Three-Phase General Purpose Motor

This Baldor-Reliance motor delivers 3 HP at 3,450 RPM in a 143TC frame. It runs on 208-230/460V AC three-phase power at 60 Hz. The C-face mounting suits direct-coupled pumps, gearboxes and conveyors in industrial plants.

Thermals Noise and Power Draw

Class F insulation and a 1.15 service factor handle continuous duty up to 40 °C ambient. Full-load current is 7.2 A at low voltage and 3.6 A at high voltage. Nominal efficiency reaches 86.5 percent. Totally enclosed fan-cooled construction keeps windings clean without external ducting.

Upgrade Path and Fit

The steel frame and ball bearings replace open drip-proof units where dust or moisture shorten life. Dual-voltage wiring simplifies stock for 208 V, 230 V or 460 V panels. No built-in thermal protection means the starter must provide overloads. CSA and UR listings cover North American codes.

Questions about this item

How do I install the 143TC frame motor and which wiring step is often missed?

Bolt the C-face to the driven equipment, connect three-phase supply to the nine leads for either 208-230 V or 460 V operation, and verify rotation is CW/CCW as required; the step often missed is confirming the voltage jumper links match the supply before energising.

What maintenance will the motor need and when should the bearings be replaced?

The ball bearings are the primary wear item; plan to inspect and relubricate them at regular intervals and replace them when vibration or noise increases beyond normal levels.

What is the first limit reached during continuous full-load operation?

The 40 °C maximum ambient temperature combined with the 1.15 service factor defines the thermal limit; sustained overload or higher ambient will trip the winding insulation class F boundary first.
