Baldor Motor 05f198w052g1 Air Over Motor 1 Hp 1750 Rpm

Product Description

The BALDOR MOTOR 05f198w052g1 is a 1 HP air over, Super-E premium-efficient industrial electric motor built for three-phase applications running at 230 or 460 volts, 60 Hz. Rated at 1750 RPM with a 143T frame, it draws 2.8 amps at 230 volts and 1.4 amps at 460 volts. The air over design means the motor relies on an external airstream for cooling, making it a common choice for fan and blower duty where the moving air passes directly over the motor housing. It ships in manufacturer packaging and is made in the USA.

This motor is suited for commercial and industrial fan or blower installations where an external airstream provides continuous cooling. The 143T frame and single-ended 7/8-inch shaft make it a direct fit for many OEM fan assemblies and replacement applications. Licensed electricians and mechanical contractors typically handle installation in HVAC air-handling equipment, commercial ventilation systems, and industrial process fans requiring a compact, efficient three-phase drive.

Key Features

• Super-E premium-efficiency design reduces operating costs in continuous-duty applications
• Air over (AO) cooling configuration — no self-cooling required, suited for direct fan and blower duty
• Dual-voltage rated: 230 or 460 volts, 60 Hz, three-phase
• 143T NEMA frame for standardized mounting and shaft compatibility
• Single-end shaft measuring 7/8 inches in diameter by 2-3/8 inches in length
• Reverse rotation configuration as shipped
• Domestic manufacture — made in the USA

Compatibility

Designed as an OEM-style replacement or new-installation motor for three-phase air over fan and blower assemblies using a 143T NEMA frame and a 7/8-inch single-end shaft.

Installation Notes

Installation should be performed by a licensed electrician or qualified mechanical contractor in accordance with the NEC and applicable local codes. Disconnect and lock out all power before mounting or wiring the motor. Verify supply voltage matches the selected motor winding connection — 230 or 460 volts — before energizing. Confirm that sufficient airflow passes over the motor housing at all times during operation, as the air over design provides no self-cooling when airflow is absent.
