In some applications more than 1 motor design would work; in others, if an exact replacement cannot be found, a similar motor with slight differences in mechanical and electrical characteristics will provide reliable operation. The following selection guide is designed to help you choose the correct motor for your application.  \nSTEP 1: GATHER MOTOR INFORMATION  \nYou will need the following information to properly select a motor. If you are replacing a motor, much of the information can be found on the existing motor nameplate. See the sample nameplate on this page:  \n1-Phase (PH): Either single (1) or three (3) . Match exactly.  \n2-Voltage (Volts): Match exactly.  \n3-Horsepower (HP): Very small motors are often rated in watts. Choose an equal or next higher HP. 4-Physical Size/Frame (FR): Match exactly. 5-Speed (RPM): Match within 5% .  \n6-Frequency (Hz): Match exactly.  \n7-Service Factor (SF): Choose a motor of equal or greater number.  \n8-Type: See table below.  \n9-Enclosure (Encl.): See table below.  \n10-Duty Cycle: If current motor is intermittent duty, you may upgrade to continuous. Air-over must be installed in the driven fan blade's airstream. 11-Bearing Type: Sleeve or Ball.  \n12-Thermal Protection  \nSTEP 2: DETERMINE THE RIGHT MOTOR TYPE General-Purpose Motors are designed for mechanical loads (also effective for air moving), and for hard-to-start applications such as conveyors, belt-driven equipment, machine tools and reciprocating pumps. These motors feature ball bearings to handle heavier radial and axial loads and heavier construction for industrial applications.  \nDefinite-Purpose Motors are designed for specific applications such as washdown, hazardous location, pump duty, etc. Motor features are driven by the specific application's environment.  \nHVAC Motors are designed mostly for air moving and other light-to medium-duty applications, such as fans and centrifugal pumps, small tools and office equipment.  \nSTEP 3: SELECT THE SPECIFIC MOTOR  \nMatch the information gathered in Step 1 on [Grainger.com](Grainger.com)® or call a local branch.  \nAC MOTOR TYPES  \nPhase Type  \nTypical RPM  \nStarting Torque as Percent of Full-Load Torque  \nComparative  \nEfficiency Typical Uses  \n\n| 1 | Shaded Pole | 1050, 1550,\u003Cbr>3000 | Very Low 50-100% | Low | Small direct-drive\u003Cbr>fans and blowers |\n| --- | --- | --- | --- | --- | --- |\n| 1 | PSC | 825, 1075,\u003Cbr>1625 | Low 75-150% | Moderate | Direct-drive fans\u003Cbr>and blowers |\n| 1 | Split-Phase | 1140, 1725,\u003Cbr>3450 | Low to Moderate\u003Cbr>130-170% | Moderate | Belt-drive and direct\u003Cbr>drive fans and blowers,\u003Cbr>small tools, centrifugal\u003Cbr>pumps, and appliances |\n| 1 | Capacitor-Start | 1140, 1725,\u003Cbr>3450 | Moderate to High\u003Cbr>200-400% | Moderate\u003Cbr>to High | Pumps, compressors, tools, conveyors, farm equipment, and industrial ventilators |\n| 3 | 3-Phase | 1140, 1725,\u003Cbr>3450 | Moderate to High\u003Cbr>200-300% | High | Applications where 3-Phase power is available |\n\nENCLOSURE TYPES  \nEnclosure Type How Can I Tell?
