6.4 Options

Holding brake

The holding brake is integrated in the motor. It increases the motor length.

Radial shaft-sealing ring

Radial shaft-sealing ring (Teflon) for sealing against oil mist and oil spray. This increases the protection class of

the shaft bushing to IP67.

Feather key

The motors are available with feather key groove and fitted feather key according to DIN6885. The rotor is

balanced with half a feather key.

EnDat (only AM30xx), BiSS

This model features a different feedback system in place of the resolver, which may result in an increase of the

motor length.

Note

Installation options and reduction of rated values

With the exception of the sealing ring, the options cannot be retrofitted.

Options such as sealing ring, holding brake, EnDAT or BiSS can lead to a reduction of the rated

data.

6.5 Selection criteria

The three-phase servomotors are designed for operation with servo drives.

Both units together form a speed or torque control loop.

The main selection criteria are:

— Standstill torque M0 [Nm]

— Rated speed at rated supply voltage nn [min-1]

— Moment of inertia of motor and load J [kgcm²]

— Effective torque (calculated) Mrms [Nm]

The static load and the dynamic load (acceleration/braking) must be taken into account in the calculation of the

required motors and servo drives. Formulas and calculation example are available from our applications

department on request.
