3 Engineering Data Motor Selection Greenheck centrifugal fans can be supplied with any motor that is commercially available, and appropriate for the fan size and performance required. The tables show motor frame sizes corresponding to those motors readily available. See the maximum motor frame size charts below if motor is for arrangement 9 or 10 fans. Notes: 1. Fractional horsepower motor frame sizes shown may change due to variations in voltage, special features and manufacturer. 2. Motors shown are ball bearing, continuous duty. Two speed motors are two winding, 1/3 reduction in RPM. 3. Single-phase motors are capacitor start. HP Maximum Motor Frame Sizes Arrangement 9 and 10 fans have specific motor size limitations based on enclosure type (examples: Open, Totally Enclosed Fan Cooled) and voltage. The charts below should be used to verify the motor selected will physically fit on the fan.
