BECKHOFF AM3100 - Manual (Page 13)

Drive Technology 6 Technical description
AM3100 Version: 1.4 13
6.3 Standard features
6.3.1 Style
The basic style for the AM3100 synchronous servomotors is IM B5 according to DIN EN 60034-7.
IM B 5 (B5) IM V 3 (V3) IM V 1 (V)
6.3.2 Shaft end, A-side
Power transmission is made through the cylindrical shaft end A, fit h7 according to EN 50347. The bearings are
designed for a service life of 20,000 hours.
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 10.
Axial force
Axial forces arise when assembling pinions or pulleys on the shaft and using angular gearheads, for example.
The permissible maximum values can be found in the technical data.
Coupling
Double-coned 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 h7 accuracy according to DIN 42955
Tolerance class: N
6.3.4 Protection class
Standard version (body), except “V3” IP65
Standard shaft bushing IP40
6.3.5 Insulation material class
The motors conform to insulation material class F according to IEC 60085.
