The Product Idea
´Combine the Advantages of the Two Products:
Planetary gear unit
Geared motor
high torque
transmission capability
many gear ratios
high torsional rigidity
fine gear ratio steps
very high permissible
radial forces
right-angle or coaxial
drive
compact unit
The planetary gear unit transmits the high torque while
the geared motor offers variability of gear ratios
and adjustment to the motor power.

Bearing Life
The Service Life of the Planetary Gear Anti-Friction Bearings is Very
High When Operated at Rated Torque:
L10h > 26,000 h
Combinable SEW Input Transmissions Were Selected to
Provide a Minimum Bearing Life of
L10h > 7,000 h.
The Service Life Values Given Above Apply for a Maximum Input Motor Speed of 1800 RPM.

Internal Safety Factors
The SEW Helical and Helical-Bevel Gear Units When Used as Input Transmissions for
the Planetary Gear Units Are Very Generously Sized. This is Evident in the Relatively
High Bearing Service Life, as well as, an Input Transmission fB Service Factor of 1.6.

Project Planning
Forces and Torques
Short-Time High Peak Torques are Possible up to 3.0 Moutpmax
No Reaction Forces Acting on Output Shaft Bearings, Therefore,
High External Load Capabilities
Oil Wells, Lubricant Capacity and Oil Level
Planetary Gear Units and Helical-Bevel or Helical Gear Units Always
Have Separate Oil Wells.
The Lubricant Capacity and the Oil Level of Both the Planetary Gear Units
and the SEW Input Transmissions are Documented in the "Planetary Geared
Motors" Catalog.
Please Note:
The SEW Input Transmissions are Factory-Filled with Oil as
Standard. The Planetary Gear Units are Supplied Without
Lubricant!

Sales Arguments
Increase in Customer Benefit
Customer gets completely assembled drive where all components are matched to each other
Planetary geared motor is more favorably priced than a combination of stand alone
planetary gear unit, adapter, coupling and motor
Planetary geared motor is shorter, as there are no intermediate elements such
as motor adapters and couplings
Wide variety of designs guarantee optimum drive selection for customer installation
Short delivery times of 3 to 4 weeks. If required shorter delivery times, it can be agreed
The customer can choose a standardized drive from the catalog.
This means the customer has the required technical data and dimension sheets
immediately available for project planning purposes
Extensive accessory options are available due to direct access to the SEW modular system
Worldwide sales and service network
Worldwide 24-hour service
All drives and components available from one supplier worldwide.
