Stepper motors for the EXTREME

Our EXTREME stepper motors are costefficient, clean and reliable even within extreme environments. The EXTREME series are developed and built to resist vacuum, cryogenics, high temperature and radiation while maintaining high performance, precision positioning, long life and low impact on their environment.

The modular, freely programmable motion controller (PMC) for stepper motors

phytron's phyMOTION™ is a modular, freely programmable motion controller for stepper motor applications – from CPU to power stage. With the driving performance of a CNC (linear / circular interpolation), the versatility of a PLC (I/O, modularity, fieldbus interfaces) and phytrons high precision power stage technology for stepper motors, the phyMOTION™ is the ideal controller for stepper motor driven multi-axis platforms in machine building, special engineering and plant automation

The high-precision PLC stepper motor module

The phytron 1-STEP-DRIVE-5A-48V module is a high precision stepper motor control with an integrated power output stage for reliable operation in the SIMATIC® ET 200®S distributed periphery system. The 1- STEP-DRIVE-5A-48V successfully completed the system compliance test performed by Siemens

The integrated power output stage is made for operating with a 2-phase stepper motor up to 5APEAK with a supply voltage from 24 to 48VDC. This versatile control is capable of the same positioning functions as the SIMATIC®-Module ET 200®S 1Step: amongst others are relative and absolute positioning, movement to a reference point and running infinitely rotating axes. The power stage technology is deployed in combination with the patented phytron chopper design to assure minimal heat loss at all times in the module itself as well as in the motor. The high-precision current control by the 1-STEP-DRIVE-5A-48V provides a step resolution up to 1/512 step – a precondition for extremely smooth rotation and high-precision positioning (102,400 positions per rotation). An absolute positioning error of only ~0.0015° can be achieved in micro step operation (1/512 step) by adding an encoder and counter module
