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?
