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
1329R motors at 575V are rated 1850V insulation value.
Recommended MTE Reactor and LC Filter:
1 hp at 4kHz use MTE part number:
RL– 00803C
1 hp at 6/8kHz use MTE part number
RL– 00202C
2/3/5 hp use MTE part number
RL– 00803C
7.5 hp use MTE part number
RL– 01803C
10 hp use MTE part number
RL– 01803C

ATTENTION: The 1302 AC Drive does not provide
input power short circuit fusing. Specifications for the
recommended fuse size and type to provide Drive input
power protection against short circuits are provided in
Table 3.F. Branch circuit breakers or disconnect
switches cannot provide this level of protection for
Drive components.
Input line branch circuit protection fuses must be used to protect the
input power lines. See Figure 5.A. Table 3.F shows recommended
fuse values. These fuse ratings are applicable for one Drive per branch
circuit. No other load may be applied to that fused circuit. Note that
contactors and circuit breakers are not recommended for AC input line
branch protection.
