Technical Description
6.3
Standard features
6.3.1
Style
The basic style for the AM3000 synchronous motors is style IM B5 according to DIN EN 60034-7.
The permitted mounting positions may be read from the technical data of the motor series.
6.3.2
Shaft end, A-side
Power transmission is made through the cylindrical shaft end A, fit k6 (AM301: h7) to DIN 748, with
a locking thread but without a fitted-keyway.
Bearing life is calculated with 20.000 operating hours.
Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur. The permissible
values at the end of the shaft may be read from the diagrams in chapter 10. 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
Axial force
When assembling pinions or wheels to the axis and use of e.g. angular gearheads axial forces
arise. The maximum values at rated speed you will find at the technical data.
Coupling
Double-coned collets have proved to be ideal zero-backlash coupling devices, combined, if requi-
red, with metal bellows couplings.ve proved to be ideal zero-backlash coupling devices, combined,
if required, with metal bellows couplings.
6.3.3
Flange
Flange dimensions to IEC standard, fit j6 (AM301: h7), accuracy according to DIN 42955.
Tolerance class: N
6.3.4
Protection class
Standard version
Standard shaft bushing
Shaft bushing with shaft-sealing ring
6.3.5
Protective device
The standard version of each motor is fitted with an electrically isolated PTC (rated temperature
155°C ± 5%). The PTC does not provide any protection against short, heavy overloading. Provided
that our preassembled resolver cable is used, the PTC is integrated into the monitoring system of
the digital servo amplifiers.
6.3.6
Insulation material class
The motors come up to insulation material class F according to IEC 60085.
