80AMPS All In One ESC for drones

/in /by

DRF is pleased to announce the release of the prototype design of our high current Brushless Motor Drive. Capable of delivering a peak current of 80 Amps, it offers a wide operating voltage range of 30 to 100 Volts, and it can safely operate at temperatures up to 50°C. The unit is designed for use as an Electronic Speed Control (ESC) for drones, as well as for battery-powered tools; such as drills, grinders, and cutters. 

 DRF’s proprietary all-in-one board includes: 

  • A micro controller 
  • A power stage 
  • A gate driver 
  • Temperature monitoring for the switching MOSFETs 
  • Protection against voltage transients 
  • A Controller Area Network (CAN Bus) 
  • Onboard protection against under-voltage, over-current, and over-temperature 

 Handling 80 Amps on a Single-Board Device: 

Designing an 80 Amp peak current with SMD switching devices was very challenging; particularly, because of the size and weight of the heat sinks normally required for cooling the switching of the MOSFETs. To achieve this goal, each of the PCB’s eight layers included two ounces of copper to spread the heat away from the MOSFET junction. Then, we added more than 500 ten mil (0.254 mm) thermal micro vias, in order to reduce thermal resistance of the system. In this manner, we caused the removal of excess heat from the die, through the PCB, to the ambient environment. 

Great for UAV’s! 

The 80 Amp peak current, and the superior efficiency that our Brushless Motor Drive provides, makes it possible for UAVs to stay in the air longer, in order to endure harsh headwinds, and all the while carry larger payloads.
