Ruud 51-106546-01 Selectech Gen 3 Blower Motor 3/4 Hp

Product Description

The RUUD 51-106546-01 is a SelecTech Gen 3 variable-speed ECM blower motor designed as a direct-drive replacement for residential and light-commercial HVAC systems. Rated at 3/4 horsepower and compatible with 208 or 230-volt, 60 Hz single-phase power, this motor uses a shell-band mounting configuration and a 48Y frame. The 1/2-inch shaft diameter accommodates standard blower wheel hubs, and the ball bearing construction supports reliable long-term operation in forced-air applications. Licensed HVAC technicians handling furnace or air handler blower motor replacements will find this unit dimensionally and electrically matched to original equipment specifications.

This motor is suited for residential furnace blower assemblies and air handler fan decks where a SelecTech Gen 3 variable-speed motor is specified. The direct-drive design eliminates belt and pulley components, reducing maintenance points. It is appropriate for use in forced-air heating and cooling systems that require a 48Y frame, shell-band mounted blower motor. Installations involving Rheem and Ruud equipment are the primary application for this OEM replacement part.
