C.Power Supply Identification

The nameplates of DC motors intended for operation from rectified power supplies will be stamped with a power supply identification as described below.

1.When the test power supply used as the basis of rating is one of the five described below, a single

letter "A”, “C”, “D”, “E” or “K” will be used to identify the test power supply

.

a.Power Supply Identification Letter “A”

This designates a DC generator, battery or any power supply with enough series inductance to result in no more than 6% peak-to-peak armature current ripple.

b.Power Supply Identification Letter “C”

This designates a three-phase, 60 hertz input, full-wave power supply having six total (con- trolled) pulses per cycle. The power supply has no free-wheeling and no series inductance. The input line-to-line AC voltage to the rectifier shall be 230 volts for 240 volt DC motor rat- ings, and 460 volts for 500 or 550 volt DC motor ratings.

c.Power Supply Identification Letter “D”

This designates a three-phase, 60 hertz input, semi-bridge power supply having three- controlled pulses per cycle. The supply has free wheeling with no series inductance added ex- ternally to the motor armature circuit. The input line-to-line AC voltage to the rectifier shall be 230 volts for 240 volt DC motor ratings and 460 volts for 500 or 550 volt DC motor ratings.

d.Power Supply Identification Letter “E”

This designates a three-phase, single-way (half-wave) power supply having three total pulses per cycle and three-controlled pulses per cycle. The power supply has no free wheeling and no series inductance added externally to the motor armature circuit inductance. The input line-to- line AC voltage to the rectifier shall be 460 volts for 240 volt DC motor ratings.

e.Power Supply Identification Letter “K”

This designates a single-phase, full-wave power supply having two total (controlled) pulses per cycle with free wheeling 60 hertz input and no series inductance added externally to the motor armature circuit. The input AC voltage to the rectifier shall be 230 volts for 180 volt DC rat- ings.
