VEVOR 3HP Air Compressor Electric Motor
VEVOR’s 3HP motor is designed for 230V single-phase power with a 56-frame size. It delivers up to 3 horsepower at 3450 RPM and draws a full-load current around 15.5A, making it a solid choice for compact air compressors and workshop equipment. The motor features a 5/8-inch keyed shaft and a shaft length of 1.88 inches, suitable for direct coupling. Open drip-proof construction favors clean, dry environments while offering a longer service life when properly mounted. Rotation is selectable (factory setting CCW). The robust steel housing supports durability in daily use.
3HP Electric Motor, GCCSJ, 208-230V
This GCCSJ model is a 3HP, 3450 RPM single-phase motor compatible with 208-230V systems and a 56C frame. It emphasizes heat management with a fully enclosed fan and substantial heat sinks for sustained operation. The motor supports CW/CCW rotation and operates with a TEFC (totally enclosed fan-cooled) design for improved protection in varied environments. It’s compact yet powerful, designed to maximize efficiency and longevity in air compressors and similar machinery.
Thomletha 3HP SPL Single Phase Motor
The Thomletha 3HP SPL motor targets single-phase applications with 3450 RPM and a 56-frame footprint. It supports 115-230V operation and is constructed from durable steel for longevity in household and commercial setups. Its CCW rotation makes it a flexible option for compressors and pumps where rotation direction can impact performance. Suitable for a variety of general-purpose tasks and small industrial equipment, this motor balances power with reliability.
GCCSJ Air Compressor Motor, 3HP 115/230V
This GCCSJ model covers both 115V and 230V operation with a 56-frame size and 60Hz frequency. It features an open drip-proof (ODP) enclosure suitable for dry environments, and a CCW rotation option. The motor’s design emphasizes high efficiency and a compact form factor, including a robust heat sink configuration to support longer runtimes in demanding compressor duties.
3HP Electric Motor 3450RPM Farm Duty Motor
This GCCSJ farm-duty motor is engineered for 230V operation with a 145T frame and 7/8-inch shaft diameter, rated at 3HP and 3450 RPM. It features a TEFC enclosure and a 60Hz specification, designed for agricultural or heavy-duty workshop uses. The design prioritizes reliability under continuous or long-running conditions and supports CW/CCW rotations for versatile mounting and drive configurations.
Buying Guide
- Voltage and frequency: Most 3HP motors for 220–240V systems run at 60Hz. Confirm your supply voltage and frequency to avoid heat or speed mismatches.
- Enclosure type: TEFC (Totally Enclosed Fan Cooled) is common for protective weather and dust resistance, while ODP (Open Drip Proof) suits clean, dry interiors. Choose based on environment and maintenance access.
- Frame size and shaft specs: The 56, 56C, or larger frames define mounting compatibility. Shaft diameter and length (e.g., 5/8″ x 1.88″) affect coupling and pulley choices.
- Rotation direction: CW vs CCW orientation matters for pumps, fans, and conveyors. Many motors offer dual-direction, but check the factory setting and whether rotation can be swapped without rewiring.
- Single-phase vs three-phase: For residential or small shops, single-phase motors (often 115V or 208-230V) are common; three-phase variants provide higher torque and efficiency in larger systems.
- Cooling and efficiency: Motors with robust heat sinks and external fans can run cooler, extending service life during high-load cycles typical of air compressors and farm-duty equipment.
- Maintenance and life expectancy: Look for die-cast or steel housings and quality bearings. A longer service life reduces downtime and replacement costs.
- Compatibility: Ensure the motor’s shaft size, mounting configuration, and pulley alignment match your existing drive system and accessories.
- Warranty and support: Check warranty terms and vendor support for technical guidance during installation or troubleshooting.
Overall, when selecting a 3HP 220V motor, consider environment, load profile, and drive compatibility. The options above cover a range of applications from compact air compressors to farm-duty equipment, offering configurations for both single-phase and dual-voltage installations. For best results, align motor specifications with your machine’s requirements and consult the manufacturer’s installation guide.
