2HP Electric Motor 3450 RPM (Cuilvu)
This general-purpose three-phase motor delivers 2 HP with a 56C frame and TEFC enclosure, suitable for versatile industrial applications. It operates at 60 Hz with 230V or 460V options and provides CW/CCW rotation. The shaft diameter is 5/8″, and the motor is designed for rolling steel shell construction with IP65 protection. A compact choice for pumps, fans, and machinery that require reliable, continuous operation.
2HP Electric Motor 1750RPM (Cuilvu)
This 4-pole, 2 HP motor operates at 1750 RPM, ideal for equipment that requires higher torque at lower speeds. It features a 56C frame, TEFC enclosure, and dual voltage support (230/460V). With IP-55 protection and CW/CCW rotation, it is suitable for conveyors, blowers, and other general purpose machinery. The 5/8″ shaft diameter and 1.88″ shaft length provide robust coupling options.
Hallmark MA0520E 2HP AC Motor
Hallmark’s MA0520E offers a compact, robust 2 HP motor designed for inverter duty and general three-phase use. It provides 1725 RPM with a 56C frame and TEFC enclosure, meeting typical industry standards for continuous operation. This model emphasizes durability with a solid steel shell and a SF rating suitable for demanding loads. It is commonly paired with variable speed drives and mechanical drives in industrial settings.
VEVOR 2HP 3450 RPM Three-Phase Motor
VEVOR’s 2HP motor is built for high-speed operation at 3450 RPM, with dual voltage support (230V/460V) and a 56C frame. It features a 5/8″ keyed shaft, a 1.88″ shaft length, and a sturdy rolled steel shell. The motor supports reversible CW/CCW rotation, simplifying wiring and installation. The inverter-ready design makes it suitable for agricultural machinery and general equipment applications where quick setup and reliability are important.
FAHKNS 2HP Three Phase Motor
This 2HP, 4-pole motor operates at 60 Hz with 230/460V input and a 56C frame. It uses a TEFC enclosure and a 5/8″ shaft diameter, with a shaft length of 1.88″. The housing is rolled steel, designed for S1 continuous duty and long service life. It is well-suited for general purpose equipment that benefits from steady torque and durable construction in wet or dusty environments.
Buying Guide
- Voltage and frequency: Ensure the motor supports your available supply (230V/460V and 60 Hz are common for North American setups).
- Frame size and mounting: A 56C frame is a standard size; verify mounting compatibility and shaft alignment with your drive or coupling system.
- Enclosure type: TEFC (Totally Enclosed Fan Citted) protects against dust and moisture; consider IP ratings (e.g., IP55, IP65) for harsher environments.
- Rotation direction: CW/CCW capability is essential when upgrading or retrofitting existing equipment; reversible motors facilitate setup flexibility.
- Duty cycle and cooling: For continuous operation (S1), ensure adequate cooling and consider fans or inverter-driven cooling strategies for long runs.
- Efficiency and motor type: Inverter-compatible motors are recommended if speed control is needed; check the SF rating and insulation class for reliability under load.
- Maintenance and compatibility: Cross-check shaft diameter, keyways, and couplings; TEFC enclosures generally require less maintenance in dusty or humid settings.
- Application fit: Align motor horsepower with your load requirements; oversizing can increase cost and improve durability, while undersizing risks overheating.
