MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP: The Complete Buyer's Guide for Worldwide Industrial Buyers
Table of Contentsexpand_more
A MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP is a three-phase AC induction motor rated 5 HP at 1800 RPM, wound for 208–230/460 V dual-voltage operation and built on a NEMA 182/4TC frame with a C-face mounting. It is the standard drive package for centrifugal pumps, pedestal pumps, fans, and general industrial machinery where a compact, footless C-face motor is required.
At 3G Electric, we interpret your demand — voltage, frequency, frame, enclosure, and duty — then source the right motor or matched pump package from our global supply network. With over 35 years of experience across combustion, pumps, and controls, we supply far more than our listed catalog, including AMT PUMPS and HYPRO pedestal pump packages that pair directly with 5 HP-class motors.
What does "MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP" actually mean?
Each element of the designation is a specification, not marketing copy. Reading them correctly is the difference between a drop-in replacement and a returned shipment.
- 208-230/460V — dual-voltage, three-phase winding. Low-voltage connection runs 208–230 V; high-voltage connection runs 460 V. Rewiring at the terminal block selects the mode.
- 1800 RPM — nominal synchronous speed at 60 Hz for a 4-pole motor. At 50 Hz the same motor runs at approximately 1500 RPM, so pump curves must be re-checked for 50 Hz markets.
- 182/4TC — NEMA 182 frame with a 4TC C-face flange. The "TC" denotes a C-face with threaded mounting holes, allowing direct coupling to a pump or gearbox without a foot mount.
- 5HP — rated output. This is the mechanical power delivered at the shaft, not the electrical input.
A 5 HP, 1800 RPM motor is the workhorse of medium-duty fluid handling. It is the size class that matches pedestal pumps in the 7½–16 HP input range when driven through appropriate impellers and couplings, such as the AMT PUMPS and HYPRO pedestal units we stock.
Spec table: MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP
| Parameter | Value | Notes |
|---|---|---|
| Rated output | 5 HP (3.7 kW) | Shaft power at rated load |
| Voltage | 208–230/460 VAC, 3-phase | Dual-voltage, reconnectable |
| Frequency | 60 Hz nominal (50 Hz variant available) | Speed changes with frequency |
| Speed | 1800 RPM at 60 Hz (≈1500 RPM at 50 Hz) | 4-pole induction motor |
| Frame | NEMA 182/4TC | C-face, threaded mounting holes |
| Enclosure | ODP or TEFC (specify) | TEFC for washdown/dust |
| Service factor | Typically 1.15 | Confirm on datasheet |
| Mounting | C-face, footless | Direct pump/gearbox coupling |
Every value above must be confirmed against the specific manufacturer datasheet before ordering. Frame, enclosure, and service factor vary by OEM and by market variant.
How does a 182/4TC C-face motor mount to a pump?
The 4TC C-face flange bolts directly to a matching pump bracket, eliminating the need for a foot mount, baseplate, or alignment shim stack. The motor shaft couples to the pump shaft through a rigid or flexible coupling sized to the 182 frame shaft diameter.
This is why C-face motors dominate pedestal pump applications. The AMT PUMPS pedestal pump (sized for 7½ HP, up to 92 ft of head, 1⅛ in shaft outlet) and the HYPRO pedestal pump (sized for 16 HP, up to 393 ft of head, ⅝ in shaft outlet) both accept C-face motor mounting in their respective size classes. Matching the motor frame to the pump bracket is the single most common source of fitment error.
According to NEMA MG 1, Motors and Generators, 2021 revision: "A motor shall be so designed and constructed that when connected to a circuit of the proper voltage and frequency, it will operate successfully under the conditions specified." Buyers should verify the nameplate voltage and frequency against the actual supply before installation.
Which motor variant suits your application?
Three variables drive the selection: enclosure, efficiency class, and market voltage/frequency.
- ODP (Open Drip Proof) — indoor, clean, dry environments. Lowest cost, adequate for many pump rooms.
- TEFC (Totally Enclosed Fan Cooled) — washdown, dust, outdoor, or humid environments. The default for food, agriculture, and dewatering duty.
- Premium efficiency (IE3/NEMA Premium) — required in many markets for continuous-duty industrial motors. Reduces operating cost over the motor's life.
- 50 Hz export variant — for markets on 50 Hz supply, the same 4-pole motor runs at approximately 1500 RPM. Pump impellers and system curves must be re-evaluated; a 60 Hz selection is not a drop-in for a 50 Hz site.
For worldwide buyers, the practical rule is: specify the supply voltage and frequency of the installation site first, then select the motor winding and pump curve to match. A 208–230/460 V, 60 Hz motor is correct for North American supply; a 400 V, 50 Hz variant is correct for much of Europe, Asia, Africa, and South America.
Selection criteria: how to choose the right 5 HP motor
- Confirm supply voltage and frequency. 208–230/460 V at 60 Hz, or the 50 Hz equivalent for export markets. Never assume the nameplate matches the site.
- Match the frame to the driven equipment. 182/4TC C-face must match the pump or gearbox bracket. Verify shaft diameter and keyway.
- Select the enclosure for the environment. ODP for clean indoor; TEFC for washdown, dust, or outdoor.
- Check duty cycle and service factor. Continuous duty with a 1.15 service factor is typical; intermittent or high-inertia loads may require a larger frame.
- Verify efficiency class. IE3/NEMA Premium where mandated or where energy cost justifies it.
- Confirm the pump curve at the actual speed. A 4-pole motor at 50 Hz delivers roughly 83% of its 60 Hz speed — flow and head change accordingly.
Product selection ladder: matched pump packages
The table below compares the pedestal pump packages we stock that pair with 5 HP-class and larger motors. Use it to step from light-duty water transfer up to high-pressure spraying.
| Model | Motor sizing | Max head | Shaft outlet | Typical duty |
|---|---|---|---|---|
| AMT PUMPS Pedestal Pump, 7½ HP, 92 ft Head | 7½ HP | 92 ft | 1⅛ in | Industrial water transfer, dewatering, circulation in sumps, pits, tanks; clean or slightly contaminated fluids |
| HYPRO Pedestal Pump, 16 HP, 393 ft Head | 16 HP | 393 ft | ⅝ in | High-pressure transfer and spraying in agricultural, irrigation, and industrial fluid handling |
Step up the ladder when head or pressure demand exceeds the smaller unit's curve — the HYPRO unit delivers more than four times the head of the AMT unit and is the correct choice for spraying and high-pressure transfer. Step down when the duty is simple transfer or dewatering and the higher head is unnecessary.

Frequently asked questions
What is a MOTOR, 208-230/460V 1800RPM, 182/4TC, 5HP used for?
It drives centrifugal and pedestal pumps, fans, and general industrial machinery requiring a compact C-face motor. The 182/4TC frame bolts directly to a matching pump bracket, making it the standard choice for medium-duty fluid handling in sumps, transfer systems, and process loops.
Can I use a 60 Hz motor on a 50 Hz supply?
Not without re-evaluating the system. A 4-pole motor runs at approximately 1500 RPM at 50 Hz instead of 1800 RPM at 60 Hz. Pump flow and head drop accordingly, and voltage must match the site. For 50 Hz markets, specify a 50 Hz-rated motor and re-check the pump curve.
What is the difference between 182/4TC and a foot-mounted 182 frame?
The 4TC suffix denotes a C-face flange with threaded mounting holes and no feet. It mounts directly to the driven equipment, eliminating baseplate alignment. A foot-mounted 182 frame bolts to a baseplate instead. They are not interchangeable without an adapter.
How do I get a quote for worldwide delivery?
Contact 3G Electric with your voltage, frequency, frame, enclosure, and quantity. We provide quotes in USD, handle export documentation, and supply on incoterms-neutral terms. Lead time depends on stock status and destination; confirm at enquiry.
ODP or TEFC — which enclosure should I choose?
Choose ODP for clean, dry, indoor locations. Choose TEFC for washdown, dust, humidity, or outdoor installation. TEFC costs more but protects the winding in demanding environments and is the safer default for agricultural and dewatering duty.
