VEVOR 3/4HP Electric Motor — 1725 RPM
This motor runs at 1725 RPM with a 56-frame size and a 5/8″ keyed shaft. It supports both 115V and 230V single-phase power and includes reversible CW/CCW rotation. With a full-load current around 12A/6A depending on voltage, it suits agricultural machinery and general equipment where reliable, moderate horsepower is needed. Best for stationary machinery in workshops or farms where wiring can accommodate dual voltage and a reversible setup.
Best for: Agricultural equipment and general machinery that benefit from reversible rotation and a compact 56-frame motor. Choose this if you need quick wiring and a robust frame for durable operation. Caution: Verify shaft length (1.88″) and keyway size (0.188″) match your drive pulley or coupling.
VEVOR 1HP Electric Motor — 1725 RPM
This single-phase motor delivers 1 horsepower at 1725 RPM in a 56C frame. It operates on 115V or 230V and draws around 14.5A at full load on 115V or 7.5A on 230V. It also features a 5/8″ keyed shaft and a reversible CW/CCW rotation, enabling flexible installation across various machines. Best for heavier-duty compressors or conveyors that demand more torque than a 3/4HP unit. Caution: Ensure your power supply and wiring can handle the 14.5A current at 115V.
Best for: General-purpose, single-phase equipment requiring higher horsepower while keeping a compact 56C frame. Better for systems that need straightforward wiring with reversible rotation. Avoid this if your circuit cannot safely supply >14A at 115V.
VEVOR 1.5HP Electric Motor — 1725 RPM
Designed for robust duty, this 1.5HP motor runs at 1725 RPM and is configured for 115V/230V, 60Hz, with a SF (service factor) of 1.15. It uses a 56C frame, a 5/8″ keyed shaft, and a shaft length of 1.88″. The motor supports reversible CW/CCW rotation and is suitable for agricultural machinery and general equipment that benefit from higher torque. Best for demanding air compressors and machinery where higher horsepower is preferred. Caution: Higher horsepower means greater power draw; ensure electrical and mechanical mountings are appropriate for the load.
Best for: Applications requiring more torque and power without stepping up to industrial three-phase options. Choose this if your equipment can accommodate a 56C frame and dual-voltage operation. Avoid if your space or budget favors smaller, more energy-efficient units.
GF2026 Electric Fan Motor — 1/4 HP
This 1/4 HP motor runs at 1725 RPM with 115V and features a 48-frame design and ball bearings. It uses a reversible rotation and a cradle base with a shaft diameter of 1/2″ and a height of 3″. This model is suited for smaller ventilation fans, blowers, or replacement motors in residential or light commercial HVAC components. Best for compact, space-constrained installations where moderate airflow is sufficient. Caution: This is a lower horsepower option; consider load requirements to avoid under-powering larger systems.
Best for: Replacement in small fans or air ducts where space is limited and a light-duty motor is adequate. Choose this if you need a compact 48-frame unit with reversible rotation. Avoid if your project demands higher airflow or torque for heavy-duty tasks.
GF2034 Blower Motor — 1/3 HP
This 1/3 HP blower motor runs at 1725 RPM on 115V with a 48-frame design. It includes a capacitor (7.5μF/370V) and supports reversible rotation, making it a versatile choice for HVAC blowers or air handling components. Best for retrofit projects where a broader range of compatible part numbers is important, especially when replacing older Packard, Emerson, or Baldor units. Caution: It lists a broad compatibility set; verify the exact motor replacement matches your model’s bolt pattern and shaft size.
Best for: Replacement in legacy blower systems or universal motor configurations that require a compatible 48-frame motor with a reversible shaft. Choose this if you need a ready-to-install option with a capacitor included. Avoid if your system uses a non-48-frame footprint or a unique capacitor value is essential.
Buying Guide: 1725 RPM Motors — Key Considerations
- Frame size and mounting compatibility: A 56-frame or 48-frame motor fits different housings. Confirm the physical dimensions and bolt patterns match your equipment.
- Voltage and phase: Most options here are single-phase 115V/230V. Ensure your electrical supply supports the required voltage and current without overloading circuits.
- Shaft size and coupling: Keyed shafts (commonly 5/8″) and specified shaft lengths (1.88″) influence pulley or coupling compatibility. Check keyway width (0.188″) as well.
- Rotation direction: Reversible CW/CCW rotation provides flexibility in wiring. Plan motor orientation and wiring to avoid cross-wiring or power phase errors.
- horsepower and torque: Higher HP (e.g., 1.5HP) yields more torque but increases current draw. Match motor power to the load for efficiency and longevity.
- Service factor and build quality: A service factor around 1.15 indicates some allowance for peak loads. Use this when your application experiences brief torque spikes.
- Intended application: Compressors, fans, and general equipment have different torque and startup requirements. Ensure the motor’s speed and frame align with your device’s demands.
How to choose quickly
- Need reversibility and moderate horsepower? Consider the 3/4HP model first.
- Planning a heavy-duty compressor or conveyor? The 1HP or 1.5HP options provide extra torque.
- Working with space constraints? Check frame size and shaft dimensions to fit existing mounts.
- Low-power, small-space HVAC needs? The 1/4 HP GF2026 is a practical match.
Installation and safety tips
- Follow manufacturer wiring diagrams for 115V vs 230V configurations and observe safety grounds.
- Use appropriate mounting hardware and vibration isolation to reduce wear on bearings and belts.
- Inspect shaft seals and bearings during installation; replace worn components to prevent premature failure.
- Confirm rotation direction before connecting belts or pulleys to avoid mechanical damage.
