Motors and Copmpressors
Chapters 14-24
Number of Slides: 389
No day passes without the discovery of new ways to use the most efficient and most important device ever invented, the electric motor. Without it, the wheels of industry would grind to a halt and millions of time and labor saving devices would be rendered useless.
AC electrical motors are designed and selected by finding the three currents that make up the circuits that supply the power to the motors. The first current found is the full-load amps (FLA) from Table 430.248 for single-phase and Table 430.250 for three-phase.The second current determined is the nameplate amps found on the motor. And the third current is the locked-rotor current (LRC), in amps, from Table 430.7(B) for motors with code letters and Tables 430.251(A) and (B) for motors with design letters.
AC electrical motors are designed and installed in a wide variety of sizes, types, and styles, ranging from tiny fractional horsepower units to very large machines of 20,000 HP and larger. These types of motors can be either of single-phase or three-phase construction based on the horsepower and voltage.
Part III covers motor theory, types of motors, and the regulations of the National Electrical Code® that pertain to the design and installation of these motors.
