Motor Frame Sizes Provide Enhanced Energy Efficiency
Siemens Drive Technologies is supplementing
its energy-efficient IEC lowvoltage
motors with two new frame sizes
for the aluminum line and has also increased
power ratings on its cast-iron
motors. Siemens now offers the threephase
asynchronous motors of the
1LE1 series in frame sizes 80 and 90
as well as 100 to 160. These new
motors with aluminum housings are
available as 2- and 4-pole versions.
Their rotatable terminal box can be set
to any angle between 0° and 360°,
allowing the motor to be connected
from any direction and facilitating
installation where space is limited. In
the case of the cast-iron 1LG6 series,
extension of the 315 frame increases
the power rating to 315 kW. These
motors are available as 2-, 4-, 6- and 8-
pole versions. All motors are available
in efficiency class IE2 and meet the
requirements of EC Commission
Regulation 640/2009. The new cast
iron motors are also offered in efficiency
classes IE3 and NEMA Premium.
