The motor is designed for robust, continuous operation in industrial and workshop environments, delivering reliable performance across multiple applications.
2HP Electric Motor 1750RPM – Cuilvu
This 2HP motor runs at 1750 RPM with a 4-pole configuration, ideal for applications requiring higher torque at lower speeds. It’s a general purpose, three-phase motor with a 56C frame and TEFC protection. Both 230V and 460V inputs are supported, and the unit maintains IP55 protection for dusty or damp environments. Shaft dimensions match standard 56C motors to ensure compatibility with existing couplings and pulleys.
MA0520E 2 HP AC Motor – Hallmark
Hallmark’s MA0520E 2 HP motor is designed for inverter duty with a 56C frame and TEFC enclosure. It supports 60 Hz operation at 208-230V and 460V, and includes a protective Class F insulation rating. The packed steel shell ensures durability in demanding environments, making it suitable for conveyors, pumps, and processing equipment that use variable frequency drives or require consistent performance under varying loads.
VEVOR 2HP 3450 RPM – 3-Phase
VEVOR’s 2HP motor delivers 3450 RPM with AC 230V/460V support and a 56C frame. It emphasizes a robust 5/8″ keyed shaft and a 1.88″ shaft length, with a SF of 1.15 and CW/CCW rotation for easy wiring. The design targets agricultural machinery and general equipment, offering reversible operation for adaptable setups and simplified motor replacement in existing systems.
FAHKNS 2HP 4-Pole – 60Hz
The FAHKNS motor is a 2 HP, 4-pole machine designed for stability and efficiency at 60 Hz, compatible with 230V/460V power supplies. It features a 56C frame and TEFC enclosure, with a 5/8″ shaft diameter for common couplings. Built for continuous operation, it’s well-suited for agricultural equipment, pumps, and light industrial applications seeking reliable torque at moderate speeds.
Buying Guide: Key Purchase Considerations
- Voltage and Frequency: Most listed models support 230V/460V and 60 Hz. Confirm compatibility with your power supply and control hardware (VFDs or soft starters).
- Frame and Mounting: All options use a 56C frame. Check mounting patterns and shaft alignment with pulleys, couplings, and feet for your system.
- Enclosure: TEFC (Totally Enclosed Fan C cooled) protects against dust and moisture, suitable for harsh environments. Inverter-duty ratings (Class F insulation) are important for VFD use.
- Shaft and Keyway: A 5/8″ shaft with a standard 1.88″ length supports many belts and couplings. Ensure keyway dimensions match your drive components.
- Rotation: Reversible CW/CCW can simplify wiring and expansion in dual-drive setups, but verify wiring diagrams and motor direction requirements.
- One vs. Four-Pole Options: 2 HP motors at 3450 RPM (two-pole) deliver higher speed; 1750 RPM (four-pole) provides higher torque at lower speeds—choose based on load and RPM needs.
- Inverter Compatibility: If using variable frequency drives, select inverter-duty motors with appropriate insulation (Class F) and cooling to prevent overheating.
- Durability: Rolled steel shells and robust frames extend service life in industrial settings, while TEFC protects internals in dusty or damp environments.
- Maintenance: Consider availability of spare parts, bearings, and end-shield options for long-term maintenance and repair.
These options cover a spectrum of common 2 HP three-phase applications, from lightweight automation to farm equipment and small manufacturing lines. When selecting, align motor characteristics with the mechanical load, desired speed, and the electrical setup to ensure efficient and reliable operation over time.
