Choosing between two industrial motors isn't just about horsepower. The 2 HP General Electric motor and the 5HP SPL air compressor motor are built for different electrical services and different jobs. Pick the wrong one and you'll face a phase converter project or a motor that can't handle the environment. Both are new units, but they're designed for very different roles. Here's a head-to-head breakdown to help you match the right unit to your equipment. The right choice comes down to your power supply and the type of equipment you're running.
Quick verdict: For a heavy-duty general industrial motor, go with the 2 HP General Electric. For a lower-priced air compressor specialist, go with the 5HP SPL.
| Feature | 2 HP General Electric Motor | 5HP SPL Air Compressor Motor |
| Price | USD 176.80 | USD 141.88 |
| Phase | Three-phase | Single-phase |
| Voltage | 230/460V | 230V |
| Enclosure | TEFC (fully enclosed fan cooled) | ODP (open drip-proof) |
| Frame | 56C | 56 |
| Standout specs | Inverter rated, Class F insulation | Keyed 5/8" shaft, dual rotation |
Where each product stands out:
- The 2 HP General Electric leads when you need a sealed, heavy-duty motor for a pump, conveyor, or machine tool. Its enclosure keeps out dirt and moisture, and the C-face design with removable base simplifies mounting. The 1.15 service factor also gives you a little overload headroom.
- The 5HP SPL compressor motor wins for air compressor service. At $141.88, it costs $34.92 less than the General Electric, and its 3450RPM speed is a natural match for compressor pumps. The 17.6A full-load current rating helps when you're matching a starter.
2 HP General Electric Motor 3 Phase 56C Frame 1800 RPM TEFC 230 / 460 Volt New
If your shop already runs on three-phase power, this motor is the more protected choice. The fully enclosed fan-cooled housing keeps dust, metal chips, and moisture away from the windings. It also carries a 1.15 service factor, Class F insulation, and an inverter-rated label, making it a good candidate for a variable frequency drive later. The 56C frame with a removable base and C-face mount gives you setup flexibility. The main limitation is that it won't start on single-phase service, and at 2 HP it's less powerful than the 5HP compressor motor.
Single Phase 5HP SPL Air Compressor Electric Motor 5/8" Keyed Shaft 230V 3450RPM
This motor is purpose-built for air compressor service. It runs on ordinary single-phase current, which is exactly what most residential and light-commercial compressors use. The 3450RPM speed, 5/8-inch keyed shaft, and 1.88-inch shaft length line up with common compressor pump requirements. You also get CW/CCW dual rotation (factory set to CCW), so you can adapt it to the direction your pump needs. The trade-off is that the open drip-proof enclosure offers less protection from dust and debris than a TEFC motor, and it's specialized for compressor duty rather than general-purpose machinery. If you don't have three-phase power, this is the motor that fits your setup.
Final choice by use case:
- Choose the 2 HP General Electric for a machine tool, pump, or conveyor where a heavy-duty motor is a priority.
- Choose the 5HP SPL for an air compressor where a high-RPM motor with dual rotation is the way to go.
