In general, the Brushless DC motor speed controller uses an Atmega 16 microcontroller and a MOSFET, which often increases MOSFET's temperature, especially when is loaded. This article discusses use of IC NE555 CD4017 as frequency regulator to MOSFET gate by periodically igniting forward voltage from change in potentiometer value. We carried out test unloaded state with variations 2.5 Vac, 7.5 1...
