Veronte MC110 motor controller

Veronte MC110 is a liquid-cooled motor controller from Embention for eVTOL aircraft and other electric aircraft, built as a high-voltage inverter that drives the propulsion motor from a battery bus. It belongs to the family of ESCs used for electric propulsion in the heavy-lift and passenger-class range, and is available in a version for supply voltages up to 800 V.

The unit is specified for 110 kW of continuous power. With a supply voltage from 65 V to 800 V it delivers 200 A continuous current and 280 A peak. In use, the continuous figures set the sustained cruise and hover load the controller can carry, while the peak figure covers short demands such as transitions or recovery manoeuvres. Embention builds the power stage with IGBT devices, a mature technology for high-power motor control at moderate switching frequency.

Control is field-oriented (FOC) and works with sensored and sensorless motors, so the same hardware can be paired with different machine designs. Regenerative braking is supported. The controller reports temperature, speed, voltage and input and output current as telemetry, which the flight computer or a battery and propulsion monitoring system can use for health management and limits.

For integration, the controller offers CAN, CAN FD, RS-232, RS-485 and USB communication, plus PWM and discrete input and output lines. These cover connection to Veronte autopilots as well as third-party avionics. The housing measures 175 mm by 320 mm by 97 mm and weighs 2,700 g. Liquid cooling means the unit must be connected to the aircraft's thermal loop, which allows the high continuous power in a compact package.

Embention states design compliance with the DO-178C software and DO-254 hardware standards, and works to aeronautical design practice under its EN 9100 quality system. These references matter for programs that aim at certified electric aircraft, where the propulsion controller needs traceable development.

Typical applications are eVTOL air taxis, regional electric aircraft and large electric uncrewed aircraft that use a high-voltage battery architecture with a direct-drive propulsion motor.
