Is Large Industrial Motor Technology Standing Still? Not Anymore.

For decades, improvements in high-power motors were incremental: better cooling systems, refined calculation tools, and test-to-model adjustments. Real breakthroughs? Rare.

But things are changing. Permanent magnet motors are gaining ground, delivering benefits that go far beyond nameplate efficiency. Globally, adoption is varied. In some regions, the technology is spreading and accelerating. In others, industry is more hesitant or still learning.

At Wolong Electric America, we’re proud to be at the forefront of this shift, successfully implementing permanent magnet (PMSM) technology in medium-voltage, high-power motors.

Our challenge is clear:

- Clarify technical questions about this new technology.

- Explain the differences between Induction (IM) and Permanent Magnet (PMSM) motors.

- Share application details and protection considerations.

All this to help customers make informed decisions and take advantage of higher efficiencies across load ranges, lower thermal stress, and longer lifetime performance.
