Constructed from durable steel, it is designed for clean, dry environments and emphasizes longevity with open drip-proof housing to assist heat dissipation during continuous use.
VEVOR 5HP SPL Air Compressor Motor
This SPL (Super Premium Lift) variant by VEVOR delivers 5HP at 3450 RPM with 230V operation. It has a 56 frame and a 5/8″ keyed shaft with 1.88″ shaft length. The motor is open drip-proof and built to withstand typical workshop environments. Suitable for two-pole machines, it is designed to provide reliable performance with CCW/CW rotation, depending on wiring configuration, and maintains solid heat dissipation through a robust steel body.
Bonvoisin 5HP Air Compressor Motor
The Bonvoisin 5HP motor is a single-phase, 230V unit rated at 25A full load and designed with a 56HZ frame. It uses a 7/8″ keyed shaft with a 2.25″ shaft length and supports CCW/CW rotation. Engineered for durable service, its frame and construction help resist heat buildup in dry environments. This model emphasizes straightforward wiring and quick setup for air compressors that require reliable, continuous operation.
Mixizap 5HP Air Compressor Motor
The Mixizap 5HP motor is an 184T frame, single-phase unit operating at 208-230V with 60 Hz. It delivers 3450 RPM and a full-load current around 24.9A. It features a 7/8″ shaft with a 2 1/4″ keyway, plus a solid cooling approach to handle extended running times. The TEFC? style enclosure emphasizes protection against dust while maintaining efficient performance. A good fit for 5HP air compressors requiring robust power delivery.
Dollate 5 HP SPL Air Compressor Motor
The 5 HP SPL motor from Dollate is designed for air compressors with 56 frame, 230V operation, and open drip-proof enclosure. It uses a 5/8″ shaft diameter and a 1.88″ shaft length with a 2-pole, CCW rotation standard. It supports CCW, with the option to switch rotation by wiring. The motor emphasizes compact design and heat dissipation to sustain performance across workloads in dry workshop environments. Installation is straightforward for common compressor setups.
Buying decisions for 5 HP air compressor motors often hinge on frame compatibility, shaft size, rotation direction, and heat management. The five models above offer a balance of common 56-frame configurations and rated power that align with many standard air compressors. When selecting, consider the shaft diameter, length, and whether CCW or CW rotation is required by your pulley or belt arrangement. Also verify enclosure type (ODP/TEFC) and whether the environment requires enhanced dust protection or moisture resistance.
Buying Guide
- Compatibility: Ensure the motor’s frame, shaft diameter, and shaft length align with your compressor. Mismatches can require adapters or belt realignment.
- Rotation: Confirm rotation direction (CW or CCW) matches your compressor’s pulley layout. Some motors offer dual rotation with simple wiring changes.
- Enclosure and Cooling: Open Drip-Proof (ODP) is common for dry workshops; TEFC provides enhanced protection in harsher environments. Consider cooling features for continuous duty.
- Electrical specs: Check voltage (230V), phase (single-phase for most home shops), and full-load amperage to ensure your circuit can supply the motor safely.
- Durability: Look for robust frame construction (56 Frame or 184T, etc.), high-quality steel, and heat dissipation features to extend service life.
- Maintenance: Consider motors with accessible wiring, simple mounting patterns, and clear manuals for installation and maintenance.
- Replacement readiness: Choose widely-supported brands with readily available replacement parts and known compatibility with common air compressors.
