home     products     stepper motors    stepper motors – special versions         STÖGRA stepper motors – special versions           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                     SM 87.2.18M6 Z9 IP68                         Version Z177 Generally we recommend to order our IP68 motors with additional special coating for protection against corrosion (see also Special coating against corrosion Z119 / Z177). ordering indication for »Z9« and special coated: Z177 • Ordering example: SM 87.2.18M6 E50 Z177                   Version Z321 A further available version is for salty seawater and environments with chemical additives (e.g. water with chlorine - swimming pools, or water with other aggressive cleaning compounds). This version includes:    - IP68 protection class    - aluminium parts (flange, cast connectionbox, backcover) anodised    - stator surface nickel-plated    - special coating ordering indication: Z321 • Ordering example: SM 87.2.18M6 E50 Z321               Download         stepper motors special versions – data sheet (56 KByte)         stepper motors catalogue 2016 – Catalogue (850 KByte)           stepper motors  I   position controls  I   power amplifiers  I  equipment   I  home  I  info@stoegra.de
