Weg 00336es1e145tc-w22 Tefc Motor 3 Hp 143/5TC

Product Description

The WEG 00336es1e145tc-w22 is a totally enclosed fan-cooled (TEFC) three-phase electric motor rated at 3 HP with a 2-pole configuration and a 143/5TC frame. Built to high-efficiency standards, it delivers reliable rotational power in demanding industrial and commercial environments. The TEFC enclosure protects internal windings from dust, moisture, and debris, making it suitable for both indoor and outdoor installations. Licensed electricians and industrial maintenance technicians are the primary installers of this motor in pump, fan, compressor, and conveyor drive applications.

This motor is designed for use in light industrial and commercial mechanical systems where a 3 HP, 2-pole output is required. The 143/5TC frame designation follows NEMA standards, allowing straightforward mounting in applications that call for that frame size. Typical installations include small pumps, blowers, air compressors, and material handling equipment. Its high-efficiency design helps reduce energy consumption over continuous-duty operating cycles.

Key Features

• TEFC enclosure shields windings from dust, moisture, and particulates
• 3 HP output rating suitable for small pump, fan, and compressor drives
• 2-pole design for higher synchronous speed output
• NEMA 143/5TC frame for standardized mounting and coupling
• High-efficiency construction reduces operating energy draw

Compatibility

Designed as an OEM-style replacement or direct-drive upgrade for NEMA 143/5TC frame motor applications in industrial and commercial mechanical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power to the drive circuit before removing the existing motor or making any wiring connections. Verify that the supply voltage, phase configuration, and amperage capacity of the circuit match the motor nameplate ratings before energizing. Confirm proper coupling or belt alignment after mounting to prevent premature bearing wear.
