BECKHOFF AM8000 - Manual (Page 16)

6 Technical description Drive Technology
16 Version: 2.4 AM8000 and AM8500
6.3 Standard features
6.3.1 Style
The basic style for the AM8000 and AM8500 synchronous servomotors is IM B5 according to DIN EN 60034-7.
IM B 5 (B5) IM V 3 (V3) IM V 1 (V1)
The permitted mounting positions are specified in the technical data.
Attention
Motor damage
To avoid liquid entry damaging the motor, fluids (i.e. used for cleaning purposes) must be
removed from shaft when motor is mounted according to IM V3.
6.3.2 Shaft end, A-side
Load transmission occurs force locked (zero-play) with a clutch on the cylindric end of the shaft A or optionally
by keyed connection with feather key groove according to DIN 6885. The lifecycle of the bearings is 30.000
operating 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. Please use the force
calculation program “Beckhoff AM8000-Motors Radial forces, life cycle” 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 “Beckhoff AM8000-Motors Radial forces, life cycle” available from our
website for exact calculation of the radial forces.
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 j6 (h7 at AM801x), accuracy according to DIN 42955
Tolerance class: N
6.3.4 Protection class
Standard version - housing IP65 (IP54 at AM801x)
Standard version - shaft feedthrough IP54
Shaft feedthrough with shaft sealing ring IP65
6.3.5 Overtemperature protection
The standard version of each motor (not AM801x) is fitted with a KTY 84.130.
Provided our preassembled motor cable is used, the KTY is integrated into the monitoring system of the digital
servo amplifiers. Please configure the servo drive such that a motor temperature warning is issued at 100 °C
and the motor is switched off at 140 °C.
6.3.6 Insulation material class
The motors conform to insulation material class F according to IEC 60085 (UL 1446 class F).
