Permanent magnet synchronous submersible motor

This series of products mainly consists of high-efficiency submersible pumps and permanent magnet submersible three-phase synchronous motors, which work underwater. Compared with conventional QJ submersible electric pumps, its biggest advantage is high efficiency and energy saving. The motor adopts a permanent magnet submersible three-phase synchronous motor. During the operation of the motor, there is no excitation power loss or rotor copper loss. The efficiency is 3-5% higher than the specified value in GB/T2818 standard, and the power factor is 5-10% higher. At the same time, the motor has high starting performance and overload capacity, and can be controlled by general control equipment. The flow components of the water pump, such as impellers and guide shells, have been specially designed or manufactured using special processes, resulting in an efficiency 2-5% higher than the values specified in the GB/T2816 standard. It is a new generation of energy-saving and efficient pumping equipment. Please click on the link below to download/upload/file/20200613/20200613171442_24658.docx for specific model parameters

The permanent magnet high-efficiency submersible electric pump is a pumping and drainage equipment that is composed of a motor and a water pump that are rigidly connected and work underwater. Mainly used in continuously operating workplaces, with more significant energy-saving effects, such as water sources for water companies, factories, and mining enterprises.

The motor is a three-phase synchronous motor designed using permanent magnet theory. The interior of the motor is a water filled structure, and the winding is specially made of polymer waterproof material. The external cable and the motor winding are treated with waterproof insulation to ensure electrical waterproof and insulation reliability. The permanent magnet material of the motor is rare earth permanent magnet, and the permanent magnet steel is embedded in the rotor to form a permanent strong magnetic field, which interacts with the rotating magnetic field of the stator to form the working principle. The water pump adopts advanced and efficient hydraulic models to make the flow components, and the surface friction resistance of all water flows through is very small, resulting in high pump efficiency.
