Standard features

I.5.1

Style

The basic style for the 6SM45..100 synchronous motors is style IM B5 according to
DIN42950. The permitted mounting positions may be read from the technical data of the
motor series.
I.5.2

Shaft end, A-side

Power transmission is made through the cylindrical shaft end A (fit k6) to DIN 748, with a
locking thread but without a fitted-keyway.
If the motors drive via pinions or toothed belts, then high radial forces will occur. The per-
missible values at the end of the shaft may be read from the diagram in chapter III.1.2.
The maximum values at rated speed you will find at the technical data. Power take-off
from the middle of the free end of the shaft allows a 10% increase in F
The curves are based on a bearing life of 20.000 operating hours.
Double-coned collets have proved to be ideal zero-backlash coupling devices, combined,
if required, with metal bellows couplings.
I.5.3

Flange

Flange dimensions to IEC standard, fit j6, accuracy according to DIN 42955.
Tolerance class: N (R available as option -65-)
I.5.4

Protection class

Standard version
Motors with separate fan (Option -BV-)
Standard shaft bushing
Shaft bushing with shaft-sealing ring (Option -J-)
I.5.5

Protective device

The standard version of each motor is fitted with a thermostat (electrically isolated,
normally closed). You will find the switching point at the technical data. The thermostat
does not provide any protection against short, heavy overloading. Provided that our pre-
assembled resolver cable is used, the thermostat contact is integrated into the monitoring
system of the digital servo-amplifier digifas® or SERVOSTAR™.
The flange temperature must not exceed 65°C in rated operation.
