What Is a Custom Stator?
A custom stator is a precision-engineered stator core designed and manufactured to meet specific motor performance requirements—rather than using standard, off-the-shelf designs. Custom stators allow motor designers to optimize:
- Slot/Pole geometry – Tailored to achieve specific torque, RPM, or efficiency targets
- Lamination thickness – Optimized for the motor's operating frequency
- Stack height – Adjusted to match power and torque requirements
- Material grade – Selected for optimal magnetic performance
- Exclusive design rights – Proprietary designs that competitors cannot copy
ⓘ Custom stator insight: "A custom stator allows you to break free from standard design constraints—delivering the exact magnetic performance your drone, robot, or industrial motor requires."
Reenives manufactures custom stator cores for drone motors using imported 0.2mm silicon steel, progressive stamping dies (or laser cutting for prototypes), and automated epoxy powder coating—delivering optimized magnetic performance for demanding UAV, robotics, and industrial BLDC applications.

FAQ: Custom Stator Core Technical Questions
A custom stator is a precision-engineered stator core designed to your exact specifications—rather than using standard off-the-shelf designs. You need a custom stator when: (1) standard designs don't meet your performance targets, (2) you have unique size or geometry constraints, (3) you want to optimize efficiency or torque density for your specific application, (4) you need exclusive design rights for competitive advantage, or (5) you're developing a new motor from the ground up. Custom stators allow you to achieve performance that standard designs cannot match.
Reenives supports any slot/pole configuration for custom stator cores including: 9N12P (most common for FPV and racing drones), 12N14P (higher torque density for 5-inch+ drones), 24N22P (heavy-lift and logistics), 36N30P (eVTOL and extreme power), 12N8P (robot servo motors), 24N16P (industrial actuators), and any custom combination you require. Private mould development is available for high-volume OEM projects with exclusive design rights.
Reenives offers custom stator laminations in multiple thicknesses: 0.15mm (ultimate high-frequency performance), 0.20mm (optimal balance for most drone and BLDC applications), 0.27mm (mid-frequency cost-performance balance), 0.35mm (standard industrial motors), and 0.50mm (low-frequency cost-sensitive applications). Thinner laminations reduce core loss at higher frequencies, enabling longer flight times and cooler operation. We can customize thickness to your specific requirements.
Reenives supports all major CRNGO electrical steel grades for custom stator cores including: 35PN210 (premium grade, 0.20mm, for high-performance drone motors), 35PN250 (high-grade, 0.20mm), 50A470 (standard industrial, 0.35mm), 50A600 (cost-effective, 0.35mm), and custom grades upon request. All materials are sourced from Nippon Steel and Baowu with full material certificates. We can recommend the optimal grade for your specific motor application.
Reenives offers flexible minimum order quantities for custom stator cores depending on the manufacturing method: (1) Laser cutting prototypes: as few as 10–50 units for design validation, (2) Progressive stamping (low-volume): 500–1,000 units, (3) Progressive stamping (high-volume): 5,000+ units for optimal cost efficiency. We work with customers at every stage—from prototyping to high-volume production—with private mould development for exclusive designs.
The custom stator development timeline depends on complexity: (1) Laser cutting prototypes: 2–4 weeks for design validation, (2) Progressive stamping tooling development: 4–8 weeks for tooling design and manufacturing, (3) Production ramp-up: 2–4 weeks for validation and volume production. Total timeline typically ranges from 4–12 weeks depending on project complexity and volume requirements. Reenives works closely with customers to accelerate development where possible.
Yes. Reenives offers private mould development with exclusive design rights for high-volume OEM projects. This means the custom stator design, tooling, and geometry are proprietary to your company—competitors cannot copy your design. We sign non-disclosure agreements (NDAs) and maintain strict confidentiality on all custom projects. Exclusive designs are available for both progressive stamping and laser cutting manufacturing methods.
