Century A.O. Smith Electric Motor 1/4-1/6 1625 MTRS8033

The Century A.O. Smith 9724 is a multi-horsepower motor rated 1/4 to 1/6 horsepower at 1625 RPM for fan, blower, and general air moving applications.

The 1625 RPM rating identifies a four-pole motor at the higher end of its speed range, faster than the 1075 RPM class used for direct-drive HVAC blowers and condenser fans. Higher shaft speed suits belt-driven applications, where a pulley ratio reduces the driven speed, and direct-drive applications using small propellers or wheels that require the speed to develop their rated airflow.

Speed class is a fitment specification in the same way horsepower is. A 1625 RPM motor is not a substitute for an 1075 RPM motor of the same rating, because the fan or blower attached to it was selected for a specific shaft speed and its airflow scales directly with that speed.

Read the nameplate speed of the motor being replaced rather than assuming a standard value.

Confirm horsepower range, RPM, voltage, rotation, frame diameter, shaft diameter and length, mounting arrangement, and run capacitor requirement before ordering, and verify the driven component is correct for the speed.
