Design
The motors described in this catalog are surface-cooled, low-
voltage motors designed for the highest demands on availability
and reliability. The motors are extremely rugged and reliable and
可以作为标准版本而没有爆炸保护，
as well as in the Ex nA, Ex d(e), Ex p and Ex e types of protection.
对于极端要求，电动机可用双人
protection against gas and dust.
The highly efficient motors cover the power range of 0.25 to
1400 kW in 2- to 16-pole versions (higher power ratings are
可以根据要求），并符合IEC 60034-30-1
they achieve efficiency class IE2 in the power range 0.75 to
2-，4和6极版本的375 kW，可用
for 50 Hz and 60 Hz.
The LOHER CHEMSTAR and SIMOTICS XP motor series are self-
ventilated, surface-cooled finned motors for line and converter
手术。
The LOHER VARIO series, which is also surface-cooled, is
characterized by its special internal air circulation / hollow
fin technology for an extremely high power density with a very
高效率。
