Wolong Electric America Stands by Its EMR-Bulldozer for High-Efficiency in Data Centers

Wolong Electric America has highlighted its EMR-Bulldozer Series “a ferrite-assisted synchronous reluctance integrated drive motor” made for high-efficiency, powerful performance, and long-term reliability in harsh data center facility environments. Wolong Electric America claims that the EMR-Bulldozer Series has efficiency equivalent to IE5, the highest recognized international standard as of now. The product’s motors deliver high power density and energy savings, making them suitable for rigorous fan, pump, compressor, and conveyor applications in data center facilities.

“The EMR-Bulldozer features an integrated drive system that supports variable speed loads across a wide operational range, from low speed to high rated speeds, and even offers an extended constant power control range above rated speed. This flexibility enables precise speed regulation and accurate low-speed control, making the motors particularly suitable for environments that require strict performance standards and low noise operation.”

The motors come in standard NEMA frames (184T to 286T) along with 4 or 6 pole options, horsepower ratings between 3 to 50 HP, and speeds of either 1200 or 1800 RPM. The bulldozer is approved by UL, cUL, and CSA with its operation at 480V, making sure it is compliant with North American safety standards.

“The motors are 3-5% more efficient than traditional induction motors when operating at 25-100% load in VFD applications, resulting in rapid energy cost payback. The innovative rotor design, utilizing non-rare earth ferrite compound permanent magnets, reduces energy losses by 40% and lowers operational noise. This technology also ensures cooler running core, stator, and bearing temperatures, which extends the lifespan of the motor and reduces maintenance requirements. The motors are engineered for easy drop-in replacement in retrofit projects, matching the size of standard induction motors and eliminating the need for mechanical modifications.”
