Below you will find definitions of terms, environmental conditions,
operating details and technical data for the planetary gear units.
All data, with the exception of the voltage constant, are based on
40 °C ambient temperature and 100 K overtemperature of the wind-
ing. The data can have a tolerance of +/- 10 %.
When attaching a gear unit, the performance may be reduced by up
to 20 %. The flange of a motor serves to dissipate heat. If a gear
unit is attached, heat is generated due to operation. The power der-
ating therefore has thermal reasons.
This chapter provides information on various technical terms and
their meaning.
Equivalent force on the output F
The equivalent force on the output describes the force that is rele-
vant for dimensioning the gear unit.
Equivalent application torque T
The equivalent application torque describes the torque that is rele-
vant for the dimensioning of the gear unit.
Dimensioning factor f
a
The dimensioning factor describes the influence of the daily operat-
ing time and the operating factor on the application torque.
Operating mode factor K
The operating mode factor describes the influence of duty cycle,
number of cycles and dynamics on the application torque.
Mass moment of inertia; based on the drive J
The mass moment of inertia is a measure for the tendency of a body
to maintain its motion state (whether at rest or in motion).
Running noise Q
[dB/A]
g
The gear ratio and speed affect the running noise.
In general, the following rule applies:
• Higher speed = higher running noise
• Higher gear ratio = lower running noise
