General Purpose Three-Phase Motor

The Baldor Electric EM3550 is a 1 1/2 HP three-phase motor built for continuous-duty industrial applications. It delivers 3550 RPM nameplate speed from a NEMA 56 frame with rigid-base mounting. The motor operates on 208-230/460V AC at 60 Hz and is rated for 40 degrees C maximum ambient temperature. It suits workshops and machinery requiring dependable fixed-speed rotation.

Totally Enclosed Fan-Cooled Enclosure

A totally enclosed fan-cooled design protects windings from dust and moisture while allowing all-angle mounting flexibility. The shaft rotates both clockwise and counter-clockwise to match driven equipment needs. Class F insulation and a 1.15 service factor support sustained operation under load. The rigid base provides stable footing on machine frames or mounting plates.

Ready for 208V Supply Networks

The motor is usable at 208V as well as 230V and 460V connections with full-load currents of 3.8 and 1.90 amps respectively. No thermal protection is fitted so external overload devices must be supplied by the installer. Continuous duty cycle and NEMA Design B torque characteristics suit constant-speed pumps, fans and conveyors. Wiring follows standard three-phase terminal arrangements.

Questions about this item

What voltage range does the 3-phase 1 1/2 HP motor accept, and what current does it draw at full load?

The motor runs on 208-230/460V AC at 60 Hz and draws 3.8 amps at 208-230V or 1.90 amps at 460V under full load.

Which NEMA frame size and mounting style does the rigid-base motor use?

It uses a 56 frame with a rigid base and can be mounted at any angle.

How is the motor wired for 208 V versus 460 V, and what common mistake should be avoided?

Reconfigure the terminal links to match the supply voltage; the motor is usable at 208 V but not at 200 V, so verify the line voltage before connecting.
