FAQ
Q.What is an arc segment magnet?
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.
Q.What is the maximum operating temperature of an arc magnet?
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.
Q.Are your magnets RoHS and REACH compliant?
Yes. All our magnets meet RoHS and REACH standards. Compliance certificates can be provided upon request for international shipments and audits.
