It comes with a 23172604 reference, designed for reliable industrial performance. The model targets users needing a direct compatibility bridge to existing IR systems and emphasizes stable operation in general workshop environments.
GENERIC 23172604 7.5HP Air Compressor Motor
This 7.5HP motor is marketed as a compatible option for Ingersoll Rand units, featuring 3450 RPM at 230V single-phase operation. It uses a 213T frame and a 1-1/8″ shaft. The listing highlights OE-part-number compatibility and aims to deliver dependable performance for industrial air compressors that rely on familiar, trusted components.
FAHKNS 7.5HP ODP 3450RPM Motor
FAHKNS offers a 7.5HP ODP motor with a 184T frame, 1-1/8″ shaft, and 2.75″ shaft length. It operates at 3450RPM on 208-230V supply, with CW/CCW rotation and a high-efficiency design. The open drip-proof (ODP) construction suits clean and dry environments and emphasizes heat dissipation through substantial heat sinks for sustained performance.
Buying Guide
Key purchase considerations:
- Voltage and phase: Ensure the motor is a single-phase 230V unit compatible with your power source and wiring setup.
- Frame and shaft: Match the 184T or 213T frame and the 1-1/8″ shaft with your pump or pulley configurations. Check shaft length and keyway size for secure mounting.
- Rotation direction: Many motors support CW/CCW; confirm the needed rotation for your compressor drive system.
- Protection and environment: Open drip-proof vs. enclosure protection affects reliability in dusty or damp settings. Choose ODp for cleaner environments, or enclosed designs for harsh surroundings.
- AMPS and startup: Full-load amperage (approx. 29–34A) informs wire sizing and circuit protection. Plan for adequate startup current in your electrical setup.
- Frame compatibility and replacement: If replacing an Ingersoll Rand or other branded motor, verify OE part numbers and compatibility to avoid mismatches.
- Durability features: Look for bearings, heat sinking, and frame rigidity that support continuous operation in industrial or workshop contexts.
- Availability of CW/CCW: Reversibility can simplify wiring and retrofits if you are upgrading an existing unit.
Performance comparisons: All listed options deliver about 7.5HP and 3450RPM, suitable for typical 60Hz systems. The main differences lie in frame compatibility (184T vs 213T), shield type (ODP vs open frame), and rotation direction capabilities. For environments requiring robust heat management, models with larger cooling features and heat sinks may offer longer service life under heavy use. Always verify exact shaft dimensions and mounting patterns against your compressor’s specifications before purchasing.
