General information about the
data provided in this catalogue
Outputs, torques and speeds
The outputs, torques and speeds specified in the catalogue
are rounded values and apply to:
˘
Operating time/day = 8 h (100% OT)
˘
Duty class I for up to 10 switching operations/h
˘
Mounting positions and designs in this catalogue
˘
Standard lubricant
˘
f
mains
= 50 Hz constant
˘
T
amb
= 20°C for gearbox
40°C for motors (in accordance with EN 60034)
˘
Site altitude < = 1000 m amsl
˘
The selection tables provide the permissible mechanical
powers and torques. For notes on the
thermal power limit, see page 2-2.
˘
The rated power specified for motors and geared
motors applies to operating mode S1 (in accordance
with EN 60034).
Under different operating conditions, the values
obtained may vary from those listed here.
In the case of extreme operating conditions, please
consult your Lenze sales office.
Load capacity c of gearbox
Characteristic value for the load capacity of Lenze geared
motors.
˘
c
is the ratio of the permissible rated torque
of the gearbox to the rated torque delivered by the
drive component (e.g. the integrated Lenze motor).
˘
c
must always be greater than the
application factor k determined for the application.
Application factor k (corresponding to DIN 3990)
Takes account of the effect of any loads that are actually
present and that vary during the anticipated operating time
of gearboxes and geared motors.
k
depends on
˘
The type of load
˘
The load intensity
