Title: surveillance hovercraft Post by: saurabhreigns on April 01, 2012, 10:04:42 PM I am working up to make an RC hovercraft which will be using a BLDC motor for lift system,
a brushed DC motor for propulsion system a servo for rudder assembly.(plus a wireless camera mounted over it) I do not have a standard Tx Rx system(futaba or alike), so i have decided to develop a Tx Rx system which will be used to switch ON and OFF the lifting motor(BLDC motor) and wil be able to run the propulsion motor at low,med,high speeds and in reverse direction. Also ,it will be able to control the rudder servo. now where i am facing problem right now is the issue with BLDC motor. I want to know that can it be triggered using a 555 timer IC connected to the ESC which is further connected to the battery and BDLC motor. If this is possible then i would like to know HOW? A 555 ic alone can do this job ?or a microcontroller is a must? i have attached circuits and draft build PS.-bdlc-brushless dc motor esc-electronic speed controller |
