For Purchasing Managers, Technical Directors & Operations Leaders who need reliable, cost‑effective three‑phase motors for industrial automation, we deliver factory‑direct OEM/ODM solutions with fast delivery, strict quality assurance, and full compliance (CE, ISO 9001, RoHS).
Both configurations are the backbone of modern three‑phase motor drives. Selecting the right one can reduce energy consumption by up to 12% and lower maintenance costs by 18%.
| Parameter | Delta Connection | Wye (Star) Connection |
|---|---|---|
| Starting Torque | Higher (≈ 30% more) | Lower, smoother start |
| Current per Phase | ≈ 1.73 × Line Current | Equal to Line Current |
| Voltage Utilization | Full line voltage across windings | √3 × Phase voltage (lower stress) |
| Typical Applications | High‑torque pumps, compressors, conveyors | HVAC fans, lift motors, general‑purpose drives |
Case 1 – Automotive Assembly Line (USA): Switched from imported wye‑motor to our custom delta‑rated 15 kW units. Result: 11% energy saving, $45 k annual cost reduction, and 30% faster start‑up.
Case 2 – Medical Device Manufacturing (California): Required CE‑marked wye motors with low harmonic distortion. Our OEM solution delivered 0.5 % THD, meeting FDA‑GMP standards and eliminating a costly redesign.

“Switching to Xinchangda’s delta‑configured motors cut our line‑start time by 40% and saved $30 k in the first year.” – John M., Operations Manager, Midwest Manufacturing
“The OEM wye design met all UL and FDA requirements without extra testing costs.” – Linda S., Procurement Lead, MedTech Solutions
All products are backed by CE, ISO 9001, RoHS, and FCC certifications, ensuring compliance with US import regulations.
Delta connects the three windings in a closed loop, delivering higher starting torque and line voltage across each winding. Wye (star) connects one end of each winding to a common neutral point, providing lower current per phase and smoother start‑up, ideal for energy‑efficient applications.
Yes. Our R&D team can produce NEMA‑compatible frames, 208‑V, 230‑V, 460‑V options, and tailor winding configurations (delta or wye) to meet your exact load profile.
Standard production is 2‑4 weeks after design approval and deposit. Expedited 1‑week service is available for an additional 10% surcharge.
All motors ship with CE, UL, FCC, and RoHS certificates, accompanied by a full test report. We also provide customs documentation (COO, commercial invoice) in English.
Yes. Our 24/7 support line (+86 131 2825 6415) and dedicated US liaison provide troubleshooting, spare‑part sourcing, and on‑site commissioning assistance.
Limited‑time offer: **Free 3‑Month Warranty** and **Sample Motor shipped at no cost** for orders placed before 31 May 2026.

Mark T., Procurement Manager, GreenTech Energy
“The delta‑configured motors arrived in 18 days, met all UL standards, and reduced our startup power surge by 22%. Highly recommend Xinchangda for fast, reliable OEM service.”
Susan L., Technical Director, AeroParts USA
“We needed a wye motor with strict vibration limits for our CNC machines. Xinchangda delivered a custom‑tuned solution that cut vibration by 30% and extended bearing life.”
David K., Operations VP, Midwest Food Processing
“Their ISO 9001‑certified production line gave us confidence, and the free 3‑month warranty saved us $12 k in unexpected repairs.”
