About the technical solution Compabloc
3000 geared motors with parallel gears
from Nidec Leroy-Somer are used to
adapt the speed of the electric motor to
that of the driven machine. The full range
comprises 10 different sizes. Among
the technical characteristics of this
family of geared motors, the following
in particular stand out: a rated output
torque of between 10 N.m and 14,500
N.m, a power output ranging from 0.06 to
110 kW, reduction ratios of between 1.16
and 252, and high efficiency of between
95 and 98%. It should also be noted that
these geared motors are reversible. This
equipment is also appreciated for its
quiet running.

In this way, Nidec Leroy-Somer can adapt
and customise its product ranges by
incorporating the requirements of the
customer specifications or processes
(control, self-diagnostic, communication,
automation, monitoring, etc.), the
requirements of the working environment
(humidity, corrosion, high temperature,
explosive atmospheres, etc.), the
machine function constraints (handling,
pumping, compression, ventilation, etc.),
and the industrial standards and norms
(chemicals, automotive, food, paper, naval
industries, etc.). Nidec Leroy-Somer has
developed new technologies for machine
