BECKHOFF AM8100 - Manual (Page 16)

Technical description
Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur.The permissible values at
the shaft end, depending on the speed, may be read from the diagrams in the Section Technical data
[
} 27].Please use the force calculation program available from our website for exact calculation of the radial
Forces.
Axial force
Axial forces arise when assembling pinions or pulleys on the shaft and using angular gearheads, for
example. Please use the force calculation program available from our website for exact calculation of the
axial Forces.
Coupling
Double­coned collets, possibly in association with metal bellows couplings, have proven themselves as
excellent, zero backlash coupling elements.
6.3.3 Flange
Flange dimensions according to IEC standard, fit j6 (h7 at AM811x), accuracy according to DIN 42955
Tolerance class: N
6.3.4 Protection class
Standard version ­ housing IP65 (IP54 = AM811x)
Standard version ­ shaft feedthrough IP54
Shaft feedthrough with shaft sealing ring IP65
6.3.5 Insulation material class
The motors conform to insulation material class F according to IEC 60085 (UL 1446 class F).
6.3.6 Vibration class
The motors are made to vibration class A according to DIN EN 60034­14. For a speed range of 600­3600
rpm and a shaft centre height between 54 ­ 97 mm, this means that the actual value of the permitted
vibration severity is 1.6 mm/s.
Speed [rpm] Max. rel. vibration displacement
[µm] Max. run­out [µm]
