High-Precision NEV Micro Motor Stator Bracket – RationalDMIS CMM Verified with Absolute Concentricity
As a trusted manufacturer with over 6 years of expertise in precision molding, Changzhou Hongxinyutai Precision Mold Co., Ltd. is proud to offer this advanced NEV micro motor stator bracket that meets the stringent IATF16949 quality system. Our factory, spanning 1,000–3,000 square meters and staffed by 51–100 skilled professionals, leverages state-of-the-art injection molding technology and RationalDMIS CMM verification to deliver brackets with absolute concentricity – a critical requirement for new energy vehicle micro motors that demand consistent performance and minimal vibration. Every bracket is engineered to ensure reliable operation in electric power steering, brake systems, and cooling fan motors.
Key Features & Technical Specifications
- Material Excellence: Manufactured from high-performance engineering plastics such as PEEK, PPS, LCP, or customer-specified grades, offering exceptional thermal stability (up to 260°C), chemical resistance, and dimensional stability over a wide temperature range.
- Absolute Concentricity Control: The bracket’s bore-to-outer diameter concentricity is verified to ≤0.01 mm using a RationalDMIS coordinate measuring machine, ensuring minimal runout and reduced noise/vibration in the micro motor assembly.
- IATF16949 Quality Compliance: Our production process is fully aligned with IATF16949 (TS16969 equivalent), with 100% CMM inspection reports provided for each batch upon request. This guarantees traceability and defect-free delivery.
- RationalDMIS CMM Verification: Each critical dimension – including inner diameter, outer diameter, flatness, and parallelism – is measured via RationalDMIS software, generating detailed 3D reports that confirm absolute precision.
- Optimized for NEV Micro Motors: Designed to fit standard stator lamination stacks from 20 mm to 80 mm outer diameter, with customizable mounting holes and locating features to match various rotor and housing configurations.
- Injection Molding Precision: Our molds are machined to tolerances of ±0.005 mm, and the injection process is monitored in real-time to maintain consistent melt temperature, pressure, and cooling rate, resulting in warpage-free parts with excellent surface finish (Ra 0.4–0.8 μm).
| Parameter | Typical Value | Tolerance |
|---|---|---|
| Inner Diameter (ID) | 10 – 60 mm | ±0.02 mm |
| Outer Diameter (OD) | 20 – 100 mm | ±0.03 mm |
| Height | 5 – 30 mm | ±0.05 mm |
| Concentricity | ≤0.01 mm | CMM verified 100% |
| Surface Roughness | Ra 0.4 – 0.8 μm | As per mold finish |
| Operating Temperature | -40°C to +260°C | Dependent on material |
| Certification | IATF16949 | Full batch traceability |

Frequently Asked Questions (FAQ)
-
Q: What materials are available for the stator bracket?
A: We offer a range of engineering plastics including PEEK, PPS, LCP, PA9T, and other high-temperature thermoplastics. The material can be tailored to your specific thermal, mechanical, and dielectric requirements. -
Q: How is the concentricity verified?
A: Every bracket is measured on a RationalDMIS CMM using a dedicated fixture. The concentricity value is reported in the inspection certificate, typically within ≤0.01 mm. -
Q: Can you customize the bracket dimensions?
A: Yes, we can adjust inner/outer diameter, height, wall thickness, and add features like slots or ribs. Minor changes can be made without new tooling; major changes may require a mold modification. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 500 pieces for existing tooling and 1000 pieces for new molds. However, we can discuss lower quantities for prototyping or evaluation purposes. -
Q: What certifications do you hold?
A: We are certified under TS16969 (equivalent to IATF16949). All production is controlled under this quality system, and we can provide PPAP documents upon request. -
Q: What is the typical lead time for samples and mass production?
A: Sample lead time is 2–3 weeks, and mass production takes 4–6 weeks after sample approval. Rush orders can be expedited on a case-by-case basis. -
Q: Do you offer export packaging for international shipping?
A: Yes, we vacuum-seal each bracket and pack in anti-static foam trays inside export-grade cartons. Packaging can be customized to meet your ERP or barcode requirements. -
Q: Can you ship to Singapore directly?
A: Certainly. We ship to Singapore and any other destinations worldwide via sea or air, with full documentation and customs clearance support.
