Powering with Permanent Magnets, Leading the Oil & Gas Future

Product Overview

The direct-drive 3-phase permanent magnet synchronous motor for pump stations is designed to meet the demands of long-cycle continuous operation and frequent operating-condition fluctuations. It emphasizes comprehensive engineering performance featuring “low-speed high-torque, high efficiency, low losses, and reduced maintenance.” By using high-performance permanent magnet materials and optimized electromagnetic design, it can stably deliver high torque even in low-speed ranges, enabling pump station systems to move away from the traditional multi-stage transmission path of “high-speed motor + gearbox,” reducing mechanical losses and failure points, and improving overall system reliability.

In terms of control and operation, the motor can be deeply coupled with a VFD drive system to achieve fine regulation of speed, torque, and key process parameters, meeting pump station control requirements under different heads, different media, and different operating strategies. With excellent efficiency and power factor performance, it effectively reduces reactive power in the line and system heat generation, minimizing energy waste and providing more sustainable energy-saving benefits and more stable power-supply economics for pump stations.

Compared with traditional solutions, the direct-drive/quasi-direct-drive permanent magnet system features a simpler structure, lower maintenance workload, and more controllable probability of unplanned downtime, making it especially suitable for high-standard configurations in pump station efficiency-upgrade retrofits and new-build projects. Yuheng Dynamics can provide customized parameter matching, structural selection, and coordinated control design based on customer operating conditions and interface constraints, and also supports on-site commissioning and operation optimization, ensuring energy savings and stability continue to deliver value in long-term operation.
