Enabling high-performing motor control solutions for UAVs

Reflex Drive, a deep-tech startup from India, has selected power devices from Infineon Technologies AG for its next-generation motor control solutions for unmanned aerial vehicles (UAVs). By integrating Infineon's OptiMOS 80V and 100V, Reflex Drive's ESCs attain improved thermal management and higher efficiency, enabling high power density in a compact footprint. Additionally, the use of Infineon's MOTIX IMD701 controller solution, which combines the XMC1404 MCU with the MOTIX 6EDL7141 3-phase gate driver IC, delivers compact, precise, and reliable motor control. This allows improved performance, greater reliability, and longer flight times for UAVs.

"Our partnership with Reflex Drive is an important contribution to our market launch strategy and presence in India," says Nenad Belancic, global application manager of Robotics and Drones at Infineon. "Our partner has proven its expertise with numerous customers who have obtained aviation certifications. In addition, the company has presented its innovative technologies enabled by Infineon systems at important international industry events."

"Our collaboration with Infineon has led to significant advances in UAV electronics," says Amrit Singh, founder of Reflex Drive. "We believe drones have the potential to transform industries, from agriculture to logistics, and with Infineon's devices, we can help drive this transformation at the forefront."

Reflex Drives's ESCs with field-oriented control (FOC) provide improved motor efficiency and precise control, while its high-performance BLDC motors are designed for optimised flight control and enable predictive maintenance of drive systems. Weighing only 180g and with a compact volume of 120cm³, the ESCs can deliver a continuous power output of 3.8kW (12S/48V, 80A continuous). Due to their lightweight design, robust power output, and consistent FOC control – even under demanding weather conditions – they make excellent motors for the thrust range of 15kg to 20kg. Therefore, they are particularly suited for drone applications in fields such as agricultural spraying technology, seed dispersal, small-scale logistics, and goods transportation.
