| STÖGRA STEPPER MOTORS – SPECIAL VERSIONS |
| Stepper motors for extended operating temperature range – option Z80 and Z240 | |
| For all STÖGRA standard motors the specified operating
temperature range is -30 deg C until 80 deg C permanent operation (short time 100 deg C). This maximum temperature allowed may not be exceeded at the motor surface (measured at the stator housing – near the cast connection box). The motor temperature reached during operation, depends on various factors: e.g. motor phase current, speed, ambient temperature, duty cycle, forced draft, heat flow to other bodies, ... For extreme appliactions STÖGRA offers motors with extended operating temperature: Typ Temperature range Z240 -30 deg C until 100 deg C (short time until 120 deg C) Z80 -30 deg C until 120 deg C (short time until 130 deg C) Ordering examples: SM 87.2.18M6 Z240, SM 88.1.18M4 Z80 STÖGRA also offers further versions , e.g. for low temperature applications until -50 deg C. Please contact us for details. |
| Shaft modifcations for STÖGRA stepper motors series SM 87 and SM 88 – option Z8 and Z200 | |
| Series SM 87 in »M«-version (metrical dimensions) includes
in standard version a shaft diameter of 10mm (dimension D2 in the dimensions drawings in stepper motor catalogue page 5). Series SM 88 in standard version includes a shaft diameter of 12mm. Optionally motors SM 87 and SM 88 are available with following shaft diameters (dimension D2): SM 87 with 12mm: ordering indication SM 87... M...Z8 (e.g. SM 87.2.18M4,6 Z8) SM 88 with 10mm: ordering indication SM 87... M...Z200 (e.g. SM 88.2.18M8 Z200) Also other customer specific shaft diameters and modifications are possible. |
| Metalic rear cover for STÖGRA stepper motors series SM 87 and SM 88 – option Z48 | |
| In standard version series SM 87, SM 88 and SM 107 are delivered
with a PVC back cover. Only SM 56 and SM 168 are delivered in standard version with metalic back cover. Optionally series SM 87, SM 88 and SM 107 also are available with metalic back cover (aluminium) – option Z48. The metalic cover may be used e.g. for mounting of an external encoder at motors with second shaft end. Ordering example: SM 87.3.18M3,5W Z48 |
| Vacuum compatible motors series SM ... V and SM ... V Z138 | |
| For vacuum and clean room applications we offer our vacuum
compatible series SM ...V and SM ...V Z138. Specifications: |
| – vakuum compatible until 10-6 Torr | ||
| – blank stator surface | ||
| – vacuum compatible special bearing grease | ||
| – for leads motor versions including teflon leads | ||
| – metalic back cover (aluminium) | ||
| – motors are not gased out! | ||
| ordering example: SM 87.3.18M6V The option Z138 additionally includes a galvanically nickled motor surface (protection against corrosion for the blank stator). Ordering example: SM 87.3.18M6V Z138 These options are available for all STÖGRA motors. |
| IP68 Motors – Z9 and Z177 | ||
| 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 Generally we recommend to order our IP68 motors with additional special coating for protection against corrosion (see also below Z119 and Z177). Ordering key for Z9 and special coated: SM ...Z177 Ordering example: SM 87.2.18M6 E50 Z177 |
| 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 (standardcast 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«. Ordering example: SM 87.2.18M6 E50 Z177 Motors usable in sea water environment are also available (please contact us for more informations). |
