WATER PUMP ROTORS
High-performance Filter Impellers
The electronic water pump rotor employs high-efficiency magnetic materials in a compact design, resulting in a consistent power output. Its exact rotation performance and low energy consumption make it a popular choice for water pump systems in automobiles, home appliances, and industrial equipment. It offers great efficiency and stability during extended periods of operation.
Water Pump Rotor Composition
- Rotor: As the heart of a water pump, the rotor is a crucial part of the body and is usually connected to the motor by a shaft. It contains high-strength magnets and metals like stainless steel or aluminium. Being the primary part in rotation, it generates centrifugal force to drive water flow and ensure the continuity of flow and pressure in water pumps.
- Impeller: It’s the rotating member attached to the rotor, with most models mounted inside a water pump. The impeller consists of metal, plastic, or composite material; it rotates with the action of driving water, enabling the pump to function and shift liquids effectively.
- Seals: Seals can be installed in the gap between the pump housing and the rotor to prevent liquid leakage and maintain the pump’s internal seal. They are generally made of heat-resistant, corrosion-resistant rubber or fluoro rubber. Seals effectively prevent water leakage, reducing energy loss and improving efficiency.
- Bearings: Bearings are fitted on either side of the rotor to ensure smooth rotation. Bearings are usually ball or sliding bearings, reducing friction and supporting high loads during rotation.
- Motor: The motor is considered the power source of the water pump and is usually situated outside the pump body. It rotates the rotor, enabling the impeller to create power and move the water. The motor uses a high-efficiency electric motor that ensures low energy consumption and high torque output.
- Pump Housing: The housing of the water pump is its outer structure, typically made of cast iron or high-strength composite materials that can provide a robust shell and good sealability. It contains the rotor and impeller inside and allows the liquid to have a path of flow, ensuring a smooth flow of water through the pump.
Working Principle of Water Pump Rotor
The ECU of this electronic water pump system receives feedback signals from temperature and pressure sensors, allowing for real-time monitoring of numerous parameters such as water temperature and system pressure. The ECU will alter the PWM duty cycle and operating mode if the temperature or pressure exceeds the predefined thresholds. This signal is then transmitted back to the controller within the water pump, which adjusts the motor speed based on the received PWM signal. The motor speed change powers the impeller and rotor, which circulates the coolant in a closed-loop system, efficiently removing heat and keeping the cooling system at the right temperature, regardless of operating conditions.

Magnetic Field Distribution
The magnetic field distribution in the water pump rotor system is crucial for performance and efficiency. Sine wave magnetization technology would help keep the magnetic field inside the water pump rotor uniform and consistent. It will provide smooth and consistent magnetic force distribution with a lower level of vibrations and noise when operating the motor, enhancing stability and prolonging the system’s service life.
