Baldor Electric EM3120T Three-Phase Motor 1 1/2 HP 143T

SKU CH-H96J-Z5H8J

Three-phase general-purpose motor delivers 1.5 HP at 3,490 rpm in a 143T steel frame with 84 percent nominal efficiency

  • Runs at 3490 rpm for high-speed output
  • 84 percent nominal efficiency reduces energy cost
  • Dual voltage 208-230/460 V fits multiple supplies
  • 15 service factor handles overload conditions
  • Open drip-proof enclosure suits clean, dry environments

Industrial Three-Phase Motor

The Baldor-Reliance EM3120T is a 1 1/2 HP general-purpose motor built for continuous industrial duty. It suits OEMs and maintenance teams needing a reliable 143T frame replacement for pumps, fans or conveyors. Its open drip-proof enclosure fits clean, dry indoor environments. Buyers who need a totally enclosed or washdown-rated unit should look elsewhere.

Steel Frame with Rigid Base

A steel frame and rigid base mounting provide secure, vibration-resistant installation on flat surfaces. Dual-voltage windings (208-230/460 V AC) simplify wiring across common plant supplies. Ball bearings support the shaft for smooth rotation in either direction. The design lacks a brake or encoder, so applications requiring precise positioning or holding torque are not served.

Efficient 3490 RPM Operation

Rated at 84 percent nominal efficiency, the motor draws 4.0 A at low voltage and 2.0 A at 460 V under full load. Class F insulation and a 1.15 service factor allow sustained operation up to a 40 °C ambient. No internal thermal protection is fitted, so external overload devices are required. CSA, CSA EEV and UR markings confirm compliance for North American installations.

Questions about this item

What voltage range does the three-phase 208-230/460 V supply support at 60 Hz?

The motor runs on 208-230 V or 460 V three-phase power at 60 Hz, drawing 4.0 A at the lower voltages and 2.0 A at 460 V.

What frame size and mounting style does the 143T steel frame require?

It uses a NEMA 143T rigid base with steel construction, so the mounting surface must match the 143T bolt pattern and support the motor weight.

How do you set the dual-voltage connections and confirm rotation before coupling the load?

Wire the nine leads for either 208-230 V or 460 V per the nameplate diagram, then jog the motor to verify CW/CCW rotation before final alignment.
