Simon Chaddock Posted August 16, 2022 Share Posted August 16, 2022 Also don't forget the ESC is working hard too. A MOSFET (there are 6 in the ESC) generates a tiny bit of heat at each switch on/off but it is doing so up to a thousand times a second! Like all electronic components if it get too hot it fails. A situation made worse by the fact the actual electronic 'switch' is microscopic and is encapsulated in a block of plastic. There is an aluminium heat sink on the face of the MOSFETs to conduct this heat away but then the whole ESC itself is wrapped in a thick layer of shrink wrap. 😲 The temperature you feel on the outside of an ESC has little bearing on the peak temperature inside the MOSFET. With a typical ESC layout the amount of heat that can actually be dispersed to the outside air is limited. Fortunately most electric flight time is relatively short. As Piers suggested many consider a 30% 'headroom' in sizing an ESC is advisable both for its extra heat absorbing capacity and to cover variations in the manufacturing quality.
