Product Overview
The industrial segment neodymium magnet is a rare‑earth magnetic component shaped as an arc or sector piece for use in rotating and static applications. Its profile is specifically suited to cylindrical assemblies such as motor rotors and stators, where magnetic field distribution and compact form factor are essential.
Compared with simple block magnets, segmented arcs reduce gaps in multi‑piece assemblies and improve magnetic flux continuity. This makes them valuable in applications where torque performance, repeatability, and mechanical fit all matter.
Material & Magnetization
- Material: Sintered Nd–Fe–B (neodymium iron boron)
- Grades Available: N35, N42, N48, N52 - chosen based on torque, temperature and cost constraints
- Magnetization Direction: Radial (standard) or axial; custom patterns available
- Coating Options: Nickel‑copper‑nickel (standard), epoxy or zinc where enhanced surface protection is needed
- Temperature: Designed for typical industrial environments; high temperature grades on request
NdFeB materials provide high magnetic energy density compared with ferrite or Alnico magnets, enabling stronger magnetic circuits with reduced magnet volume.
Typical Applications
Segment magnets are found in a range of industrial and electro‑mechanical systems, including:
- Electric Motors (Brushless/BLDC, Stepper): Arcs installed in rotor assemblies to generate uniform flux around the air gap.
- Actuators: Where controlled magnetic force across a specific arc angle is required.
- Generators and Alternators: For compact, efficient flux paths in rotating electrical machines.
- Automation Equipment: Linear or rotary motion systems requiring repeatable magnetic positioning.
Because they are manufactured to tight dimensional tolerances, these segments help minimize assembly variations and improve performance consistency across production batches.
Design & Integration Tips
- Air Gap Management: Ensure segment dimensions and housing tolerances are specified together; small gaps can result in significant torque drop.
- Matched Sets: For multi‑pole designs, matched flux segments reduce imbalance and vibration.
- Thermal Considerations: If operating near temperature limits, specify high‑temp grades to avoid demagnetization and retain field strength.
Providing detailed drawings (OD, ID, thickness, angle) early in the procurement process speeds quoting and machining setup.
