Phytron GmbH, represented exclusively in the UK by Mclennan, is a globally leading supplier of motion control solutions for extreme environmental conditions. For automation applications where standard-spec motors are just not up to the job, the German manufacturer’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 107 mm with holding torques from 0.45 to 17 Nm. The 2-phase 200-step/rev hybrid stepper motor design has smooth motion, suits unipolar or bipolar operation, and is micro-stepping 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 2- or 3-channel versions. Other customization options include backlash-free planetary gear units with a wide choice of reduction ratios, double or alternative shaft dimensions, adapted mechanical interfacing, electrical modification including terminal box wiring, or extended-length cabling.
Phytron’s ZSH series stepper motors are part of a comprehensive range of standard, harsh, and extreme duty stepper motors, including stainless-steel housed versions, motors and actuators for operation in vacuum and cryogenic tasks, and space-qualified motors. Phytron also offers compatible drives and motion controls. And Mclennan, through its several years’ experience working with Phytron, provides complementary harsh environment customised equipment as part of complete motion sub-systems along with comprehensive support.
Mclennan works closely with a selected number of globally recognised distribution partners, providing motion control and automation solutions from single components to complete systems—including stepper, brushed and brushless servo motors, integrated motors, and many other motor types, along with drives, gear units, positioning stages, motion controllers, software, training, and comprehensive after-sales support.
