Type A Motor Characteristics: No phase paper or misplaced phase paper, lower quality insulation systems, corona inception voltages between 850 and 1000 volts.
Type B Motor Characteristics: Properly placed phase paper, medium quality insulation systems, corona inception voltages between 1000 and 1200 volts.
1329R Motors: These AC Variable Speed motors are “Power Matched” for use with Allen-Bradley Drives. Each motor is energy efficient and
designed to meet or exceed the requirements of the Federal Energy Act of 1992. All 1329R motors are optimized for variable speed
operation and include premium inverter grade insulation systems which meet or exceed NEMA MG1. Part 31.40.4.2.
NR = Not Recommended

Values shown are for 480V nominal input voltage and drive carrier frequency of 2 kHz. Consult factory regarding operation at carrier frequencies above 2 kHz.
Multiply values by 0.85 for high line conditions. For input voltages of 380, 400 or 415V AC, multiply the table values by 1.25, 1.20 or 1.15, respectively.

A 3% reactor reduces motor and cable stress but may cause a degradation of motor waveform quality. Reactors must have a turn–turn insulation rating of 2100
volts or higher.

Includes wire in conduit.
