Us Motors U32E1A14CR 1.5 Hp Tefc Ac Motor 3450 Rpm

Product Description

The US MOTORS U32E1A14CR is a three-phase, energy-efficient AC motor built for general-purpose industrial and commercial applications. Rated at 1.5 HP and 3450 RPM, it runs on 208 to 230 volts or 460 volts at 60 Hz, giving installers flexibility across single and dual-voltage systems. The totally enclosed fan-cooled (TEFC) enclosure protects the motor from dust, moisture, and debris, making it suitable for demanding environments. Full-load efficiency is rated at 88.20 percent with a 1.15 service factor, and the Class B insulation supports sustained operation under normal thermal loads. The 143TC frame with C-Face mount is the standard configuration for direct-coupled pump, fan, and compressor drives installed by licensed mechanical contractors and industrial maintenance technicians.

This motor is suited for general-purpose applications in light industrial, commercial HVAC, and process equipment settings. The reversible rotation allows flexible installation orientation without requiring a separate motor variant. The C-Face mount integrates directly with gearboxes, pumps, and blowers that accept the 143TC C-Face bolt pattern. Full-load amperage is 4.6 to 4.3 amps at 208 to 230 volts and 2.1 amps at 460 volts, allowing proper wire sizing and overload protection selection per NEC guidelines. Single-speed operation keeps control wiring straightforward for standard contactor or starter setups.

Installation Notes

Installation should be performed by a qualified electrician or licensed mechanical contractor. Disconnect and lockout all power before mounting or wiring the motor. Wire sizing, overload protection, and grounding must comply with NEC requirements for the nameplate voltage and amperage. Verify rotation direction before coupling to driven equipment, and ensure the mounting surface and coupling alignment meet the equipment manufacturer specifications.
