How Are Arc Segment Neodymium Magnets Applied in BLDC Motors

Arc segment neodymium magnets, also known as motor arc tiles, are the core magnetic component inside brushless DC (BLDC) motor. They are installed closely on the inner wall of the motor rotor, forming a circular magnetic field perfectly matched with the stator structure.

Most arc magnet adopts radial magnetization, which generates stable and uniform magnetic flux. This helps the motor run smoothly, reduces torque fluctuation and noise during operation. High-temperature grades such as N35SH, N42SH are commonly selected to avoid demagnetization from long-time operating heat.

They are widely equipped in automotive BLDC motor, fan motor, pump motor, electric bicycle drive motor and servo motor. Precise size tolerance and qualified surface coating guarantee long service life under continuous working conditions.
