Marathon 10 HP General Purpose Motor
The Marathon motor is a 3-phase general purpose unit designed for 208-230/460 V operation with a 10 HP rating. It offers compliance with efficiency standards and adaptable frame options (182T-365T for steel frames, 404T-449T for cast iron). It supports inverter duty and variable torque profiles, suitable for pumps, fans, and conveyors in industrial settings. Choose this motor when high-power, reliable operation and compatibility with renewable or energy-efficient drive systems are priorities.
VEVOR 7.5HP Air Compressor Motor
VEVOR’s 7.5 HP motor is a high-output, single-phase unit rated for 230 V with a 3450 RPM speed and 184T frame. Its dual rotation direction (CCW/CCW) simplifies wiring and installation, while the open drip-proof design is suited for clean, dry compressor environments. This motor is appropriate for demanding air compressor applications that require robust starting torque and steady operation.
VEVOR 5HP Air Compressor Motor (230V, 17.6A)
This 5 HP, 230 V motor delivers solid full-load current capacity at 17.6 Amps with a 56-frame size and a 1.88″ shaft length. It features open drip-proof protection and a sturdy steel build for long life in dry, clean environments. Suitable for mid-range air compressors and general-purpose machinery requiring reliable 5 HP power.
VEVOR 5HP Air Compressor Motor (CCW) 230V
This 5 HP motor operates at 230 V with a single phase supply and 25 A full-load current. The 56HZ frame and 2.25″ shaft length provide longer shaft engagement, while its open drip-proof housing supports use in clean, dry environments. The motor is reversible (CCW/CW) for flexible wiring and installation.
VEVOR 3.7HP Air Compressor Motor
Offering 3.7 HP at 230 V, this motor suits lighter air compressor duties or smaller machinery. It runs at 3450 RPM with a 56 frame and 1.88″ shaft length, and features an open drip-proof design for reliable operation in clean environments. It provides a practical balance of power, size, and efficiency for compact systems.
Buying Guide
- Motor type: Choose between single-phase and three-phase based on your power supply and load. Three-phase motors are common in industrial settings and often more efficient for continuous duty.
- RPM and service factor: Higher RPMs enable faster operation but may require precise gearing. Service factor (SF) indicates tolerance for overload; a SF of 1.0 is standard, while higher SF values offer additional headroom.
- Frame size and shaft: Ensure the frame (e.g., 56, 184T, 215T) matches your mounting footprint. Shaft length and keyway size affect coupling and pulley compatibility.
- Rotation direction: Some motors offer CCW/CW or only one direction. Verify rotation needs and wiring methods before installation.
- Protection and environment: Open drip-proof (ODP) motors suit dry environments; consider enclosure motors for dusty or wet locations. Steel constructions improve durability under load.
- Efficiency and compliance: Look for NEMA or equivalent efficiency ratings and inverter-duty compatibility if variable-speed control is needed.
- Maintenance: Check lubrication, bearings, and accessibility for belt or pulley replacements to minimize downtime.
- Installation considerations: Verify voltage compatibility (230 V vs 208-230 V), amperage, and available circuit capacity to prevent tripping and overheating.
