Buying an industrial motor comes down to two questions: the power available in your shop and the machine it needs to spin. The Baldor-Reliance CNM3457 and the GARVEE 5HP SPL Air Compressor Motor are both 3450 RPM motors, but they are built for opposite sides of that decision. This head-to-head will help you match the right one to your setup.
Quick Verdict
If you need a low-horsepower motor built for dusty and lightly moist industrial areas, the Baldor-Reliance CNM3457 is the safer choice. If you need a direct replacement for an air compressor, the GARVEE 5HP SPL is the more practical pick.
Comparison
| Product | Price | Price bar | Phase | Horsepower | Enclosure |
|---|---|---|---|---|---|
| Baldor-Reliance CNM3457 | $275.00 | Three-phase | 0.33 HP | TENV | |
| GARVEE 5HP SPL Air Compressor Motor | $128.79 | Single-phase | 5HP | ODP |
The price gap is $146.21, with the GARVEE coming in lower. The Baldor is a three-phase 0.33 HP motor with a TENV enclosure. The GARVEE is a single-phase 5HP motor with an ODP enclosure. Before you decide, think about whether your shop can supply the required voltage and whether the motor's enclosure matches the working environment.
Where Each Wins
- The Baldor-Reliance CNM3457 wins when you need a non-ventilated motor for a single-speed industrial job in a dirty or dusty space.
- The GARVEE 5HP SPL wins when you need a compressor-specific motor with reversible rotation for a straightforward swap.
Product Notes
Baldor-Reliance CNM3457 3-Phase General-Purpose Industrial AC Electric Motor
This Baldor-Reliance motor pairs a TENV enclosure with a modest 0.33 HP output, so it is not going to power a large air compressor or a heavy industrial machine. What it does do is keep dust, dirt, and light moisture away from the internal windings, which is a genuine advantage in a dirty shop or a dusty work area. The low horsepower rating makes it best for general-purpose single-speed machines rather than high-torque compressor duty. It requires a 208-230/460V supply and an appropriate starter, so you'll need to confirm your electrical layout and motor controls before wiring it. The unit is listed as new open-box, so check the package and motor thoroughly when it arrives. Choose it when a sealed, low-output motor for a harsh environment is your top priority, especially if you already have three-phase service available.
GARVEE 5HP SPL Air Compressor Electric Motor 230V 3450RPM 5/8\" Keyed Shaft Single Phase
This GARVEE motor is built specifically for air compressors, with a 5/8\" keyed shaft and a 56 frame that simplify direct replacement. It delivers 5HP and runs on standard 230V, which keeps installation simple when your compressor is wired for single-phase service. The CW/CCW reversible rotation lets you match the motor's direction to your pump, so you can get the rotation right during a swap. The ODP enclosure is more open than a TENV design, which means better airflow but less protection against heavy dust and moisture; keep it in a relatively clean and dry compressor area. For a straightforward 230V air compressor replacement, this is the motor that gets you running.
Final Choice by Use Case
Choose the GARVEE 5HP SPL when your compressor motor has failed and you want a direct 230V replacement with a keyed shaft and 56 frame. Choose the Baldor-Reliance CNM3457 when your shop has the 208-230/460V supply it needs and you want a sealed, general-purpose motor for a harsh industrial environment. Let your power supply and the machine's duty cycle guide the decision.
