depends on the horse power of the motor as to the controller you would like to use   ,,, on my x3 mill I us a 2 hp  tread mill motor 

a good controller for tread mill motors ,  model no KBIC-240D (9464B)   INPUT 115/230 volts  or  VAC-50/60 hz ,,, output   0 - 90/180 vdc  ,,, rated  6.0  amps  dc current  ,,, using an added heatsink the rating goes up   to   12.0 amps direct current    you will find them on    flea-bay  address  KB ELECTRONICS. INC.  CORAL SPRINGES,  FL 33065  I picked 2 of these up on e-bay  for about 60 dollars  some years ago    you may not find the exact model  ,,, any of the kibic controllers  will do   the plus side  they ar made in the states  ,,,  they are a nice small board   4/1/4  wide 3.3/4 depth front to back   and aprox 2" deep and that's allowing for the wires standing up (connecting wires)   ,,,just be carful the amps you draw though it   ,,,  this particular model  I can run a three hp dc motor with an added heat sink   .  there again some one els might recommend a different controller , they are much as muchness
