1 RF based Wireless Speed Control of DC Motor Drive using MOSFET
In this project, i have a wireless control of speed of DC Motor. when a speed is set at a sending end it is transferred to a remote receiver section through RF Media And then it is converted into a command and sent to an Embedded PIC Microcontroller for controlling the speed of the DC Motor. The Drive uses the MOSFET to change the firing angle, so that we can vary the speed of the DC Motor. It has field and armature control. The RF Channel used is 433MHZ. The speed can be set by using a Keypad.
