Hydromea Unveils D-FIN™: A Cutting-Edge ESC Motor Controller for Robotic Vehicles.

Lausanne, Switzerland – March 13, 2025

Hydromea, a pioneer in underwater robotics and wireless communication, is proud to announce the launch of its newest product, the D-FIN™ Electronic Speed Controller (ESC) Motor Controller. This state-of-the-art device is engineered to deliver unparalleled efficiency, compactness, and precision for brushless permanent magnet DC (BLDC) motors and thrusters.

The D-FIN™ controller is engineered in Switzerland to offer unmatched compact power and precision for Hydromea’s unique DISKDRIVE™ thrusters and many other brushless permanent magnet DC (BLDC) motors in the robotics and equipment space. This advanced controller brings smooth, silent, and efficient performance to your motors. To fit into the smallest robotic vehicles, it can be stacked on a proprietary backplane to optimize space constraints and reduce cabling. Multiple digital interfaces provide flexibility to integrate D-FIN™ into your system with ease. D-FIN™ can be controlled and monitored via RS485 serial bus, CAN bus, USB-C, or PWM.

Key Features of D-FIN™:

Compact Design: Measuring just 83 x 62 x 12 mm and weighing 80 grams, D-FIN™ is engineered for applications where space and weight are critical.
Wide Input Voltage Range: Supports input voltages from 10 to 36 V, offering versatility across various power systems.
High Current Handling: Capable of managing up to 25 A of current, ensuring robust performance for demanding applications.
Flexible Communication Interfaces: Offers RS485, CAN bus (configurable), USB-C (virtual serial port), and PWM interfaces for seamless integration with diverse systems.
Advanced Control Modes: Supports multiple communication modes, including hall-sensor trapezoidal, hall-sensor Field-Oriented Control (FOC), sensorless trapezoidal, and sensorless FOC, along with a self-calibration mode.

Felix Schill, Co-Founder and CTO of Hydromea, commented on the launch: "As many robotics developers, we’ve been frustrated with the unavailability of a compact, efficient, and precise ESC motor controller in the market. So we developed one for our own thrusters. The D-FIN™ ESC Motor Controller represents a significant advancement in marine motor control technology. Its compact size, high efficiency, and versatile integration capabilities make it an ideal solution for enhancing the performance of robotic systems and many other equipment that requires precise control of BLDC motors."

Hydromea continues to lead in marine innovation, as evidenced by recent developments such as the EXRAY™ underwater inspection ROV equipped with proprietary LUMA™ wireless communication technology. The introduction of D-FIN™ further solidifies Hydromea's commitment to providing cutting-edge solutions for marine exploration and inspection.
