VEVOR 2HP Air Compressor Electric Motor
The VEVOR 2HP motor provides 3450 RPM with dual voltage operation (115V/230V) and a 56-frame configuration. It features a 5/8″ keyed shaft with a 1.88″ shaft length and a 0.188″ keyway, suitable for air compressors and other small equipment. Open drip-proof design favors clean, dry environments and a sturdy steel body enhances service life. Full-load amps are 20A at 115V and 10A at 230V, making it a practical choice for compact, high-speed applications.
2 HP Electric Motor Farm Duty Single Phase
Designed for farm and workshop duty, this 2 HP motor operates on 115V or 230V and supports a 3450 RPM 56-frame TEFC (totally enclosed fan-cooled) construction. It uses a rolled steel shell and a safe, durable S1 continuous operating system. The motor is rated for 60 Hz operation with an AC input of 18.2A at 115V or 9.1A at 230V, delivering reliable performance in demanding environments typical of agricultural and industrial settings.
2HP Electric Motor 3450 RPM General Purpose
This general-purpose 2HP motor features a 56C frame and TEFC enclosure, with IP55 protection and a 5/8″ shaft diameter. It supports 115V/230V input and delivers 3450 RPM for fast start-up and consistent speed in light-industrial tasks. The shaft length is 1.88″ with a standard 0.125″ keyway, and the housing is constructed from rolled steel to balance durability with a compact footprint.
Air Compressor Motor, 2 HP SPL
This 2 HP SPL motor operates at 3450 RPM with a 56-frame design and a 5/8″ shaft. The open drip-proof (ODP) enclosure is suited to clean, dry environments and includes a robust rolled steel shell for enhanced durability. The motor uses a 60 Hz power supply and offers a current draw of 15A at 115V or 7.5A at 230V, making it a strong pick for compact air compressor units and small machinery requiring reliable speed and torque.
2HP Electric Motor 3450 RPM Three Phase
This 2HP motor is a three-phase unit rated at 230V/460V with a 56C frame and TEFC enclosure. It delivers 3450 RPM and supports CW/CCW rotation, offering flexibility for machinery that requires variable direction operation. A rolled steel shell enhances durability, and the motor is designed for continuous operation under S1 conditions, delivering robust performance in industrial and manufacturing contexts.
Buying Guide
- Operating voltage and phase: Determine whether you need single-phase (simpler wiring, common in homes and small shops) or three-phase (higher efficiency and torque for larger equipment). Many 2HP motors are available at 115/230V; 230V/460V variants are common for three-phase machines.
- Enclosure style: TEFC (totally enclosed fan-cooled) protects internal components from dust and moisture, suitable for tougher environments; ODP (open drip-proof) may be adequate in clean, dry spaces but provides less protection.
- Frame and shaft specs: Match the frame size (56, 56C) and shaft diameter (commonly 5/8″) to your mounting hardware, pulleys, couplings, and belts. Shaft length (1.88″) and keyway size (0.188″ or 0.125″) affect mounting and transmission fit.
- Speed and rotation: Most 2HP motors operate at 3450 RPM (high speed) or 1750/3500 RPM variants. CW/CCW rotation compatibility is important for belt and pulley alignment and for equipment that depends on rotation direction.
- Open vs. enclosed design: OD P motors suit clean environments; TEFC options are preferable for dusty or humid spaces and provide longer service life with reduced maintenance.
- Durability and build: Look for rolled steel shells and robust mounting provisions. Check for continuous operation ratings (S1) if you expect constant duty or heavy loads.
- Maintenance considerations: Verify bearing types, shaft seals, and availability of spare parts like seals and brushes (where applicable). Consider motor efficiency and energy use over the device’s lifetime.
- Installation and safety: Ensure wiring, mounting, and protective devices comply with local codes. When possible, select motors with compatible protective enclosures and thermal protection.
Across these options, single-phase motors are typically best for residential or small workshop setups, while three-phase units excel in heavier-duty applications with higher torque requirements. In all cases, verify compatibility with your specific equipment, including pulley ratios and shaft alignment, to ensure optimal performance and longevity.
