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 between 56-132mm, this means that the actual value of the per-
mitted vibration severity is 1.6mm/s.
Velocity [rpm]
<= 1800

Connection method
The motors are equipped with angular connectors (AM301: straight connectors at cable ends) for
power supply and feedback signals .
The mating connectors are not part of the delivery package. We can supply preassembled resolver
and power cables. On page 18 you will find notes on the cable materials.

The motor length depends on the mounted feedback unit. Retrofitting is not possible.

Holding brake
The AM302-AM307 motors are optionally available with a holding brake.
A spring applied brake (24V DC) is integrated into the motors. When this brake is de-energized it
blocks the rotor. The holding brakes are designed as standstill brakes and are not suited for
repeated operational braking. If the brake is released then the rotor can be moved without a rema-
nent torque. The motor length increases when a holding brake is mounted.
The holding brake can be controlled directly by AX2000-servo amplifier (no personal safety !), the
winding is suppressed in the servo amplifier — additional circuitry is not required.
If the holding brake is not controlled directly by the servo amplifier, an additional wiring (e.g. varis-
tor) is required. Consult our applications department beforehand.
A personal safe operation of the holding brake requires an additional contact (normally opened) in
the braking circuit and an anti-surge-device (e.g. Varistor) for the brake.
