Draft Booster Motor 1/12 hp

The Tjernlund 950-3022 is a shaded-pole draft booster motor rated at 1/12 hp for 115V AC single-phase supply. It delivers a nameplate speed of 600 RPM with a full-load draw of 1.0 A and fits a 3.3 frame. The motor shaft rotates CW/CCW for flexible installation. It serves as an OEM replacement for compatible draft-inducer assemblies.

Upgrade from worn or failed inducer motors

This unit replaces an existing draft booster that has lost torque, runs noisy, or trips on overload. The jump is worth it when the original motor no longer maintains the required draft pressure for the heating appliance. It restores proper venting without modifying the mounting footprint or electrical connection.

Sustained operation at rated load

Under continuous duty the shaded-pole design runs at the nameplate 600 RPM while drawing 1.0 A at 115V. The 3.3 frame dissipates heat through the motor body during extended heating cycles. Performance remains stable as long as supply voltage stays within nominal range and the blower wheel remains unobstructed.

Questions about this item

What frame size and shaft rotation does the 950-3022 motor use for mounting?

The motor uses a 3.3 frame and offers CW/CCW shaft rotation for flexible mounting.

How is the 1/12 hp shaded-pole motor wired during installation, and what voltage must be confirmed?

Wire the single-phase motor to a 115V AC supply; the step often missed is verifying the 1.0 A full-load amp rating matches the circuit.

When should the 3.41 lb draft booster motor be inspected or replaced in service?

Inspect the 600 RPM motor annually for bearing noise and shaft play; replace if vibration increases or the 1/12 hp output drops.
