Product Overview

We make segment neodymium magnets specifically for motor applications - when you need strong, uniform magnetic force and flexibility in shape. These segmented magnets are cut and assembled from NdFeB material to match the magnetic profile your motor requires.

If you're designing electric motors, actuators, or other rotating machinery, these magnets let you fine-tune performance with custom segment size, magnetization direction, and tolerance.

Technical Specifications

Material: NdFeB (sintered)
Shape: Segment (custom cut to motor profile)

Tolerance: ±0.5 mm or tighter if your design demands
Coating: Custom (Ni-Cu-Ni standard; others on request)
Magnetization Direction: Matched to your segment design (e.g. radial, arc-facing)
Operating Temperature: Standard grades ~80-100°C; higher performance grades available
Certifications: ISO9001 and other relevant industrial quality / export standards

Key Benefits for B2B Buyers

Optimized Magnetic Performance - segments allow you to shape the magnetic field to suit your motor design, improving efficiency and torque.
Design Flexibility - can adapt segment angles, thickness, and gap to match stators or rotor shape.
Bulk Manufacturing - we support large volume production with consistent quality control.
Durability - coatings and tight tolerances mean less risk of degradation over time or under load.
Cost-Effective - segmented magnets often cost less than monolithic parts for similar performance once in bulk.

Typical Applications

Brushless DC motors and PMSM types
Truck & automotive motor stators/rotors
Industrial fans, pumps and compressors
Electric tool motors where space and weight matter
Robotics joints and drives where torque and magnetic response are critical

Ordering & Custom Process

Share your motor's rotor/stator profile (dimensions, arc angles, inner & outer diameters).
Tell us desired magnetization direction and performance targets.
Select coating & grade based on temperature or environmental exposure.
We'll send a sample segment for your testing or validation.
Once approved, we produce with consistent QC and deliver in bulk.
