Electric-monorail geared motors
SIMOGEAR electric-monorail geared motors form part of our
SIMOGEAR product range.
SIMOGEAR electric-monorail geared motors have been
developed in cooperation with the conveyor technology and
automation industries (particularly the automotive sector).
The result of this development process is a finely scaled
program of geared motors with high permissible wheel loads.
State-of-the-art production technology and improved testing
methods ensure the highest degree of quality and reliability.
SIMOGEAR electric-monorail geared motors have been
designed using high-efficiency bevel gearboxes. The gear-
boxes for light-load applications are two-stage bevel gearboxes.
The drives for heavy-load applications are three-stage bevel
gearboxes.
BH.29 and BH.39 geared motors are suitable for use as an
electric-monorail drive in accordance with VDI guideline 3643.
Further information about design in accordance with
VDI guideline 3643 can be found in chapter "Configuring guide"
on page 2/4.

Benefits
High energy efficiency
for a fast return on investment
When developing SIMOGEAR geared motors, significant
emphasis was placed on achieving the highest possible energy
efficiency.
Using the plug-on pinion principle in the first SIMOGEAR
gearbox stage, higher transmission ratios are achieved when
compared to gearboxes with slip-on pinion.
Two-stage SIMOGEAR bevel geared motors B have a mechani-
cal efficiency of
96 %. With a range of transmission ratios from
i
= 8.5 to 60.21, they have been specifically designed to address
the requirements in conveyor technology.
Together with the Siemens 1LE1 motors for efficiency classes IE2
(High Efficiency) and IE3 (Premium Efficiency), SIMOGEAR
geared motors allow a high amount of energy to be saved and
reduce the stress on our environment.
Harmoniously coordinated modular system to provide
the optimum solution for your particular drive task
The fine size graduations of SIMOGEAR gearboxes provide you
with the optimum drive for every application regarding gearbox
type, rated output torque and transmission ratio.
When developing SIMOGEAR geared motors, significant
emphasis was placed on achieving well-balanced gearbox
properties.
With SIMOGEAR geared motors you can depend on harmonized
and coordinated properties regarding:
7
Maximum output torque
7
Permissible radial force
7
Output shaft diameter
7
Bearing service life
7
Housing stiffness
7
Gearing reliability (fatigue endurable)
7
Shaft strength (fatigue endurable)
7
Smooth running
The MODULOG modular principle
for outstanding flexibility
The motors used for the SIMOGEAR geared motors have a
modular design using our well-proven MODULOG modular
principle.
At the heart of the system is a basic motor dimensioned for inter-
national line supply conditions with power ratings extending
from 0.09 to 7.5 kW (2/4/6/8-pole).
At the non-drive end (NDE), you have an individually configu-
rable MODULOG modular system, e.g. for brakes, backstop,
rotary pulse encoder, separately driven fan and canopy.
