Powering with Permanent Magnets, Leading the Oil & Gas Future

Product Overview

The semi-direct-drive permanent magnet synchronous motor for beam pumping units is developed for long-term continuous oilfield operation, focusing on core on-site needs including “high efficiency, low losses, and reduced maintenance.” Through coordinated optimization of the electromagnetic scheme and structural system, the motor maintains smooth output even under low-speed, heavy-load conditions, reducing shock loads and vibration risks and providing a more reliable power foundation for pumping equipment.

Compared with the traditional solution of “motor + belt + reducer/transmission,” the semi-direct-drive structure significantly reduces transmission stages and the number of wear parts, effectively lowering hidden O&M costs caused by belt slippage, tensioning maintenance, and alignment commissioning, while improving overall system energy efficiency, making energy-saving benefits easier to realize and more sustainable.

The motor can be deeply matched with a VFD control system to enable fine adjustment of pumping unit speed and motion curves, supporting fast response and optimization under changing field conditions; while ensuring stable start/stop performance, it reduces unnecessary energy consumption and mechanical wear, improving controllability and stabilizing per-well production.

Overall, the semi-direct-drive permanent magnet synchronous motor provides a more efficient, compact, and reliable drive-upgrade pathway for oil & gas artificial lift equipment, and is an important direction for improving efficiency, reducing energy consumption, lowering maintenance, and enhancing long-term stable operation.
