en.Wedoany.com Reported - On May 6, 2026, Wolong Electric USA launched the Quantum 500 frame medium-voltage motor in the North American market, expanding its Quantum™ platform. Designed for demanding applications in oil and gas, petrochemical, mining, pumping, and compression equipment, the motor aims to replace traditional designs by enhancing power density, structural rigidity, and installation flexibility.

The Quantum 500 frame medium-voltage motor modernizes the platform, aligning frame sizes, ratings, and mounting dimensions with current industry standards, enabling direct replacement of existing equipment of the same brand. Structurally, the motor's natural frequencies are at least 15% away from the operating range, reducing resonance risk. The shaft diameter has been increased from 5.23 inches to 6.8 inches, and the bearing center distance has been shortened, improving shaft stiffness and ensuring reliable operation under rigid base, flexible skid, and other mounting conditions.

The motor also offers high flexibility: the terminal box orientation can be switched on-site (F1/F2) without returning to the factory. Select models support deep flange cantilever mounting, suitable for applications without a base, such as screw compressors. The motor has a rated voltage below 7 kV, offers WPI/WPII protective enclosures, a bearing design life exceeding 100,000 hours, and an insulation system with an expected life of 30 years.

Wolong Electric USA, headquartered in Houston, Texas, is dedicated to providing efficient and reliable motor solutions for the industrial sector.
