Many useful equations and tables.For instance, it can be difficult distinguishing between hp and ph, or 5 and 2. The motor nameplate information that will generally be required on a test report are: phase(s), voltage, amperage, service factor, speed, ... (within the motor), locked rotor amperage, torque characteristics, internal protection, insulation classification, and the wiring diagram. ... Example 21 A threephase, 25 horsepower, dual voltage motor has the following ratings: 230/460 volts, 68/34 amps, 1.10 service factor.
