These heavy-duty motors are suitable for use with fans, blowers, whole-house fans, air circulators, air coolers and more.Nameplates differ according to manufacturer, and a variety of factors, such as dirt and damage, can hide crucial information needed to size a Variable Frequency Drive (VFD), make a repair, find a replacement, correct the power factor, purchase parts, or do almost anything with the motor.But even a clean nameplate can be confusing with all of the abbreviations and codes used in such a small space.The following guide is designed to help you understand the crucial information contained on your motors nameplate.
Step 1: Gather Nameplate Information Listed below is the information you will need to select your motor. If you are replacing an existing motor, the following information can be located on the nameplate of the motor. See the sample nameplate on this page: Phase (PH): Either single (1) or three (3). Service Factor (SF): This should be an equal or greater number. ![]() Shaded Pole - Small direct-drive fans and blowers b. Split-Phase - Belt-drive and direct-drive fans and blowers, small tools, centrifugal pumps, and appliances d. Antique Ge Fan S Trial Ventilators ECapacitor-Start - Pumps, compressors, tools, conveyors, farm equipment, and industrial ventilators e. Phase - Applications where 3-Phase power is available Enclosure (Encl.): See below. ODPOpen - Clean, dry, non hazardous environments b. Enclosed TEFCTENV - Dirty, moist, non hazardous environments c. Hazardous - Designed for use in hazardous environments as defined by National Electric Code (NEC) classifications. NEC Class and Group are designated on UL Hazardous Location nameplate mounted on the motor. Antique Ge Fan S Upgrade To ContinuousDuty Cycle: If the current motor is an intermittent duty, it is possible to upgrade to continuous. Air-over must be installed in the driven fan blades airstream. Bearing Type: Sleeve or ball bearings Thermal Protection Step 2: Determine Your Motor Type General-Purpose Motors are intended for mechanical loads, air-moving, and for hard to start applications such as conveyors, belt-driven equipment, machine tools, and reciprocating pumps. These motors utilize ball bearings to handle heavier loads and heavier construction for industrial applications. Definite-Purpose Motors are used in specific applications and the motors features are all driven by the specific application. Such motors include washdown, hazardous location, pump duty, etc. HVAC Motors are designed primarily for air moving and other light to medium duty applications such as fans, centrifugal pumps, small tools, and office equipment. DC Motors are used in numerous industrial applications because the speed to torque relationship is so flexible. Antique Ge Fan S Full Torque CanSpeeds can be varied, and full torque can be reached within the operational speed range. DC Motors are used on constant-torque loads such as conveyor belts, elevators, cranes, and more. Step 3: Select the Motor Sustainable Supply has a great selection of electric motors, including HVAC motors, definite purpose motors, dc motors, and more Order today and take advantage of fast shipping on the many varieties of industrial and commercial motors.
