Phytron GmbH Stepper motor technology for special requirements: Stepper motor technology is particularly suitable for precision applications under extreme environmental conditions. Whether vacuum, cryo environment, high temperature or under the influence of radioactivity - the Phytron motor series are tough and do precision work, because stepper motors can position very accurately without a fragile feedback encoder. Our control units perform, especially in applications that rely on very precise and smooth running behaviour. We control motors in electron microscopes, accelerator experiments...

INDUSTRIAL Environments Precise. Reliable. Dynamic. Phytron‘s STANDARD industrial motors are eminently suitable for applications in engineering and industry. Whether it‘s for the positioning of slides, the adjustment of pressure rollers or sensitive optics, the synchronised delivery and application of labels or for handling in mail sorting - fast and reliable running performances are constantly demanded. Precision, high torque and solid craftsmanship make our standard industrial motors an excellent choice for environments up to IP 50. Precision stepper motor with smooth running, IP 40, 19...

For Applications with Extended Temperature Range The proven 2-phase hybrid stepper motors series ZSS combine highest precision with smooth running characteristics. With up to 102.400 approachable positions (200-step motor, driven in micro stepping mode with 1/512 step resolution and encoder) the ZSS motor provides your application with highest precision positioning capabilities. Perfect-fit for your application: The ZSS serie differs from standard market motors by the extended ambient temperature range from -30 to +80 °C. • with encoder • with gear - GPL low-backlash planetary gears PLG...

Electrical Connection / Connection Types / Phase Current Phase currents The Phytron stepper motors type ZSS are built in 8-lead windings (standard). For ZSS Phytron stepper motors, the rated current [A] per motor phase is printed on the rating plate. The last digits of the motor‘s type number define the rated current. Example: ZSS 32.200.1,2 The rated current is defined for full step operation, at bipolar control mode, with parallel connected motor windings. According to the connection mode, the motor windings receive different currents. Therefore, for identical power dissipation in the...

Industrial ZSS Stepper Motor with HD Gear The Harmonic Drive® gears are based on a totally new operating principle. The transmission force is exerted by a resilient deformable toothed steel cylinder flexspline which transmits the motor rotation to the drive shaft. Drive shaft and output shaft direction is are opposed. Backlash and torsional stiffness Harmonic Drive® gears have particularly low backlash. In practice, the tooth-contour backlash can be neglected (see page 9). The total gear torsion is equal to the sum of ½ backlash + torque/resillient constant. with mounted stepper motor ZSS...
