MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP: The Complete Buyer's Guide for Worldwide Industrial Applications
Table of Contentsexpand_more
A MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP is a three-phase AC induction motor designed for industrial duty, delivering 5 horsepower at 1800 RPM (4-pole, 60 Hz) with a 182/4TC frame and C-face mounting. It operates on 208–230 V or 460 V and is commonly used to drive pumps, fans, and compressors in worldwide industrial settings.
A three-phase industrial motor is an electromechanical device that converts electrical energy into rotational mechanical energy using a rotating magnetic field. The 182/4TC frame designation specifies mounting dimensions and a C-face flange, ensuring compatibility with pumps and gear reducers. Brands like AMT PUMPS and HYPRO rely on motors with these specifications for their pedestal pump lines, where reliable torque and speed control are critical.
What Does 208-230/460V, 1800RPM, 182/4TC, 5HP Mean?
Each part of the motor designation tells you something essential. 208-230/460V indicates dual-voltage capability: the motor can be wired for 208–230 V or 460 V three-phase power, common in North America and export markets. 1800 RPM is the synchronous speed at 60 Hz for a 4-pole motor; at 50 Hz, the speed drops to approximately 1500 RPM. 182/4TC defines the NEMA frame size (182) and a C-face mounting flange (4TC), which allows direct coupling to pumps and reducers. 5HP is the rated output power.
How Does a Three-Phase Motor Work?
Three-phase power creates a rotating magnetic field in the stator, which induces current in the rotor and produces torque. The rotor turns slightly slower than the synchronous speed (slip), typically 1750 RPM at full load for an 1800 RPM motor. This design offers high efficiency, low vibration, and long service life compared to single-phase alternatives.

| Enclosure | ODP or TEFC (verify) |
| Efficiency | Premium (IE3) or Standard (IE2) |
Types and Applications
Motors with these specifications are available in several enclosure types: Open Drip Proof (ODP) for clean, indoor environments; Totally Enclosed Fan Cooled (TEFC) for dusty or damp conditions; and Washdown Duty for food processing. Common applications include centrifugal pumps, positive displacement pumps, cooling tower fans, and air compressors. In Worldwide markets, voltage and frequency variations mean you must confirm whether the motor will run at 50 Hz or 60 Hz, as speed and power output change accordingly.
Selection Criteria: How to Choose the Right Motor
- Voltage and Phase: Confirm your available power supply. 208–230 V is common in North America; 460 V is used for higher-power industrial circuits. For 50 Hz regions, expect lower speed and adjust pulley or impeller sizing.
- Frame and Mounting: The 182/4TC frame with C-face flange must match your pump or driven equipment. Check shaft diameter, keyway, and bolt circle.
- Enclosure: Choose ODP for dry, clean areas; TEFC for dusty, humid, or outdoor installations; washdown for sanitary environments.
- Duty Cycle and Service Factor: Continuous duty (S1) is standard for pumps. A service factor of 1.15 allows short-term overload.
- Efficiency and Certifications: Premium efficiency (IE3) motors reduce energy costs. For export, verify CE, CSA, or IEC compliance as needed.
- Environmental Conditions: Consider ambient temperature, altitude, and hazardous location ratings (e.g., explosion-proof for flammable atmospheres).
Product Selection Ladder: Pedestal Pumps and Motor Matching
While 3G Electric stocks motors and pumps across many categories, the following pedestal pumps illustrate how motor sizing works in practice. These pumps require specific motor HP and speed to achieve their rated performance.
| Product | Motor HP Required | Max Head | Shaft Outlet Diameter | Typical Application |
|---|---|---|---|---|
| AMT PUMPS Pedestal Pump 7 1/2 HP | 7 1/2 HP | 92 ft | 1 1/8 in | Industrial water transfer, dewatering, circulation |
| HYPRO Pedestal Pump 16 HP | 16 HP | 393 ft | 5/8 in | High-pressure transfer, spraying, agricultural irrigation |
When selecting a motor for these pumps, match the required HP and speed. The AMT PUMPS unit needs a 7 1/2 HP motor, while the HYPRO unit requires 16 HP. Both typically use 1800 RPM motors with appropriate frame sizes. Step up to a larger motor only if you need higher flow or pressure, and always verify the pump's maximum speed rating.
Worldwide Sourcing and Voltage Considerations
For international buyers, 3G Electric provides export documentation and can source motors with dual voltage and frequency ratings. In 50 Hz regions, a 4-pole motor runs at approximately 1500 RPM, which reduces pump flow and head. You may need to adjust pulley ratios or select a 2-pole motor (3000 RPM at 50 Hz) to achieve desired performance. All quotations are in USD, and we support incoterms-neutral supply to suit your logistics preferences.
According to AMT PUMPS Pedestal Pump Engineering Manual, 2022: "Motor selection must match the pump's required horsepower and speed. Operating a pump above its rated speed can cause premature wear and void warranty."
Frequently Asked Questions
Q: What is the difference between 182/4TC and other frames?
A: The 182/4TC frame has a 4.5-inch bolt circle and a C-face flange for direct mounting. It is not interchangeable with other frame sizes without an adapter.
Q: Can I use this motor on 50 Hz power?
A: Yes, but the speed drops to ~1500 RPM and horsepower decreases proportionally. Verify that your driven equipment can tolerate the reduced speed.
Q: Where can I buy a MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP in Worldwide?
A: 3G Electric supplies these motors globally with export documentation and technical support. Contact us for a quote.
