Rated at 3520 RPM with a service factor of 1.15, this NEMA Premium (IE3) motor delivers 4.35 ft-lb of full-load torque while operating at 115/208-230V, 60Hz. Dual-voltage compatibility simplifies installation across North American facilities, supporting flexible deployment in HVAC systems, pumps, compressors, and general industrial machinery. Key electrical specifications include a rated current of 23.1/11.5 Amps (high/low voltage), nominal efficiency of 85.5%, and a power factor of 0.97. The motor meets NEMA Design L standards and is tropicalized for reliable performance in humid or corrosive environments. Mechanical robustness is ensured by 6205-ZZ shielded ball bearings on both drive-end (DE) and non-drive-end (NDE) sides. The motor features a removable foot design for easy mounting and includes a 650µF/165V start capacitor and 115µF/250V run capacitor for smooth acceleration and reduced inrush current. A 1/2" NPT cable entry simplifies wiring, and the continuous duty rating supports operation at altitudes up to 1000 meters.
