1.5HP General Purpose Motor — 1750 RPM
Brand: Cuilvu. This three-phase general purpose motor delivers 1.5 HP with a four-pole design and a 56C frame. It is TEFC and suitable for 60 Hz operation at 230/460V, with a current range around 4.8/2.4A depending on voltage. The motor features a 5/8″ shaft diameter and a modest shaft length of 1.88″, IP55 protection, and a robust TEFC enclosure to protect it in dusty or moist environments. Applications include fans, pumps, and light machinery where consistent 1750 RPM is required.
5HP Air Compressor Motor — 1750 RPM
Brand: FAHKNS. Features a 5 HP, four-pole, 184T frame, TEFC enclosure, and IP54 rating. Operates at 208-230V with current draw around 27–28.5A. CW/CCW rotation offers wiring flexibility for different drive configurations. The motor employs a rolled steel shell for durability and includes a fully enclosed fan for effective cooling in wet or dusty work environments, helping reduce energy costs and extend service life. This motor is suitable for air compressors and other demanding industrial equipment.
5HP Industrial 1750 RPM Motor — 208-230V
Brand: Cuilvu. This 5HP motor uses a 184T frame and a TEFC enclosure with IP54 protection. It offers CW/CCW rotation and a 1-1/8″ shaft diameter with a 2.75″ shaft length. The design emphasizes heat dissipation through its robust rolling steel shell, making it suitable for heavy-duty air compressor or pump systems. It is compatible with environments where long-running operation is necessary, and it supports dual-voltage operation in the 208-230V range.
2HP 1750RPM TEFC Motor — 230/460V
Brand: Cuilvu. A general-purpose three-phase motor delivering 2 HP at 1750 RPM with a 56C frame and TEFC enclosure. It runs on 230/460V and draws about 7.2/3.6A depending on voltage. The shaft is 5/8″ in diameter with a 1.88″ length, IP55 protection, and stable performance for a wide range of equipment, from pumps to fans and small conveyors. This option serves as a compact, reliable choice for medium-duty industrial tasks.
1HP Farm Duty Motor — 1750 RPM
Brand: Cuilvu. This farm-duty single-phase motor runs at 1750 RPM and is rated for 115V/230V operation with a 56 frame and TEFC enclosure. It features a 5/8″ shaft diameter and 1.88″ shaft length, IP55 protection, and CW/CCW rotation for flexible mounting. Designed for agricultural machinery and general farm equipment, it is built for durability in open environments while maintaining reliable performance in continuous operation scenarios.
Buying Guide — Key Purchase Considerations
- Frame size and mounting: Choose a frame (56C, 184T, etc.) that matches your existing mounts and pulleys/belts. Ensure the shaft diameter and length fit your connections.
- Enclosure type: TEFC (Totally Enclosed Fan Cooled) is common for open or dusty environments; open drip-proof (ODP) may be cheaper but less protected.
- Voltage and wiring: Verify available power supply (115V, 230V, 208-230V, or 230/460V). Confirm single-phase vs. three-phase compatibility for your application.
- Rotation direction: CW/CCW capability can simplify installation and belt/pulley alignment; ensure the rotation matches your driven equipment.
- Cooling and environment: Look for features like a large fan and robust housing if the motor will run continuously or in hot or dusty settings.
- Efficiency and service life: Consider IP ratings and material quality (rolled steel shell, etc.) to ensure durability in harsh conditions.
- Maintenance and support: Availability of spare parts (bearings, seals) and warranty terms can affect long-term costs.
- Use case fit: Match horsepower and RPM with the load requirements of pumps, compressors, or conveyors to avoid oversizing or undersizing.
Across these options, 1750 RPM motors provide a reliable balance of torque and speed for a variety of industrial tasks, including air compressors, pumps, and general machinery. When choosing, prioritize enclosure protection, voltage compatibility, and physical fit with existing equipment to ensure smooth integration and dependable operation.
