Industrial three-phase motor

The Baldor Electric EM3211TA is a 3 HP three-phase AC motor built for general-purpose industrial use. It operates at 1760 RPM with a 182T frame and an open drip-proof enclosure. The motor runs on 208-230/460V AC at 60 Hz and is rated for continuous duty in ambient temperatures up to 40 degrees C.

Steady-state thermal behaviour

With a 1.15 service factor and Class F insulation, the motor is designed to sustain its rated load without overheating during prolonged operation. Auto thermal protection reacts if internal temperatures exceed safe limits, while the 89.5 percent nominal efficiency reduces waste heat. Full-load current sits at 8.8 amps on low voltage and 4.4 amps on high voltage, giving predictable draw for circuit planning.

Steel frame and rigid mounting

The steel frame uses a closed-base, rigid-base mounting pattern that bolts directly to machinery foundations. Ball bearings support the shaft for bidirectional rotation, allowing CW or CCW operation as wired. The enclosure carries CSA, CSA EEV and UR markings, confirming compliance with North American safety standards for the environments where this frame size is typically installed.

Questions about this item

How much heat does the 3 HP motor generate when running continuously at its 40 °C maximum ambient temperature?

The motor is rated for continuous duty at up to 40 °C ambient with Class F insulation and a 1.15 service factor, so it dissipates its losses within that thermal envelope without additional cooling.

What voltage supply and starter gear must I already have to run this 208-230/460 V three-phase motor?

You need a three-phase supply of either 208-230 V or 460 V at 60 Hz plus a compatible three-phase starter or VFD rated for at least 8.8 A at low voltage or 4.4 A at high voltage.

Will the 182T frame and rigid base match the mounting pattern on my existing 182T fan assembly?

Yes, the motor uses the standard NEMA 182T frame with a rigid base, so it bolts directly to any equipment drilled for an 182T footprint.
