As a leading manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in the production of high-quality magnet rotors for automotive pump motors. Our OEM Automotive Pump Motor Magnet Rotor is engineered with advanced PA6/PPS and NdFeB materials, delivering exceptional precision of ±0.02mm and outstanding resistance to high vibration. Since our establishment in 2017, we have been committed to providing reliable components that meet the rigorous demands of the automotive industry.
This magnet rotor is designed to be a critical component in electric coolant pumps, oil pumps, and other automotive fluid systems. The combination of PA6 (Polyamide 6) and PPS (Polyphenylene Sulfide) as the base material ensures excellent thermal stability, chemical resistance, and dimensional accuracy. The embedded NdFeB (Neodymium Iron Boron) magnets provide high magnetic flux density, enabling efficient motor performance. With a precision tolerance of ±0.02mm, each rotor guarantees a perfect fit and balanced rotation, reducing energy loss and wear.
Our manufacturing process strictly follows the TS16969 quality management system, ensuring every rotor meets the highest standards of reliability and consistency. The rotors are subjected to rigorous testing for vibration resistance, magnetic strength, and dimensional accuracy. Let's explore the key features and benefits:

Frequently Asked Questions (FAQ)
-
What is the typical lead time for OEM orders?
Lead time depends on quantity and complexity. For standard rotors, it is usually 15-25 working days. Custom designs may require additional time for tooling. -
Can you provide samples for testing?
Yes, we can supply samples. Sample costs are negotiable, and we can discuss return of sample fees upon bulk orders. -
What is the minimum order quantity (MOQ)?
MOQ for standard items is 500 pieces. For custom designs, MOQ may be higher depending on tooling requirements. -
Do you offer PA6 and PPS options for the same rotor design?
Yes, we can mold the rotor with either PA6 or PPS material based on your application needs. Both materials are compatible with the NdFeB magnet insert. -
How do you ensure the ±0.02mm precision?
We use precision molds and CNC machining centers, along with 100% inspection using CMM (Coordinate Measuring Machine) and go/no-go gauges. -
Can the rotor withstand high temperatures?
Yes, depending on material selection. PPS offers a continuous operating temperature of up to 220°C, while PA6 is suitable for up to 130°C. Please specify your temperature requirements. -
Is the rotor balanced dynamically?
We offer dynamic balancing as an option. Standard rotors are statically balanced; for high-speed applications, dynamic balancing is recommended. -
What certifications do you hold?
Our factory is certified under TS16969 (automotive quality management system). We also comply with RoHS and REACH regulations upon request.
With a strong track record of supplying to diverse markets and a dedicated team of 51-100 employees, Changzhou Hongxinyutai Precision Mold Co., Ltd. is your reliable partner for high-quality magnet rotors.
