Power torque and speeds
The values for power, torque and rotational speed given in
the catalogue are rounded values and apply to
• Running time/day = 8 h (100% DT)
• Duty class I at 10 switching operations/h
• Mounting positions and models in this catalogue
• Standard lubricant
• f mains = 50 Hz constant
• T U = 20 °C for gearboxes
40 °C for motors (to VDE 0530)
• Installation height < = 1000 m above sea level
The rated power specified for motors and geared motors
applies to operating mode S1 in accordance with
VDE 0530 Part 1/DIN 57530 Teil 1.
If your operating conditions differ the values that can be
obtained may deviate from those specified.
If you are operating under extreme conditions, please
contact your nearest Lenze representative.
Load capacity c of gearboxes
Characteristic value for the load capacity of Lenze
gearboxes and geared motors.
– c is the ratio of the permissible rated torque of the
gearbox to the rated torque supplied by the drive
components (e.g. the built-in Lenze motor).
– The value of c must always be greater than the value of
the operating factor k calculated for the application.
Operating factor k (to DIN 3990)
This factor takes into account the influence of actually
existing and changing loads applied to gearboxes and
geared motors over their running time.
k is determined by
– The type of load
– The load intensity
– Temporary factors
