This system modulate through pulse width modulating way realize speed of transfering of motor mainly, including remote control and manual some. The ones that have also realized the arrival of the motor , changed direction , applied the brake are controlled remotely in addition, square wave used rapidly to adjust adopt form by 555 timers take hole in harmony oscillator produce more than a variable one, and make for circuit , remote control of part, convenient realization many distance control, adopt four passways of wireless remotecontrol devices, spend arrive code and decoder among device this. Is it choose passway to realize through code decipher , control corresponding circuit power put through and disconnected, some extensive applying to the relay and contactor to the start and applying the brake of the motor. Whether through every comprehensive application of part , realize single ring transfer 1 speed ratio. 100, remote control is before greater than 10ming.
