Choosing an industrial motor isn't just about power. You also have to decide between a standalone motor and a motor already paired with a speed reducer, consider what enclosure protects the windings from dust and moisture, and weigh the total cost of the setup. The two Baldor-Reliance 3-phase AC options here - the CNM3457 and the VEM3558T with a Dodge Quantis speed reducer - take different paths to the same goal of reliable industrial rotation.
Quick Verdict
The CNM3457 is the simpler 3-phase motor with a TENV enclosure that handles heavy dust, dirt, and light moisture. The VEM3558T + Dodge Quantis is the integrated gearmotor solution, adding a right-angle helical-bevel reducer to a TEFC motor. The two setups sit $425 apart, and that difference buys you a matched motor-and-reducer package with a fan-cooled motor.

Where Each Product Wins
- Baldor-Reliance CNM3457 is the better fit when you want a standalone motor with a TENV enclosure and a 3450 RPM base speed for direct-drive, single-speed applications.
- Baldor-Reliance VEM3558T + Dodge Quantis is the better fit when you need a right-angle speed reducer, a TEFC motor, and a matched motor-and-reducer package in one purchase.
Product Notes
Baldor-Reliance CNM3457 3-Phase General-Purpose Industrial AC Electric Motor
The CNM3457 is a 3-phase TENV motor rated for 60 Hz and 208-230/460 V input. Its 3450 RPM base speed makes it a good match for single-speed setups. The totally enclosed non-ventilated housing is designed to handle environments with heavy dust, dirt, and light moisture, so it holds up well in a gritty shop or production floor. This is the motor to pick when you want a clean, direct-driven approach and don't need a gearbox in the same purchase. The main limitation is that the listing is for the motor itself, so you'll need to source any speed reduction separately if your application requires it.
Baldor-Reliance VEM3558T Industrial Electric Motor + Dodge Quantis Speed Reducer
This package combines a Baldor-Reliance motor with a Dodge Quantis right-angle helical-bevel speed reducer. The reducer delivers a maximum output torque of 1019 in-lbs and a 5.65:1 ratio, while the motor's TEFC enclosure provides fan-cooled protection for demanding conditions. The 3-phase unit is rated for 60 Hz and 208-230/460 V input, and the motor and reducer are paired as a single setup. If your driven equipment needs reduced speed and increased torque at a right angle, this package saves you the hassle of matching a separate gearbox. The limitation is that it's best used where right-angle speed reduction is actually needed; for direct-drive jobs, the added gearbox may be more than you require.
Final Choice by Use Case
If your industrial motor job is a straightforward 3-phase application that doesn't need gear reduction, the CNM3457 is the pragmatic pick. If you need right-angle gear reduction with meaningful output torque and prefer to buy the motor and reducer together, the VEM3558T + Dodge Quantis package is the better match.
