Softless Brushless Motor Drive

For its customer Zodiac Aerospace, WATT&WEL design a full custom motor inverter and its control dedicated to airplane wipers. Old wipers actuators were fully mechanical (dc motor with crank rod mechanisms). In the more electric airplane, these actuators are brushless DC motor based with a control law for shaft angle.

Ariane 6 equipment- Fault Tolerant Critical Control

The power electronics driving critical actuators in launchers required real time, hot redundant controllers. Traditional platform with 2 controllers (a nominal and a redundant) cannot react fast enough to ensure control continuity. WATT & WELL developed a controller platform achieving these high-performance constraints, using innovative technologies.

Ariane 6 equipment: Fault Tolerant Motor Control

Aerospace systems become more and more electrical. Former hydraulic and mechanics actuators are gradually replaced by electrical actuators. The power electronics and the motor driving critical actuators shall be highly reliable, even if a single failure occurs. WATT&WELL developed a fault tolerant power stage, which is single failure proof.

Ariane 6 Second Stage Motor Pumps Controller

For its customer ArianeGroup, WATT&WELL is developing a motor driver and its embedded controller for a motor pump unit located in the second stage of the future Ariane 6 launcher. This highly critical motor driver is not only fault tolerant to any single failure of the electronics, but also radiation tolerant.

Ariane 6 Second Stage Motor Pumps Controller: Radiation hardening

Radiation Hardening is necessary for an equipment that goes into outer space since exposed to ionizing particles. Radiation can affect equipment in severe ways and these effects need to be counteracted to ensure the good functioning throughout a mission. The CMTP is part of a launcher which’s mission lasts for 2 hours which implies that it is affected by SEE. Our equipment is made radiation tolerant to SEE thanks to our agile electronics solutions.
