What Kills a Brushless Motor – Current or Voltage
This may not be all that common, however, brushless motors can fail. There are many people out there that have seen this happen first hand. What makes them fail electrically really only comes down to two parameters. Voltage and Current. In this article we will break down each parameter. Does a Motor Fail Electrically due …
How RC Boats and EDF Jets can pull 120A+ reliably
RC boats and EDF jets come to mind when it comes to the top performance vehicles in RC and the most demanding on it’s components. Pulling 120A+ reliably is not as easy as plug and play. Especially if you are operating an RC that you had built. Even ready to run or fly RC’s have …
Does a Brushless Motor Pull Power from the ESC?
Understanding how power is created in an RC power system will allow you to build or operate a more reliable power system. Power is a difficult parameter for us to understand as we can not see it or hear it. The only way we can determine its presence is by measuring it. To answer our …
Parallel Charging for RC LiPo Battery Packs
With the high performance applications that we are all after today, power consumption is about as great as it’s ever been in RC. Whether you are piloting an EDF jet, driving an RC Car or racing an RC fast electric boat a 100 amp power draw is not uncommon. With this much power being drawn, …
Sensored vs Sensorless Brushless Motor Applications
How a Sensored vs Sensorless Brushless Motor Works A brushless motor receives power from the electronic speed control. (ESC) The speed control must know the position of the rotor in order to accelerate the motor from zero RPM smoothly. When it does not know the position of the rotor, the ESC must determine it. The …
