I.6 Options
— Holding brake
Built-in holding brake ( Þ I.5.10).
Motor length increases by the holding brake.
— Radial shaft-sealing rings
A radial shaft-sealing ring can be supplied at extra charge to seal against oil mist
and oil spray. This increases the protection rating of the shaft bushing to IP65. The
sealing ring is not suitable for dry running. When a holding brake is built in, the
motor length increases by a sealing ring for approximately 10mm.
— Vertical mounting sockets
If fitted with angular sockets for feedback and power connectors, the motors are
also available with vertical sockets.
— Keyway
The motors are available with keyway and key inserted according to DIN748
The shaft is balanced with a short (half) key.
— EnDat
A high resolution EnDat-encoder is mounted instead of the resolver ( Þ I.5.9).
the motor length increases by the encoder.
— 2nd Thermostat
An additional thermostat can be applied to the motor winding. The connection
takes place via the power connector resp. the terminal box.
— Forced ventilation
For some motors ventilation bonnets are available wich cool the motor electrically.
Connection takes place via a 6-pole angular socket
With the ventilation bonnet mounted, the dimensions and nominal data of the
motors vary. Please consult our applications department.
All options can not be retrofitted.
I.7 Selection criteria
The three-phase servomotors are designed to operate with SERVOSTAR™ 600
servo-amplifiers. Together, both units form a closed speed or torque control loop.
The most important selection criteria are:
— Standstill torque M
0
[Nm]
— Rated speed n
n
[min
-1
]
— Moment of inertia of motor and load J [kgcm²]
— Effective torque (calculated) M
rms
[Nm]
When calculating the motors and servo-amplifiers which are required, take account of the
static load and the dynamic load (acceleration/braking). Collected formulae and examples
of the calculations are available from our applications department.
