Stator Magnets for DC Motor - Product Overview
Our stator magnets for DC motors are designed for manufacturers who need stable magnetic performance, reliable batch consistency, and flexible customization. Each magnet is produced with sintered NdFeB material and matched to the geometry and magnetic orientation required by your motor design.
Unlike generic catalogue magnets, these stator units are built for integration into OEM production lines-where tolerances, coating durability, and repeatability matter just as much as magnetic strength.
Specifications & Technical Options
- Material: Sintered Nd–Fe–B
- Available Grades: N35–N52
- Magnetization: Axial / Radial / Diametrical (configured per stator structure)
- Coating Choices: Ni-Cu-Ni (standard), Zinc, Epoxy, or customized protection
- Tolerance: ±0.05 mm (tighter tolerances available upon request)
- Operating Temp: Standard up to 80°C;
- Supply Form: Individual pieces or matched stator magnet sets
If you work from 2D/3D drawings, we can match pole layout, curvature, chamfers, adhesive bonding surfaces, and mounting requirements.
Why These Magnets Perform Well in Motor Applications
1. Strong magnetic flux for compact motor design
NdFeB allows the motor to reach required torque levels without enlarging the stator. This is valuable for compact drives, pump motors, and small actuators where space is limited.
2. Consistent batch performance
For motor plants running continuous production, magnetic deviation can cause noise, vibration, or output fluctuation. We control magnetization tolerance and coating thickness to keep batches stable.
3. Multiple coating options
Coating quality directly affects corrosion resistance, especially in humid or dusty environments. Nickel plating is standard, while epoxy coatings are often chosen for motors exposed to chemicals or moisture.
4. Adaptability to different motor structures
Whether for a flat core stator, compact DC motor, or multi-pole design, the magnets can be shaped and magnetized precisely to fit the slot geometry and magnetic path.

FAQ
Q1: Can these magnets match my stator or pole layout?
Yes. Send your drawing or motor spec sheet and we will match magnet size, magnetization, and coating accordingly.
Q2: What's the usual lead time for bulk orders?
Most custom stator sets ship in 3–5 weeks depending on complexity and order volume.
Q3: Can I test samples before purchasing larger quantities?
Absolutely. Many customers run 3–10 pcs tests for motor validation.
Q4: Do you offer high-temperature stator magnets?
Yes, including higher-grade NdFeB and coating combinations for motors running under elevated temperature.
