I.5.6
Insulation material class
The motors come up to insulation material class F according to DIN 57530.
I.5.7
Vibration class
The motors are made to vibration class N according to DIN ISO 2373.
I.5.8
Connection method
The motors are fitted with rectangular connectors for resolver signals and terminal boxes
for the power supply. The mating connectors are not part of the delivery package.
We can supply preassembled resolver and power cables (

I.5.9
Resolver
The motors are equipped with two-pole hollow-shaft resolvers.
I.5.10
Holding brake
The motors are optionally available with a holding brake.
Type designation:
6SMxxx-xxxx
-G
A permanent magnet brake (24V DC) is integrated into the G-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 remanent torque, the operation is free from backlash!
The holding brake can be controlled directly by digifas® or SERVOSTAR™-servo-ampli-
fier (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. varistor) 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.

Selection criteria
The three-phase servomotors are designed to operate with digifas® or SERVOSTAR™
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 formula and examples
of the calculations are available from our applications department.
