Baldor Electric
Baldor Electric CEM3555T 2 HP 145TC three-phase machinery motor
A 2 HP three-phase motor in a 145TC frame, totally enclosed fan cooled for 85.5 % nominal efficiency at 3490 rpm
- 2 HP output drives demanding machinery
- 3490 rpm nameplate speed for high-speed applications
- 5% nominal efficiency reduces energy consumption
- 230/460 V dual voltage suits varied power supplies
- 145TC C-face frame enables direct mounting
Three-phase motor for general machinery
The Baldor Electric CEM3555T is a 2 HP three-phase motor built for continuous duty in industrial equipment. Its totally enclosed fan-cooled design protects internal components from dust and moisture. The steel frame and Class F insulation suit demanding shop environments.
Replaces failed 145TC frame units
This motor fits existing 145TC mounting patterns and runs at 3490 rpm nameplate speed on 230/460V AC at 60 Hz. The 1.15 service factor provides a margin above rated load. The upgrade is worth it when the old unit lacks CSA and UR markings or shows efficiency below 85.5 percent.
Direct C-face mounting simplifies install
The C-face flange bolts straight to gearboxes or pumps without a separate coupling bracket. Ball bearings arrive pre-lubricated for the 40 degrees C max ambient rating. Common issues are wiring the dual-voltage leads for the wrong supply and skipping alignment checks that over-load the 5/2.5 A full-load current.

Questions about this item
What 145TC frame dimensions must the mounting surface match for this motor?
The motor uses a 145TC C-face frame with 2 HP output, 3490 rpm nameplate speed, 230/460 V AC three-phase supply at 60 Hz, and a steel frame built for continuous duty in ambient temperatures up to 40 °C.
Which wiring step on the dual-voltage terminal block is most often missed during installation?
The motor runs on 230/460 V AC three-phase power; the installer must link the nine leads for the chosen voltage — 5 A full-load at 230 V or 2.5 A at 460 V — and verify CW/CCW rotation before coupling the load.
When should the ball bearings be re-greased or replaced on this unit?
With Class F insulation, 1.15 service factor, 85.5 % nominal efficiency and continuous-duty rating, the sealed ball bearings typically require re-greasing or replacement after extended operation near the 40 °C ambient limit; follow the manufacturer's lubrication interval for the specific bearing size.
