Electronic Speed Controllers (ESC)
Discover cutting-edge solutions from 9 leading global suppliers
Hydromea, an underwater robotics company, has introduced its latest innovation, the D-FIN™ Electronic Speed Controller (ESC) Motor Controller.
This advanced device is designed to provide unmatched efficiency, precision, and compactness for brushless permanent magnet DC (BLDC) motors and thrusters.
Developed and manufactured in Switzerland, the D-FIN controller offers exceptional power and precision tailored for Hydromea’s proprietary DISKDRIVE™ thrusters as well as a wide range of other BLDC motors commonly used in robotics and related technologies.
The controller is engineered to deliver smooth, quiet, and highly efficient performance, making it an ideal choice for demanding applications in robotics and marine exploration. Its compact size ensures it can be easily integrated into the smallest robotic vehicles, with the added benefit of being stackable on a proprietary backplane to optimize space and reduce cabling complexity. With multiple digital interfaces, the D-FIN is versatile and easy to incorporate into existing systems. It supports control and monitoring via RS485 serial bus, CAN bus, USB-C, or PWM, providing maximum flexibility.
Felix Schill, Co-Founder and CTO of Hydromea, stated, “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.”
Key Features of the D-FIN ESC Motor Controller:
- Compact Form Factor: Measuring just 83 x 62 x 12 mm and weighing only 80 grams, the D-FIN™ is ideal for space-constrained applications where weight and size are crucial.
- Wide Input Voltage Range: The controller supports input voltages from 10 to 36 V, offering versatility across a variety of power systems.
- High Current Capacity: Capable of handling up to 25 A of current, D-FIN™ delivers reliable and robust performance for demanding applications.
- Versatile Communication Interfaces: Offers flexibility with RS485, configurable CAN bus, USB-C (virtual serial port), and PWM interfaces, ensuring easy integration into diverse systems.
- Advanced Control Modes: The D-FIN™ supports a variety of control modes, including hall-sensor trapezoidal, hall-sensor Field-Oriented Control (FOC), sensorless trapezoidal, sensorless FOC, and a self-calibration mode for precise motor operation.
The D-FIN complements Hydromea’s growing portfolio of cutting-edge solutions, including the EXRAY™ underwater inspection ROV, which utilizes the proprietary LUMA™ wireless communication technology.
