Baldor EM3554T-G 1.5 HP TEFC 3-Phase Electric Motor 208-230/460V 1760 RPM

The Baldor EM3554T-G is a premium efficiency three-phase AC motor designed for HVAC and general industrial applications requiring variable frequency drive (VFD) compatibility. This 1.5 HP motor features factory-installed AEGIS shaft grounding ring technology (denoted by the "-G" suffix) that protects bearings from damaging electrical currents commonly generated in VFD applications.

Key Specifications:

• Power output: 1.5 HP at 60 Hz
• Multi-voltage operation: 208V, 230V, or 460V
• Full load amps: 4.64A @ 208V, 4.6A @ 230V, 2.3A @ 460V
• Speed: 1760 RPM (4-pole, 1800 synchronous RPM)
• NEMA 145T frame with steel construction
• TEFC (Totally Enclosed Fan Cooled) enclosure
• Premium efficiency rated at 86.5% @ 100% load
• Service factor: 1.15 for overload capability

Advanced Features:

• Factory-installed AEGIS bearing protection ring prevents premature bearing failure from VFD-induced shaft currents
• Class H insulation system with Class B temperature rise meets NEMA MG1 Part 31.4.4.2 for inverter duty
• NEMA Design B with continuous duty rating
• Ball bearings with Polyrex EM grease (-20°F to +300°F)
• 7/8" keyed output shaft with 2-1/4" shaft length
• Rigid foot mounting (standard)
• Maximum ambient temperature: 40°C

Applications: Ideal for HVAC blowers and fans, pump motors, compressors, conveyors, machine tools, and other general purpose applications using variable frequency drives. The AEGIS shaft grounding technology makes this motor fully VFD-ready while the premium efficiency design reduces energy consumption over extended operating periods.
