FOC vector-control drives for three-phase induction motors
Three-phase induction motors move the turrets, radar antennas, launcher pedestals and hydraulic pumps of military systems. The drives in this category run those motors with FOC (field oriented) vector control: speed and torque are set through the variable frequency and voltage applied to the motor, starts and stops are ramped, and motor and drive stop safely on a fault. Both products are designed and manufactured by TEDEG in Ankara.

About Military Motor Drives & Motor Control Units
Which product for which need?
- Induction motors up to 5.5 kW, a wide frequency range and functional safety: Mil-Drive-55 Military Induction Motor Drive — 3 × 400 VAC, 0–500 Hz output, 14 A motor current, dual-channel STO, resolver and encoder inputs, RS-485 and CAN-Bus; optionally up to 18 kW
- Motors up to 4 kW in a sealed enclosure, with interlock and limit inputs and a web interface: Mil-Drive MCU-400 Military Motor Control Unit — 3-phase 400 VAC, 10 A rms (≈ 6.9 kVA), 0–50 Hz, 1024 PPR encoder feedback, RS-485 + Ethernet, 7 × MIL-DTL-38999 connectors, IP67
- Manual control of the MCU-400 in the field: the Mil-Drive HCU-400 pendant control unit is in the control panels and operator units category
What to check when choosing a motor drive: motor power and current, the required speed range (motor frequency), the type of speed feedback (encoder or resolver), safe-stop requirements (STO, emergency stop), the communication interface, enclosure protection and operating temperature. The drive input must match the platform's grid or generator; both products run from 3-phase 400 VAC.

FAQ
How do I choose between Mil-Drive-55 and MCU-400?+
If the motor is above 4 kW, needs a motor frequency above 50 Hz, or your specification calls for dual-channel Safe Torque Off (STO) and a resolver input, choose the Mil-Drive-55: 5.5 kW, 0–500 Hz, RS-485 and CAN-Bus. For motors up to 4 kW that work with interlock and limit inputs, need monitoring over Ethernet and a web interface and sit in an IP67 sealed enclosure, choose the MCU-400; it is used with the HCU-400 pendant control unit for control in the field.
Which motors do they work with?+
Both drives are designed for three-phase asynchronous (induction) motors. The Mil-Drive-55 supports resolver, incremental and absolute encoder and NTC temperature sensor inputs; the MCU-400 runs closed-loop speed control with a 1024 PPR incremental encoder. Motor power, pole count and feedback type are confirmed against the motor nameplate at quotation stage.
How does the drive stop the motor safely?+
The Mil-Drive-55 has dual-channel Safe Torque Off (STO) and an emergency input: STO removes the energy that produces torque in the motor. On the MCU-400, interlock and limit inputs restrict movement, and the emergency stop and fault reset controls on the HCU-400 pendant connect to the unit.
Is a motor drive the same as a frequency converter?+
They are built in a similar way: both produce frequency and voltage with power electronics. The difference is in use. A motor drive changes the frequency continuously to suit the motor's speed and load; a 400 Hz frequency converter gives equipment a fixed 400 Hz or 60 Hz supply. For a 400 Hz supply see military frequency converters.
What can be adapted to the project?+
Power level, additional I/O channels, communication protocol, connector type and cable lengths are set per project. Thanks to its modular design, the Mil-Drive-55 can optionally be configured up to 18 kW.
