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).
