1 hp OEM Replacement Motor for HVAC Systems
The Schaefer 1 hp OEM replacement motor is a single-phase AC motor designed for HVAC and refrigeration equipment. It uses a capacitor-start design and delivers two operating speeds with a nameplate RPM of 1,725 and 1,140. This new motor runs on 115V AC power and draws 12.4 A at full load.
Verify Voltage, Mounting
Confirm that your equipment requires a 115V AC single-phase supply and can accommodate a cradle-base mounting arrangement. Check that the existing capacitor-start circuit matches the motor design and that the circuit can provide the rated 12.4 A full-load current. Ensure the two-speed operation aligns with the original unit's control scheme.
Cradle Base Mounting and Class B Insulation
The motor features a cradle-base mounting type that secures directly to the equipment frame without a standard NEMA frame size. Class B insulation provides thermal protection during continuous operation in HVAC environments. The transparent colour allows visual inspection of the windings and internal components during routine maintenance.

Questions about this item
Does the 1 hp motor ship with the capacitor and mounting hardware included, or must they be purchased separately?
The listing describes only the motor itself; the capacitor-start design and cradle base are built in, so no separate capacitor or mounting kit is mentioned.
Should I choose the 1,725 RPM or the 1,140 RPM speed setting for a standard 115 V AC condenser fan?
The motor offers two fixed speeds — 1,725 RPM and 1,140 RPM — select the one that matches the original fan’s nameplate RPM for proper airflow.
What does the 12.4 A full-load amp rating mean for the circuit breaker and wiring on a 115 V AC supply?
At full load the motor draws 12.4 A on 115 V AC, so the branch circuit and breaker must be sized for at least that continuous current.
