Three-Phase TEFC Motor
The Baldor Electric EM3550T is a 1-1/2 HP three-phase AC motor built for continuous duty in industrial and commercial settings. Its totally enclosed fan-cooled enclosure protects internal components while the 143T steel frame provides rigid base mounting. The motor operates on 208-230/460V AC at 60 Hz with full-load currents of 3.8 and 1.9 amps.
Upgrade From Single-Phase Or Lower Output
This motor replaces single-phase units when three-phase power is available and higher efficiency is required. The jump is worthwhile for equipment needing 84 percent nominal efficiency, a 1.15 service factor and Class F insulation rated for 40 degrees C ambient. It also suits replacements where CW/CCW rotation flexibility and ball bearings are specified.
Capacity And Headroom
The 3500 RPM nameplate speed delivers consistent torque for pumps, fans and conveyors within the 3001-3600 RPM range. CSA, CSA EEV and UR listings confirm compliance for regulated installations. Thermal protection is not included, so external overload devices must be supplied by the installer. The 36.75 weight figure aids mounting planning.

Questions about this item
What frame size and mounting type does the 143T motor require?
The motor uses a 143T frame with a rigid base mounting type.
How do I wire the three-phase motor for 208-230V or 460V supply?
Connect the nine leads for low voltage 208-230V or high voltage 460V per the nameplate diagram; verify rotation is CW/CCW as needed.
When should the ball bearings be inspected or replaced?
Inspect bearings at regular intervals; the motor runs at 3500 RPM with Class F insulation and 1.15 service factor under continuous duty.
