Motor Nameplate Information

The nameplate provides information that will assist a person in selecting the proper motor for the job, in making installation, and in energizing the motor with proper voltage.





• Universal Electric Motor: indicates that this is a standard replacement motor
• Thermally Protected: motor is equipped with devices designed to disconnect the current flow if insulating materials become too hot.
•SER 12P 14666J: manufacturer’s serial number
• MOD HE3E207N: manufacturer’s model number
• STK. NO. 619: manufacturer’s stock number
• VOLTS 208-230: motor can operate on either 208 or 230 volts
• HZ 60: frequency for which the motor is designed to operate
• AMPS 1.2: motor draws 1.2 amperes when operating at full load capacity
• RPM-1025: indicates motor turns 1025 revolutions per minute when pulling its rated load.
• PH1: motor runs on single-phase power
• CAP5MFD370VAC: motor is equipped with a continuous-operation run capacitor, rated at 5 microfarads and 370 volts AC
• INS CL B: motor has class B insulation, providing protection up to 130oC (266oF)
• AMB 60oC: motor is rated to work at an ambient of 60oC (140oF)
• HP-1/5: motor is designed to pull a 1/5 Hp load when operated at the rated voltage and cycle
• CONT: continuous duty
•Motor will pull rated load under rated conditions continuously and not overheat
•May have INT: intermittent duty; rated for 5, 15, 30, or 60 minute operating times
•AO: air-over ventilation is used to cool this motor
• ROT REV: indicates direction of rotation of the shaft
• BRG SLV: motor has sleeve bearings
• FRAME A48: designation that gives motor dimensions based on NEMA standards
Two-digit frame numbers ÷ 16 = distance in inches from centerline of shaft to foot of base
•TYPE FH: indicates motor is a fractional-horsepower motor
• SF 1.35: indicates motor will tolerate a 35% overload for extended periods
• SFA 3.5: number of amps the motor will draw when operating at the SF load of 1.35 times the rated Hp
• HSG OPEN: indicates type of motor enclosure
• CONNECTIONS: wiring diagrams for installation or changing direction of rotation.
