    How to choose a speed controller Empty How to choose a speed controller

    Post  Manuel Garcia on Sat Jul 25, 2015 9:47 pm

    I am new to rc submarines and I am building a typhoon class Russian submarine from scratch. I have two dc motors from a printer and I don't know what speed controller should I use. Each one consumes 700 ma ( with no charge) and 2,5 amp under pressure. I am going to use a 11,1 V lithium battery, so should I use a foward-reverse 6 amp speed controller? And where can I get one ? Thank you

    Hi Manuel,

    The 2.5 amp (stall?) current is a good guide for selection but multiply it by a few times. (Hold the shaft and measure the maximum current.)

    So 10 amp ESCs or so would be OK.

    And yes, one per motor.) and a channel each will give you the most control. (You may be able to do static turns but this can be hard with subs - props too close together.)

    Microgyro and Mtronik are both good suppliers which I have used.

    David

    (Try searching using the term ESC on this forum for more info.)

    Thanks for your answer, David ;
    And yes, 2.5 amp was measured in stall.
    I have purchased a viper marine micro 10 from mtronics and I thought that the easiest way to turn was with a ruder, using the same speed controller for the two motors, putting a fuse for more safety, as I saw in other models.
