Choosing between two very different industrial motors can feel like comparing pumps to gearboxes. The Baldor-Reliance VEM3558T is a three-phase motor bundled with a Dodge Quantis speed reducer, while the Single Phase 5HP SPL Air Compressor Electric Motor is a dedicated single-phase workhorse for compressor duty. Your decision comes down to the electrical service you have and the speed you need to deliver.
Quick verdict
If you need a right-angle speed reducer for an industrial application, the Baldor-Reliance package is the complete solution. If you need a straightforward motor to repower an air compressor, the SPL motor is the lower-priced option.

Product notes
Baldor-Reliance VEM3558T Industrial Electric Motor + Dodge Quantis Speed Reducer
The Baldor-Reliance VEM3558T is more than a motor; it's a drive package. The Super-E motor runs at 1725 RPM on 208-230/460 V three-phase power, and the coupled Dodge Quantis right-angle helical-bevel reducer increases torque with a 5.65:1 ratio and a 1019 in-lb maximum output torque. That makes it a strong choice for a conveyor, agitator, or any application that needs high torque at a lower output speed. The TEFC enclosure also protects the motor from dust and splashes, which is useful in rougher shops. The limitation is upfront: at $700, it's the more expensive option by a wide margin, and it requires a three-phase electrical supply. It's also listed as new open box, so inspect the package before you commit.
Single Phase 5HP SPL Air Compressor Electric Motor
The Single Phase 5HP SPL Air Compressor Electric Motor is built for exactly one job: repowering an air compressor on a 230V single-phase circuit. It delivers 5HP at 3450 RPM, spins on a 5/8\" keyed shaft, and supports both CW and CCW rotation, with the factory set to CCW. That dual-rotation flexibility is a welcome touch when you're swapping out an old motor. At $141.88, it's the lower-priced choice. The limitation is the open drip-proof (ODP) enclosure, which suits clean, dry areas but not dusty or wet locations.
Final choice by use case
Choose the Baldor-Reliance VEM3558T package if you need the integrated Dodge Quantis reducer to deliver higher torque at a lower output speed. Choose the Single Phase 5HP SPL Air Compressor Motor if you need a keyed-shaft motor to repower an air compressor and want to keep the purchase price down.
