an esc for DC motors 'brusched esc' in theory should emit an output signal composed of a wave, more or less square, at a fixed frequency with modulation of the duty cycle proportional to the ppm in output from the channel of the RC receiver. I say in theory because in some ESCs, in the outputs towards the moTors there are filtering capacitors and also recirculating diodes inside the Mosfets themselves that could alter the pure signal, so in the end, instead of many square waves, a single modulated wave would be obtained. only on the wave crests, therefore an almost continuous signal and therefore fixed or slightly variable speed on the motors. the best and rather easy solution to implement is to use a microcontroller like Arduino which also has libraries ready for the BTS7960 modules, to convert the ppm RC receiver signal into PWM and DIR + Enable to better control the power module and take advantage of the variable speed

I think it is using an besc for DC motors 'brushed esc' costing a few dollars on aliexpress, the output of the BESC instead of directly driving a small motor drives the inputs of the bts7960, obviously it feeds the BESC with no more than 5 volts for not damage the inputs of the bts7960. in principle it works fine as a system but it would be better to use a microcontroller like arduino to create the interface :)

@@salvatorebarbaro5862 how can I operate 48V 1200watt motor wirelessly , plz guide.

@@pushpakdeshmukh9106 you intend brushed motor or brushless ? 48V - 1200W are 25 Amp, for brushed motors : some H Bridges can handle 25 Amp 50 volts, a lot depends on whether you then have to control them via an RC remote control, in this case there are 2 alternatives, an H bridge that accepts the PPM signal of an RC receiver as input, or an arduino that converts the PPM signal of the receiver into PWM signal to drive the H Bridge . A little more difficult to manage a controller for Brushless motors at 48V , which hardly have an input for PPM RC signals, often only have a 0-5V input which comes from the throttle knob. in that case, always with an arduino-type microcontroller, the PPM signal must be converted into a 0-5 Volt signal and applied to the input of the BR controller instead of the knob

ESC for pwm signal.
