Baldor-Reliance EM3583T 3-Phase Motor 1 1/2 HP 143T Frame

SKU CH-D9DB-6R54A

Three-phase general-purpose motor delivers 1.5 HP at 3500 rpm in a 143T cast-iron frame with 208-230/460 V operation and 84 % nominal efficiency

  • TypeMotors
  • 84% nominal efficiency reduces energy consumption
  • 15 service factor handles peak loads
  • Cast iron frame withstands harsh environments
  • 208-230/460 V AC suits multiple power supplies
  • 3500 rpm nameplate speed for high-speed applications

Motor purpose and fit

This Baldor-Reliance EM3583T is a three-phase general purpose motor rated at 1 1/2 HP in a 143T frame. It suits industrial equipment that needs continuous duty at 3500 rpm nameplate speed. Buyers who need a different horsepower, a single-phase supply or a non-standard frame size should look elsewhere.

Electrical supply checks

Verify that your installation provides 208-230/460 V AC at 60 Hz three-phase power before ordering. The motor draws 3.8 A at the lower voltage and 1.9 A at 460 V with a 1.15 service factor. Ensure your starter, overload protection and wiring are sized for these full-load currents.

Thermal and mechanical behaviour

The totally enclosed fan cooled cast-iron frame operates in ambient temperatures up to 40 degrees C with Class F insulation and no built-in thermal protection. Nominal efficiency is 84 percent at continuous duty. Ball bearings support bidirectional shaft rotation and the rigid base mounting keeps vibration low during normal operation.

Questions about this item

Does the EM3583T ship with a mounting base or do I need to buy one separately?

The motor has a rigid base built into the cast-iron frame, so no separate base is required for standard foot mounting.

How do I decide between the 208-230 V and 460 V connection on this 1 1/2 HP unit?

The motor is dual-voltage; wire it for 208-230 V if your supply is in that range, or for 460 V if you have a 460 V three-phase service.

What does the 84 percent nominal efficiency mean for daily operation at 3500 rpm?

At rated load the motor delivers 84 percent of input power as shaft output, keeping losses low during continuous duty cycles.
