Industrial Three-Phase Motor

The Baldor Electric EM3554T is a 1-1/2 HP general-purpose AC motor built for continuous-duty industrial applications. It operates at 1760 RPM with a 145T frame and Totally Enclosed Fan-Cooled enclosure. Rated for 208-230/460V at 60 Hz, it suits conveyor, pump and fan drives in factories and processing plants.

Upgrade From Single-Phase Or Lower-HP Units

This motor replaces single-phase models where three-phase power is available, delivering smoother torque and higher efficiency. The step up is worth it when duty cycles demand continuous operation at 40 °C ambient and a 1.15 service factor. It is usable at 208 V but not at 200 V, so supply voltage must be confirmed before installation.

Suits Rigid-Base Mounting In Fixed Equipment

The rigid base and all-angle mounting position fit stationary machinery with standard 145T footprints. Buyers needing C-face or D-flange mounting, thermal overload protection, or a different frame size should look at alternative motor configurations. The 48 weight figure and closed-base construction suit permanent installations rather than portable tooling.

Questions about this item

What frame size and mounting type does the 145T rigid-base motor require?

It uses a NEMA 145T frame with a rigid-base mounting pattern; bolt it to a flat surface that matches the 145T footprint.

How do I wire the dual-voltage 208-230/460 V motor correctly?

For 208-230 V connect the leads in parallel; for 460 V connect them in series, and verify rotation is CW/CCW as needed.

Which components will need periodic replacement on this TEFC motor?

The fan-cooled enclosure relies on external fan and bearings; plan to inspect and replace bearings and the cooling fan over time.
