Established in 1947, Phytron GmbH is a leading manufacturer in the industry of stepper motors and control devices. Being a customer-oriented high-technology company certified to ISO 9001 and EN13485. Phytron-Elektronik has the process know-how of more than 300 stepper motors in space operations for the successful development of demanding applications.

 

Stepper motor controllers and power stages

 

Phytron’s control units perform, especially in applications that rely on very precise and smooth running behavior. We control motors in electron microscopes, accelerator experiments or also in paper production machines - with up to 1/512 step (102 400 positions per revolution with a 200 step motor). From the power amplifier to the modular, cost-effective multi-axis system we offer the right control concept for your requirements.

 

Stepper Motor Driver

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).

The short-circuit-proof and overload-protected 1-STEP-DRIVE-5A-48V module can be run and parameterized with an ET 200®S CPU as well as with all IM-151 header modules (PROFIBUS and PROFINET compatible). The module can be programmed and parameterized with STEP®7 if either the central interface or the head module supports STEP®7. SIMATIC®, ET 200® and STEP®7 are registered trademarks of the SIEMENS AG.

PhyMOTION Controller

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 phytron’s 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.

Equip every axis individually:

Whatever a stepper motor application requires, besides integrating power stages up to 300 W / axis (5A, 70V), the phyMOTIONT comes with the option to connect more powerful external amplifiers. If it's the housing (bench, rack, rail mounted), a touch screen display, limit and position switches, Endat, SSI or quadrature Encoder evaluation, motor temperature readout (K type or PT100 platinum sensor), I/O (analogue, digital) or host interfaces (Ethernet, RS485, RS232, Profinet, Profibus, CAN) - in addition to these standard components phytron offers the option to integrate customised modules into the system.

The use of our communication protocol is free of any licensing costs and even the development environment phyLOGICTM Toolbox can be downloaded for free.

The phyMOTION™ operates close to the application with CNC-like performance and reacts faster to switch states than customary cycle-based PLCs. The phyMOTION™ is well-equipped for versatile requirements. The programmable motion controller is capable of most diverse division of tasks between phyMOTION™ and the surrounding infrastructure. Whether as a subordinate to a PLC, a decentralised, supporting intelligence, a coordinating stand-alone solution or directly connected to a PC, the phyMOTION™ is capable of comprehensively supplementing a PLC for nearly every stepper motor application. phyMOTION™ - empowering your application.

Stepper Motors

Whether vacuum, cryo environment, high temperature or under the influence of radiation - the phytron motor series are tough and do precision work, because stepper motors can position very accurately without a fragile feedback encoder.

Phytron GmbH combines the flexibility and client-specific consulting from a niche player with the efficiency and standardized quality assurance processes of series production.

Phytron’s control units perform, especially in applications that rely on very precise and smooth running behavior. We control motors in electron microscopes, accelerator experiments or also in paper production machines - with up to 1/512 step (102 400 positions per revolution with a 200 step motor). From the power amplifier to the modular, cost-effective multi-axis system we offer the right control concept for your requirements.

Phytron’s stepper motors are the result of more than 30 years of experience in space technology. The specially designed two phase, hybrid stepper motors can be used in vacuum environments up to 10-11 hPa. They are optimal for extraordinary environments such as deep and high temperatures or extreme radiation intensity.
