7. FAQ
Answer:
This customized heat resistant high coercivity strong rare earth stable nickel plated Arc Segment Permanent Magnet is a curved piece of magnet, typically made from neodymium (NdFeB), designed to fit around the inner diameter of motors. Its shape helps create a uniform magnetic field, making it ideal for use in brushless DC motors, servo motors, and generators.
Answer:
Depending on the grade, arc magnets can operate up to 80°C (standard) to 200°C (high-temp grades like UH/EH). It’s essential to match the grade with your motor’s thermal requirements.
