Akrodyn develops complex systems for Embedded & Robotics: PCB design, firmware, custom motion control, power electronics, safety and edge AI. From test bench to series production.
Akrodyn develops your custom motor controller for servo/BLDC motors with our own high-dynamic, precise control algorithms. From robotics actuators for autonomous vehicles to complex synchronised multi-axis systems, e.g. for X-ray equipment — together we solve your specific challenge. We operate in the custom-made space, but have built a supply chain for you to deliver tens of thousands of controllers at competitive prices.
Control Methods
Proprietary Field Oriented Control+ (FOC+) with PWM up to 100 kHz and current control loop up to 50 kHz. Cost-efficient sensorless operation down to standstill with maximum torque, or optionally with encoder ABI, SSI and BISS-C up to 24 bit for maximum precision. High dynamics and near dead beat control.
Encoder & Feedback
ABI incremental, SSI and BISS-C up to 24 bit resolution. Resolver interfaces, Hall sensor commutation and absolute encoder integration.
Fieldbus Systems
CAN (2.0A/B), CAN-FD, CANopen DS402, RS232/RS485 and EtherCAT with CoE (CiA 402). Real-time synchronisation of multiple drives incl. torque follower.
Multi-Axis & Robotics
Coordinated multi-axis control, Cartesian transformation, impedance control and force control for collaborative robotics actuators.
We design circuits and layouts for power, mixed-signal and control electronics. EMC-compliant, manufacturing-optimised and with complete documentation for production.
PCB Design
2 to 16 layers for high-frequency, power and mixed-signal circuits. Manufacturing-optimised layout, DFM review and complete production files (Gerber, BOM, assembly drawing).
Power Electronics
IGBT, SiC and GaN output stages up to 100 kW. Gate drive design, bus bar routing and thermal management including simulation and power loss measurement.
EMC & Compliance
In-house pre-compliance measurements before formal certification. EMC-compliant layout and support through formal testing to EN 61800-3 C2/C3.
Sensing & Signal Processing
Analogue front-end design, sensor integration and digital signal processing for current, voltage, temperature and torque measurement.
Akrodyn develops firmware for microcontrollers, DSPs and high-performance processors. From hardware initialisation through to secure bootloaders and over-the-air updates.
Embedded Platforms
STM32 (F, G, H, U series), TI C2000 for motor control, Nordic NRF52 for BLE and ESP32 for IoT. Bare-metal and RTOS (FreeRTOS, Zephyr) depending on requirements.
Communication Protocols
EtherCAT with ESI/XML, CAN-FD, BLE 5.x, LoRa/LoRaWAN, USB CDC/HID and MQTT for industrial control and IoT connectivity.
Security & IP Protection
AES-256, RSA, encrypted bootloader design, secure boot and code obfuscation to protect intellectual property from unauthorised readout.
Desktop, HMI & Mobile
Industrial operator interfaces with Qt and PyQt. Mobile apps for Android, iOS and cross-platform with Flutter for commissioning and monitoring.
Akrodyn guides machine and device manufacturers through the entire safety process. From normative analysis and system architecture design through to passed certification with an external testing body. We specialise in the development of test benches. We build and commission them in-house and ship them worldwide.
Normative Foundations
Risk assessment to ISO 12100, performance evaluation to ISO 13849. FMEA, FTA and SISTEMA calculation for safety-relevant control functions.
Safety Architecture
System design up to PLe and SIL 3. Single-channel and dual-channel redundant structures with safe communication and diagnostic functions.
TÜV Support
Guidance through the entire certification process. We establish contact with the selected testing body from the very start, so that their requirements are factored into the design.
EMC Testing
Preparation and support for EMC testing to EN 61800-3 C2/C3 for drive systems in industry and infrastructure.
Your customers want reliable AI devices without a permanent internet connection and backend? Together we build the hardware and adapt AI models for deployment on microcontrollers or embedded Linux systems. We equip the hardware with autonomous functions such as GNSS (GPS) and connect the field devices via LoRaWAN or satellite internet.
TinyML on Microcontrollers
Model compression, quantisation (INT8) and inference on STM32, NRF52 and ESP32. Classification, anomaly detection and prediction without cloud.
Computer Vision
Object detection (YOLO, MobileNet), OCR and semantic segmentation on edge processors. Camera integration, ISP tuning and image preprocessing.
Autonomous Systems
Lidar-based environment perception, multi-sensor fusion (IMU, GNSS, camera) and reactive path planning for mobile platforms and industrial robots.
Connectivity & Field Devices
5G NTN (satellite internet), LoRaWAN and GNSS for self-sufficient IoT devices in remote areas without terrestrial network coverage.
What we develop for ourselves, you can use right away.
Alongside customer projects we build our own hardware and software. You can order brake chopper modules, servo drives and CAN adapters in the shop; engineering tools run free of charge in your browser.
Universal Brake Chopper
Protection against overvoltage in the DC link, 10-999 VDC, up to 80 kW peak power.

What you get at Akrodyn
We don't only build for others.
We have our own products in series production. What we develop for you is the same road we have already walked for ourselves.
Our own EMC test bench.
We measure emissions on the very first samples in our own lab, at a stage where layout changes still cost little.
One team from concept to commissioning.
The people who take down your requirements also develop the electronics and firmware, and stand next to you at the machine during commissioning.
Deep technical competence.
Risk analysis to ISO 12100 and 13849, safety concepts up to PLe and SIL 3, TÜV support and the V-model: not as a slide, but as a way of working and a result.
Structured Development
Together we bring innovative products to market on schedule, inspiring customers and employees alike.
