How It Works
The Mil-Drive-55 Military Motor Drive and Control Unit operates based on an intelligent motor control architecture developed by TEDEG Defense.
The system processes power, I/O signals, and sensor feedback received from the platform in real time, forming a dynamic control algorithm (FOC – Field Oriented Control) internally.
Through this algorithm, the Mil-Drive-55 continuously optimizes motor speed, torque, and directional parameters according to mission scenarios, providing high-precision and stable motor control under all operating conditions.
- Input Stage – Power and Signal Acquisition
The Mil-Drive-55 FOC motor drive receives 230/400 VAC power input and analog/digital I/O signals from the platform.
These include resolver or encoder feedback, NTC temperature sensors, emergency stop, Safe Torque Off (STO), RS-485, and CAN-Bus communication lines.
The device analyzes these signals through high-speed ADC and DSP processors, determining the motor’s real-time operating status.
At this stage, the TEDEG motor control system filters and isolates all incoming signals, suppressing electromagnetic interference (EMI) to ensure clean data flow.
This design enables stable and safe operation, particularly in MIL-STD-810G / MIL-STD-461F compliant military environments.
- Processing Stage – Embedded Software and Control Loop
At the core of the device lies an MCU-based control board that executes the FOC (Field Oriented Control) algorithm.
This control unit continuously measures current and voltage across the motor windings, resolves the magnetic field vectorially, and manages the speed–torque relationship with extreme precision.
The Mil-Drive-55 Military Motor Drive performs thousands of control operations per second, forming a high-frequency closed-loop system.
In each cycle, the controller:
- Calculates rotor position in real time,
- Adjusts motor current relative to reference torque,
- Applies dynamic corrections based on feedback sensors.
As a result, the motor maintains stable, low-noise, and efficient performance, even under sudden load or directional changes.
This real-time processing chain represents the core of the intelligent motor control unit software, setting the Mil-Drive-55 apart from conventional drives.
- Output Stage – Precision Motor Drive
The processed control signals are transmitted to a three-phase IGBT-based inverter module.
This inverter regulates the voltage and current delivered to the motor windings through PWM (Pulse Width Modulation) control.
The result is precise torque and speed generation with over 90% energy efficiency.
Each motor output is electrically isolated, ensuring EMC compatibility with other onboard electronic systems.
This makes the Mil-Drive-55 FOC motor drive ideal for servo motor applications in radar systems, electro-optic turrets, missile platforms, and armored vehicles, providing clean, stable, and interference-free power transfer.
- Safety and Protection Stage – STO and System Monitoring
The Mil-Drive-55 IP67 motor drive incorporates the Safe Torque Off (STO) safety function to ensure mission safety.
