General information
Thermal power limit
The thermal power limit, defined by the heat balance, limits the permissible continuous
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 spectrum.
•
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) or contacting your Lenze
representative is required if
▶
the input speed n
1
> 1500 rpm is fallen below in case of the gearbox ratios given in the
following.
▶
the drive speeds mentioned in the following will be exceeded as a function of the mounting
position. For a short period of time up to 5 min, 30 % higher speeds are permissible.
▶
the ambient temperature is predominantly above +30 °C.
Gearboxes Ratio i

Motor Mounting position M1 Mounting position M3, M5, M6 Mounting position M2, M4
m850-S120 4000 rpm 3500 rpm 3000 rpm
m850-S140/S190 3000 rpm 2600 rpm 1500 rpm
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 air convection on the machine/system
