The National Electrical Manufacturer’s Association (NEMA) specifies that every motor nameplate must show these specific items: Manufacturer’s Name; Rated volts and full load amps; Rated frequency & number of phases; Rated full load speed; Rated temperature rise or the insulation system class; Time rating; Rated horsepower; Locked rotor indicating code letter; Service Factor; Efficiency; Frame Size; and Design Code. Additional information will normally appear on most nameplates.
This Technical Bulletin will go over the required nameplate items and many of the optional items that are shown on our Tatung nameplate. The required items will be covered first in the order previously mentioned.
Self explanatory; however, we like to see the name “TATUNG” on our nameplates!
Rated Volts And Full Load Amps
Tatung Motors will operate at a variety of line voltages, the most common being 230 and 460. These motors will operate according to NEMA limits at rated voltage.
Line voltage will fluctuate due to a variety of factors. Therefore, every motor must be designed to handle these voltage variations. Tatung motors can withstand voltage variation of plus or minus 10%, so a 230 Volt motor could operate between approximately 207 to 253 volts. At these extremes, no motor will run at its peak performance, however it will withstand these conditions.
The frequency the motor is designed for represented by Hertz (cycles per second). 60 Hertz power is used throughout the United States, Canada, and other parts of the world while 50 Hertz is the standard in the rest of the world. Tatung motors can tolerate a frequency deviation of plus or minus 5%. Most Tatung motors are 3 phase motors because of cost effectiveness.
