These operating instructions contain information about the
transport, installation and commissioning of STOBER EZ,
EZF, EZH, EZHD, EZHP synchronous servo motors and EZS,
EZM synchronous servo motors for screw drive.
For further details, see catalogs SMS-EZ (ID 442212) and
EZS/EZM synchronous servo motors for screw drive (ID
442416).
In the event of any unclear points, we recommend that you
contact STÖBER with the model designation and serial
number, or have the installation and maintenance work
carried out by a STÖBER service partner.
1
Operation in accordance with its
intended use
Synchronous servo motors must be used exclusively for
operating machines and systems together with servo
inverters.
Stay within the limits defined by the technical data.
Do not use synchronous servo motors in potentially explosive
atmospheres.
For reasons of operational safety, motors may only be used
for the single application for which they were projected.
Any overload on the drives is considered unintended use.
The information and instructions in these operating
instructions must be precisely followed to ensure that claims
submitted under the warranty will be honored. If modifications
are made to motors, warranty claims will be rendered void.
Comply with the safety instructions in these operating
instructions and in all supplementary documents for the
synchronous servo motor and other components such as
gear units and servo inverters.

Technical data
The technical data for synchronous servo motors, geared
motors and servo inverters that are used is indicated on the
relevant nameplates.
Acceleration / shock load in operation:
The following value for the shock load indicates the value up
to which the motor can be operated without loss of
functionality: 50 m/s² (5 g), 6 ms (maximum value as per DIN
EN 60068-2-27).
Brace the motor connection cable close to the motor so that
vibrations of the cable are not transferred to the motor.
When connecting the motors to drive units such as gear units
or pumps, take into consideration the permissible shock loads
and tilting torques of the units.
NOTICE
Damage to the motor.
X
Prevent undue force on the motor such as impact, shock,
pressure or high acceleration.

∆
T = 100 K
Surrounding
temperature:
-15 °C to +40 °C (with water c5
°C to +40 °C)
Installation altitude: up to 1000 meters above sea level
Cooling:
For IC 410 convection cooling;
or optional IC 416 convection cooling
with forced ventilation (DIN EN 60034-
6), see 2.4.1;
or optionally for water cooling in the A-
side motor flange, see 2.4.2
Surface:
Black matte as per RAL 9005
Please note! Repainting will change
the thermal properties and therefore
the performance limits of synchronous
servo motors.
Vibration intensity: as per DIN EN 60034-14 degree N
(half wedge balancing for shafts with
key).
Winding:
Connection wires: U (U1) - black, V
(V1) - blue, W (W1) - red.
Connection
method:
see motor connection diagrams
Information
If brakes are installed, the holding torques may
be reduced by the shock load!
