Stepper motors for extended operating temperature range – options Z80 and Z240

The operating temperature range for all STÖGRA standard motors is -30°C until 80°C permanently (short time 100°C).
This max. allowed temperature at the motor surface (measured at stator housing - backside near the cast connection box) may not
exceeded. The motor temperature reached during operation depends from various factors:
e.g. motor current, motor speed, ambient temperature, duty cycle, forced draft, heat flow from motor to other bodies, ...

For extreme applications STÖGRA offers motors with extended operating temperature:

type  temperature range

Z240  -30°C until 100°C (short time until 120°C)
Z80  -30°C until 120°C (short time until 130°C)

Ordering examples: SM 87.2.18M6 Z240, SM88.1.18M4 Z80

STÖGRA also offers further versions, e.g. for low temperature until -50°C – please contact us.

IP68 Motor
Version Z9

All motor series from STÖGRA are available optionally with protection class IP68. The IP68 motors
are tested under water with 1 bar pressure (corresponds to operation of motor in 10m water depth).
Typical applications for IP68 motors are, beside underwater are any plants outside (e.g. faced to rain)
or in the food industry, where motors are cleaned with water. The motors include special sealings
and some special parts as special flanges). Options »brake« and »encoder« are also possible for
IP68 motors. IP68 motors need to be ordered with the extension Z9 in the type designation.
- Ordering example : SM 87.2.18M6 E50 Z9

Motors with special coating for protection against corrosion Z119 / Z177

All STÖGRA motors are available optionally with special coating.
The complete motor surface will be primed two times and then specially coated.
This guarantees an extremely robust protection of the complete motor surface against corrosion.
Typically motors in IP68 version (see above Z9) or motors in IP55 (standard cast connection box version) for the food industry are ordered in special coated version.

Coated motors in IP55 (standard cast connection box) must be ordered with the extension Z119.
-  ordering example: SM 87.2.18M6 E50 Z119

Coated motors in IP68 version (see above »Z9«) must be ordered with the extension Z177.
