Baldor Electric CEM3550T Three-Phase General Purpose Motor 1 1/2 HP 143TC
Three-phase totally enclosed fan-cooled motor delivering 1 1/2 HP at 3500 rpm in a 143TC C-face frame with 84 percent nominal efficiency
- 84 % nominal efficiency reduces energy consumption
- 15 service factor handles peak loads reliably
- Totally enclosed fan-cooled design protects against dust and moisture
- Dual-voltage 230/460 V AC suits multiple supply configurations
- C-face 143TC frame simplifies direct coupling installation
Application & User
This Baldor-Reliance CEM3550T is a three-phase general-purpose motor rated at 1 1/2 HP with a 143TC C-face frame. It suits OEMs and maintenance teams replacing failed units on pumps, fans, conveyors or gearboxes where a standard NEMA footprint and CW/CCW rotation are required.
Critical Specification
The motor runs at 3500 rpm nameplate speed on 230/460 V AC, 60 Hz supply, drawing 3.8 amps at 230 V or 1.9 amps at 460 V full load. Voltage and frequency must match the site supply exactly or the motor will not develop rated torque and may overheat.
Installation Notes
The 143TC C-face with 1.15 service factor bolts directly to NEMA-matched reducers or pump housings using four through-bolts; no base shimming is needed. Common issues are wiring the nine leads for the wrong voltage, neglecting external overload protection since thermal protection is not built in, and exceeding the 40 °C ambient limit in confined cabinets.

Questions about this item
How does the 3500 rpm nameplate speed translate when the motor is under load?
At full load the motor runs at its rated 3500 rpm, delivering 1 1/2 HP continuously with a 1.15 service factor for occasional overload.
What does the 230/460 V dual-voltage rating mean for wiring?
The motor can be connected for either 230 V or 460 V three-phase supply; full-load current is 3.8 A at 230 V and 1.9 A at 460 V.
What mounting provisions does the 143TC frame provide?
The 143TC frame includes a C-face flange with standard bolt pattern and a keyed shaft for direct coupling to pumps or gearboxes.
