Many people don't know much about injection-molded magnetic rotors, so this article will introduce what are injection-molded magnetic rotors and what types are there? What are the features and advantages? What are the main areas of application.
What is an injection-molded magnet rotor?
Plastic magnetic rotor is a composite material made of permanent magnet powder and nylon polymer (PA6, PA12, PPS) at high temperature, plastic magnetic products of any shape are made by injection molding machine through injection molding process, also known as plastic magnetic rotor. Commonly used in the market are injection-molded NdFeB magnet rotors and injection-molded ferrite magnet rotors, and production requires molds and magnetization fixtures.
What are the features (advantages) of injection-molded magnetic rotors?
1. High dimensional accuracy
2. Good surface finish
3. Good impact resistance
4. Easy to assemble and save labor costs
5. Compared with sintered magnetite, it is not easy to break and chip
6. Due to the injection molding process, the design freedom of the product shape is very high
7. The price is relatively low
8. Working temperature 20-150℃
Injection magnet rotor application;
Injection-molded nylon magnet rotor products are mainly used in: inverter air conditioners, floor-standing fans, range hoods, exhaust fans, vehicle speed sensors, vehicle cooling fans, bladeless fans, ceiling fans, electroacoustic devices, household appliances, instrumentation, medical , DC brushless motors, encoders, Hall sensors and other areas of daily life.
