2 HP Farm Duty Single Phase Motor, 3450RPM
The 2 HP Farm Duty Motor from Cuilvu is designed for robust, continuous operation in demanding environments. Its rolled steel shell supports a S1 continuous duty rating, making it suitable for pumps, conveyors, and agricultural equipment. Key specs include 115V/230V operation, 3450 RPM, and a TEFC enclosure with IP55 protection. The motor supports both CW and CCW rotation and uses a 56 frame with a 5/8″ shaft, ensuring compatibility with common pulleys and couplings in farm-duty setups.
2HP General Purpose 56C Three-Phase Motor
This general-purpose motor offers a versatile option for three-phase applications. With a 56C frame and TEFC enclosure, it delivers 3450 RPM at 60 Hz, compatible with 230V/460V supplies. It features shaft diameter of 5/8″ and a reversible rotation option, making it adaptable for a wide range of machines such as saws, pumps, and small machinery in workshops. The motor is designed for reliability in stationary industrial or agricultural settings.
2 HP 56C Single Phase, 115/230V, 3450RPM
Hex Autoparts offers a compact 2 HP motor with a 56C frame and TEFC enclosure. It supports 115/230V operation with full-load amps around 18.0A/9.0A, and a reversible 3450 RPM output. The 56C size makes it a common choice for bench machines, small fans, and pumps. The motor’s efficiency sits around typical levels for 2 HP class units, with standard 5/8″ shaft compatibility for common pulleys and couplings.
2 HP Farm Duty Motor, 56 Frame, 115/230V
This farm-duty single-phase motor emphasizes rugged construction and long life. With a 56 frame and 5/8″ shaft, it runs at 3450 RPM and supports both 115V and 230V operations. The design highlights include a fully enclosed system with heat dissipation features and a support for CW/CCW rotation. It is suited for farm equipment, water pumps, and other load-bearing applications where stable performance is required.
2 HP SPL Air Compressor Motor, 56 Frame
This 2 HP SPL motor is designed for air compressors, delivering 3450 RPM at 60 Hz with a 56 frame and 5/8″ shaft. It uses a 115V/230V configuration and features an Open Drip Proof (ODP) enclosure suitable for clean, dry environments. The motor is designed with a large heat sink and a robust rotating assembly to cope with continuous compressor operation, while maintaining efficient energy use and reliable cooling in typical shop conditions.
2HP General Purpose 56C, 1750RPM, 230/460V
Offering a lower-speed option, this 2 HP motor operates at 1750 RPM with a 56C frame and TEFC enclosure. It supports 230V/460V supplies and provides a reversible rotation feature. The motor is suitable for fans, pumps, and other applications requiring steadier, slower torque. With a 5/8″ shaft and typical efficiency for a 2 HP class unit, it is a good fit for belt-driven systems where reduced speed is advantageous.
Buying Guide
Key purchase considerations for 2 HP electric motors include:
- Motor type and enclosure: TEFC (Totally Enclosed Fan C cooled) protects against dust and moisture, while ODP (Open Drip Proof) is best in clean, dry environments. Farm-duty and general-purpose roles may favor TEFC for longevity in harsh conditions.
- Voltage and phase: 115V or 230V operation, and single-phase vs three-phase, determine wiring, starting methods, and energy efficiency. Ensure compatibility with your power supply and equipment CSA/UL compliance as needed.
- Frame size and shaft: A 56C or 56 frame with a 5/8″ shaft is common for 2 HP motors, offering wide compatibility with pulleys, belts, and couplings. Shaft length and mounting footprint affect mounting options.
- Rotation and wiring: Reversible rotation provides flexibility for different machines. Confirm whether CW/CCW rotation is supported and how to wire it for your setup.
- Duty rating and cooling: S1 continuous duty is suitable for non-stop operation, while SPL and open-frame designs may require adequate ventilation to prevent overheating.
- Efficiency and operating costs: Look for motors with reasonable efficiency ratings and consider full-load amps to estimate electrical demand and potential energy savings in continuous operation.
- Environment and protection: For dusty or damp environments, TEFC is generally preferred. ODP motors are good for cleaner shop settings but may require extra ventilation in dusty spaces.
- Maintenance and replacement availability: Availability of spare parts, seals, bearings, and compatible replacements can influence long-term maintenance costs.
With these factors in mind, the five highlighted models provide a cross-section of common 2 HP options suitable for workshops, small farming setups, and home equipment. When selecting, prioritize compatibility with your machinery, the power source you have on hand, and the environmental conditions where the motor will operate.
