Harsh environment stepper motors

For automation applications where standard specification motors are just not up to the job, Phytron GmbH’s ZSH-series stepper motors are aimed at the toughest industrial settings including maritime and chemical industries, oil and gas, agricultural and construction machinery, biogas and energy production, and more.

The NEMA compatible ZSH-series is available in frame diameters of 57, 87 and 107mm with holding torques from 0.45 to 17Nm. The two-phase 200 step/rev hybrid stepper motor design has smooth motion, suits unipolar or bipolar operation and is microstepping compatible. Standard ZSH motors have IP54 protection and an extended surface temperature range from -30°C to +80°C (briefly to 100°). An optional IP68 protection class facilitates operation in climatic chambers or submerged in aggressive liquids such as fuel oils or detergents.

A comprehensive range of options with harsh-environment specifications include integral permanent magnet brakes and a choice of feedback encoders with resolution options of 50, 200 or 500 lines in two- or three-channel versions. Other customisation options include backlash-free planetary gear units with a wide choice of reduction ratios, double or alternative shaft dimensions and adapted mechanical interfacing, also electrical modification including terminal box wiring or extended length cabling.
