Best way to control 150A Dc motor with Arduino

-

hi all,

i find out how safely control 2 1000w dc brushed motors arduino.
in particular, dc motors rated 1000w, 50a, 24v, 2400 rpm.
under load, in situations, can draw 150a few seconds.

i have radio transmitter system has receiver able provide 2 outputs:

- pwm in current mode (12v, 2a max)
or
- pwm in voltage mode (0-5v, 200 ma)

on receiver, have 2 outputs (one each stick on trasmitter).

i thinking use pwm in voltage mode input 2 analog arduino inputs , map them on 2 pwm arduino outputs.

the problem is: what best solution control high current? how control each motor in both directions?
i set maximum current limit (for example, 130a) safety reason.

should use 150a contactor, example?

thank suggestions!

how 150a contactor switch @ pwm rates?

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
