4.1.5 Bearings
The motors are equipped with permanently greased deep-groove ball bear‐
ings. The fixed bearing is on the B-side. The nominal bearing lifetime L
10h
is
30,000 h under consideration of the shaft and bearing load specified in the
project planning description.
4.1.6 Cooling
Natural convection
The nominal data are achieved at ambient temperatures of up to 40 °C. Suffi‐
cient heat radiation must be ensured by the installation situation. Unhindered
vertical convection has to be ensured by a sufficient distance of 100 mm to
adjacent components on the side surfaces. Pollution of the surface of the mo‐
tor reduces heat dissipation and can result in thermal overload, see chapter
12 "Troubleshooting " on page 48 .
Surface ventilation
Cooling is realized by external radial (LEM-RB) or axial (LEM-AB) fan units.
Please also observe the additional information on holding brakes in and .
DOK-MOTOR*-MSK********-PR··-··-P, "Synchronous Servomotors MSK".
Contamination can reduce the flow rate of the fans and lead to thermal over‐
load of the motors. For cooling use clean ambient air only. Heated air may
not be sucked in again.
The use of the fan under the following conditions is expressly not suitable:
●
Delivery of air which contains abrasive particles
● Delivery of air which has a strongly corroding effect, e.g., salt mist
