VEVOR 10 HP Electric Motor, 1770RPM
The VEVOR 10 HP Electric Motor combines high torque and robust construction for demanding air compression tasks. It operates at 1770 RPM and offers a large 40 N.m rated torque, which supports steady performance under load. Designed for three-phase AC power, it accepts 230V or 460V configurations at 60 Hz. The 215T frame provides a sturdy housing with a 1.375-inch shaft diameter and a 3.88-inch shaft length. A keyway of 0.31 inch ensures secure coupling to drive components. The motor supports dual rotation directions (CW/CCW), enabling flexible wiring and easier installation in various compressor setups.
Key considerations: ensure your control system and starter are compatible with three-phase motors at 230V or 460V. Check belt or coupling alignment to prevent vibration, and confirm frame mounting matches your compressor’s base. The durable frame and reversible operation contribute to longevity in workshop environments where air compressors run for extended periods.
VEVOR 7.5HP Air Compressor Motor, 230V
This 7.5 HP VEVOR motor offers a 3450 RPM rating in a 184T frame, optimized for higher-speed compression tasks. It is a single-phase unit with a full-load current around 31.6A, supporting 230V 60Hz operation. The shaft is 1-1/8-inch in diameter with a 2.75-inch length, and a 0.25-inch keyway supports secure drive coupling. The motor is reversible (CCW/CCW by factory setting) to simplify wiring and accommodate particular compressor configurations. While smaller than a true 10 HP option, this model delivers strong performance for mid-sized systems or as a matched partner to lighter-duty pumps.
Notes for buyers: verify your starter and control panel are sized for single-phase operation and that the 184T frame physically fits your mounting. Pay attention to the shaft size and keyway to ensure a proper fit with your compressor pulley or coupling, and confirm temperature rating aligns with your environment.
7.5 HP Motor Single Phase 184T
The 7.5 HP Cuilvu motor is a single-phase unit operating at 208-230V and 60Hz, delivering 3450 RPM with a 184T frame. It features a 1-1/8-inch shaft diameter and a 2-3/4-inch shaft length, plus a 0.188-inch keyway. The relocation from standard CCW to CW/CCW provides flexible wiring and simplified installation, especially on older or custom compressors. The enclosure is ODP, designed for open drip-proof cooling suitable for drier workshop environments.
Considerations include ensuring adequate ventilation to prevent overheating during continuous runs and validating that the power supply and contactor ratings match startup and running currents. This motor suits compact or retrofitted air compressors where a balance of speed and drive efficiency is needed.
VEVOR 3 HP Electric Motor for Compressors
The VEVOR 3 HP option is a compact, air-cooled motor designed for compressors and accessories requiring reliable performance at 230V. It features a 1.125-inch shaft diameter and a 2.75-inch shaft length within an 184T frame, with CW/CCW rotation and TEFC cooling. Designed for 1750 RPM operation, the motor provides 12 N.m torque, making it suitable for smaller pump loads, light-duty air systems, or as a starter motor in multi-mpeed configurations. The TEFC enclosure helps protect internal components in shop environments with dust or humidity, extending motor life.
Installation considerations include harmonizing its power draw with your starter and ensuring the shaft and keyway align with your compressor’s drive components. This model offers a good balance of size, efficiency, and control for smaller compressors or retrofit projects.
Air Compressor Motor 5HP TEFC 184T
The GCCSJ 5 HP motor is a robust choice for 208-230V mains, delivering 1750 RPM with a 184T frame. It is a single-phase TEFC unit featuring a rolled steel shell that supports S1 continuous operation. The 1-1/8-inch shaft diameter and 2.75-inch shaft length with a 0.188-inch keyway help ensure solid coupling to pumps. The motor includes a rolling fan for enhanced cooling, improving efficiency in dusty or humid shop environments. Its IP54 rating provides basic protection against dust and water splashes in typical workshop usage.
Buyers should verify the ambient conditions in their workspace and ensure the motor has appropriate ventilation. The open drip-proof aspect is more suitable for cleaner environments, while the TEFC design suits harsher or more humid locations. This model is well-matched to mid-sized compressors or as part of retrofit projects that need reliable, single-phase power.
VEVOR 5 HP Electric Motor, 1725RPM
The 5 HP VEVOR motor operates at 1725 RPM, with a 184T frame and a 1.125-inch shaft diameter. It offers CW/CCW rotation and 230V operation with TEFC cooling. The motor’s torque is listed as 20.7 N.m, which supports efficient operation in mid-range air compressors. The design emphasizes dual-direction wiring flexibility and a sturdy rolled steel shell to endure long-running cycles in workshop environments. This option suits users upgrading older equipment or building a new system around modest horsepower requirements while maintaining energy efficiency.
Buying Guide: Key Purchase Considerations
- Power and voltage: Verify the motor’s voltage (208-230V or 230V/460V) and whether your system runs on single-phase or three-phase power. Align motor ratings with your starter and electrical panel capacity to avoid overloads.
- Frame and shaft compatibility: Check the frame size (184T, 184T vs 215T) and shaft diameter/length, plus keyway width. Ensure your drive components, such as pulleys or couplings, fit securely and align properly to prevent premature wear.
- Rotation direction: Dual rotation (CW/CCW) can simplify wiring and accommodate diverse compressor configurations. Confirm factory settings if separate wiring changes are required.
- Cooling and enclosure: TEFC (Totally Enclosed Fan Cooled) offers better protection in dusty or humid environments, while ODP (Open Drip-Proof) suits cleaner spaces but may require more ventilation.
- Duty cycle and cooling: For continuous runs, prioritize motors designed for S1 duty with adequate cooling and heat dissipation. Larger frames generally support longer life under load.
- Ambient conditions: Assess environment for dust, humidity, or temperature. Enclosures and protective coatings affect longevity and maintenance needs in real-world shop settings.
- Maintenance and compatibility: Review availability of spare parts (bearings, seals, fans) and compatibility with existing compressor pumps, starters, and controllers to reduce downtime.
- Energy efficiency: Consider motors with high efficiency ratings and TEFC designs to minimize energy use during long operating sessions, especially in commercial or industrial contexts.
In summary, the five highlighted motors provide a spectrum of horsepower, frame sizes, and cooling options suitable for American air compressor setups. When selecting a motor, balance the mechanical fit with electrical availability, installation ease, and expected duty cycles to ensure reliable performance and extended service life.
