18 Version: 1.5 AM3000 / AM3500
6.3.7 Vibration class
The motors are made to vibration class A according to DIN EN 60034-14. For a speed range of 600-3600 rpm
and a shaft centre height between 56-132 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. run-out [µm]
<= 1800 90 23
> 1800 65 16
6.3.8 Connection technology
The motors are fitted with angular connectors (AM301x: straight connectors at the cable ends) for the power
supply and the feedback signals.
The mating connectors are not included in the scope of supply. We can supply preassembled feedback and
power cables. Information regarding the cable materials can be found in Section 8.2.

Note
Motor length
The motor length depends on the built-in feedback unit, among other factors. Retrofitting is not
possible.
6.3.10 Holding brake
WARNING
Serious risk of injury!
The holding brake is not personal safety. If the brake is released then the rotor can be moved
without a remanent torque!
The AM302x-AM308x and AM35xx motors are optionally available with an in-built holding brake. The AM3000
model features a spring-actuated brake (24 V DC), the AM3500 features a permanent-magnet brake (24 V DC).
When the brake is de-energised it blocks the rotor. The holding brakes are designed as standstill brakes
and are not suited for repeated operational braking.
The holding brakes can be controlled directly by the servo drive (no personal safety!), in which case the brake
winding is suppressed in the servo drive. Additional circuitry is not required.
If the holding brake is not controlled directly by the servo drive, additional circuitry (e.g. varistor) is required.
Consult our applications department beforehand.
Note
Motor length
The motor length depends on the built-in holding brake, among other factors. It is not possible to
fit one at a later date.
