Technical data
Notes regarding the given data
Catalog data
The power, torque, and speed values specified in the configuration are rounded values and
apply for
•
Operating time per day = 8 hrs (100 % ED)
•
Duty class up to 10 switching operations per hr
•
T
U
= 40 °C
•
Site altitude ≤ 1000 m above sea level
•
The selection tables indicate the mechanically permissible power levels and torques.
•
The ratings apply to the operating mode S1 (acc. to EN 60034).
NOTICE
In case of other operating conditions, the achievable values can differ for those mentioned.
▶
In case of extreme operating conditions, please contact your responsible Lenze sales
company.
Thermal power limit
The thermal power limit, defined by the heat balance, limits the permissible permanent
gearbox power. It is affected by:
•
the churning losses in the lubricant. These are determined by the mounting position and
the circumferential speed of the gears
•
the load and the speed
•
the ambient conditions: temperature, air circulation, input or dissipation of heat via shafts
and the foundations.
NOTICE
A thermal check with the Drive Solution Designer (DSD) contacting the Lenze office
responsible for you is required if
▶
the input speed n
1
> 1500 rpm is exceeded in case of the gearbox ratios given in the
following.
▶
The drive speeds given in the following are exceeded as a function of the mounting position.
Temporarily up to 5 min, 30 % higher speeds are permissible.

Possible ways of extending the application area
•
Shaft sealing ring made of FKM material/Viton (option)
•
Reducing the lubricant amount (after consultation with Lenze)
•
Cooling the geared motor by means of air convection on the machine/ system
