MOTOR ELECTRICAL DATA
The smallest motor available which equals or exceeds the Input power (kW) from the
chiller rating program is selected from Table 9 on page 60 to Table 12 on page 62.
The full load amperes (FLA) listed in the tables is maximum values and corresponds to
the maximum motor kW listed. When the input power (kW) is less than maximum motor
kW, the FLA should be reduced per the following equation:
FLA =
Motor kW x Maximum Motor FLA
Maximum Motor kW
The benefit from the FLA correction is the possible use of smaller power wiring and/or
starter size. The locked rotor amperes (LRA) are read directly from Table 9 to Table 12 for
specific Motor Code and voltage.
This is because the LRA is dependent only on motor size and voltage and is independent
of input power (kW). Inrush amperes (IRA) depend on LRA and the type of starter applied.
The inrush can be calculated using a percentage of LRA shown in Table 9 to Table 12.
