The US Motors 1697 is a high-performance 3/4 HP multi-speed blower motor designed for demanding HVAC applications requiring precision airflow control. Operating at 208-230V with a 1625 RPM nominal speed, this Permanent Split Capacitor (PSC) motor features a three-speed tap configuration, allowing technicians to fine-tune system static pressure. Built on a 48YZ NEMA frame, it utilizes a versatile ring or stud mount design and a 1/2" diameter shaft, making it a reliable direct drive blower motor replacement for various residential and light commercial air handlers. The open air over (OAO) enclosure promotes efficient thermal dissipation, while the self-aligning ball bearings ensure localized durability in high-cycle environments. With reversible rotation capabilities and a 4.4-4.2 Amp draw, this OEM replacement motor provides the torque necessary for consistent CFM delivery across modern coil configurations. Key Performance Benefits Multi-Speed Versatility: Triple-speed taps provide flexibility for balancing airflow across different ductwork static pressures. Contractor-Grade Durability: Engineered with self-aligning ball bearings to minimize friction and extend operational life in horizontal or vertical orientations. Universal Mounting: Features both extended through-bolt studs and resilient ring mounting for seamless integration into 48-frame brackets. Field Reversibility: Simple lead reversal allows for easy adjustment to CW or CCW rotation during installation. High-Efficiency PSC Design: Optimized electrical footprint reduces amp draw while maintaining consistent torque under load. Common Technical Questions Is the US Motors 1697 a suitable replacement for 3/4 HP furnace motors? Yes, provided the 48YZ frame dimensions and 1/2" shaft match your existing assembly. This motor is commonly used in high-static air handling units requiring 1625 RPM. How do I change the rotation on this motor? Rotation is electrically reversible; simply swap the rotation leads according to the connection diagram on the motor "nameplate" to match the blower wheel's required direction. What capacitor is required for the US Motors 1697? Detailed capacitor requirements are typically specified on the motor housing; ensure you use a correctly rated run capacitor to maintain proper phase angle and efficiency.
