Product Overview
When your motor or generator demands maximum flux density in a curved geometry, our ISO 14001 certified sintered neodymium iron boron (NdFeB) arc magnets deliver. Produced in an environmentally-managed facility, every arc segment meets tight ±0.05 mm tolerances and is 100% inspected for magnetic uniformity—ideal for servo motors, BLDC motors, wind-turbine generators, and magnetic couplings.
