacement parts will be provided free of charge. If a quality issue occurs within the first 40 hours of use, the unit will be exchanged for a new one.
For warranty service, please call the company's toll-free hotline 400-82-8822166 at any time. For accessories service for users outside the province, we apologize that we do not provide door-to-door service. If necessary, please contact your local dealer.
