Baldor 5 HP Single Phase Electric Compressor Motor – 184T Frame, 208–230V

The Baldor 5 HP Single Phase Electric Compressor Motor (184T, 208–230V) is a dependable, compressor-duty motor designed for shops, garages, and light industrial environments that need consistent performance from their air systems. With a true 5 HP output, 184T frame, and 1-1/8" shaft, it is an excellent choice for both new builds and as a replacement for many 5 HP air compressor motors.

Technical Specifications

• Horsepower: 5 HP
• Voltage: 208–230V, single phase
• Full Load Amps: 22.2–21.2 A
• Speed: 1750 RPM (1800 RPM class)
• Frame: 184T
• Shaft Diameter: 1-1/8" keyed shaft
• Service Factor: 1.25 (1.00 @ 208V)
• Phase: Single phase
• Rotation: Reversible (field reversible)
• Application: Castair spec compressor motor

These specifications make this motor a strong fit for users looking for a 5 HP single phase compressor motor that runs smoothly on 208–230V service while providing the torque required for demanding compressor applications.

Designed Specifically for Compressor Duty

Air compressors place unique demands on a motor. They require high starting torque, stable RPM under load, and the ability to tolerate frequent starts and stops. This Baldor 5 HP motor is configured with those needs in mind.

Key compressor-duty advantages:

1. High starting torque
   Built to handle starting piston and rotary compressor pumps, even under system pressure, helping reduce nuisance trips and hard-start issues.
2. Continuous duty rating
   Suitable for applications where the compressor cycles regularly or runs for extended periods, as long as the motor is installed with proper ventilation and protection.
3. Generous service factor
   The 1.25 service factor at 230V offers extra thermal and mechanical margin during heavy use, which is valuable in shops that run compressors daily. At 208V, the motor operates at a 1.0 service factor, aligning with correctly sized overload protection.

Fitment and Replacement Guidance

Correct fitment is critical when choosing a replacement air compressor motor. This model is built on a familiar, widely used footprint.

1. Frame 184T

• Defines the mounting bolt pattern, shaft height, and base footprint.
• If your current motor nameplate shows 184T, this Baldor motor will typically mount to the existing base with little or no modification.

2. 1-1/8" keyed shaft

• Matches the shaft bore on many 5 HP compressor pulleys.
• In most cases, you can reuse your existing sheave, provided it is in good condition and properly aligned.

3. Speed and pulley sizing

• Rated at approximately 1750 RPM.
• If you are replacing a higher-speed (e.g., 3450 RPM) motor, you will usually need to adjust pulley sizes to maintain the correct pump RPM and CFM output. This is standard practice when setting up or reconfiguring a belt-driven compressor.

Ideal Uses and Applications

While this unit is often sold and specified as a 5 HP compressor motor single phase 184T, it is suitable for a range of belt-driven loads when the mechanical and electrical requirements match.

Common applications include:

• Reciprocating (piston) air compressors
• Smaller belt-driven rotary or scroll compressors (where compatible)
• Belt-driven water or process pumps
• Blowers and ventilation fans
• Light industrial and agricultural machinery requiring 5 HP, 1750 RPM, single-phase power

For best results, the motor should be placed in a location with adequate airflow and reasonable protection from dust and moisture.

Benefits for End Users

This Baldor motor is a practical choice for customers who want reliable performance without unnecessary complications.

1. Reliable operation
   Designed with industrial-quality components, this motor is well suited for daily use in busy shops, small manufacturing facilities, and serious home garages.
2. Consistent performance
   Provides stable speed and torque under normal compressor loading, which supports steady air delivery and helps the system maintain pressure without excessive cycling.
3. Straightforward replacement
   The common 184T frame and 1-1/8" shaft dimensions simplify the upgrade or replacement process. Reversible rotation allows you to match the existing belt layout and direction of rotation more easily.
4. Single-phase convenience
   Ideal for facilities without three-phase power. The motor runs on standard 208–230V single-phase service when installed and wired according to code and manufacturer recommendations.

Summary of Key Features

• 5 HP, single-phase, 208–230V compressor-duty electric motor
• 184T frame with 1-1/8" keyed shaft for easy integration on compatible compressor bases
• 1750 RPM speed, optimized for belt-driven air compressor pumps and similar loads
• 1.25 service factor at 230V for added margin during heavy or extended use
• Reversible rotation for flexible installation and belt routing
• Castair spec motor suitable as a high-quality replacement on many 5 HP compressor systems

For customers seeking a 5 HP single phase electric compressor motor that offers dependable starts, solid performance under load, and a familiar mounting footprint, the Baldor 184T 208–230V model is a strong, shop-ready solution.
