Three-Phase Low-Voltage Electric Motors
Three-phase low-voltage electric motors are the industry standard for industrial power and performance.
Operating between 208 V and 575 V, these motors provide balanced torque, smooth startup, and superior efficiency for continuous-duty applications such as pumps, conveyors, compressors, and processing equipment.
Available in ODP, TEFC, and Explosion-Proof (TEXP) configurations, all models meet NEMA Premium® efficiency standards and are engineered for compatibility with variable-frequency drives (VFDs) and modern control systems.

Why Three-Phase Motors Dominate Industry
Balanced Power: Equal current in all phases delivers smoother torque and minimal vibration.
Efficiency: Lower current per phase reduces heat and energy loss.
Scalability: Supports horsepower from 1 HP to 500 HP+.
Reliability: Ideal for continuous operation under demanding loads.
VFD-Ready: Works seamlessly with modern variable-frequency controls.
These advantages make three-phase motors the default choice for industrial plants, manufacturing lines, and mechanical systems worldwide.
Enclosure and Frame Options
Frame materials include Cast Iron for rigidity, Stainless Steel for corrosion resistance, and Fabricated Steel for OEM customization.
Mounting Configurations
Mount Typical Use
Foot Mount Fixed horizontal installations.
C-Face Mount Pump and gearbox coupling.

Three-phase motors are the backbone of production, utility, and processing operations across North America.
Efficiency and Standards
All models comply with:
NEMA MG-1 and IEEE 112 test standards.
CSA and UL certifications (where applicable).
Inverter-Duty insulation for VFD operation.
Energy-efficient designs can reduce operating costs by up to 10 – 15 % over older IE2-level models.
