Hello good people. I have acquired a number of motor car cooling fan motors, the ones that are mounted behind the radiator. These are of unknown vintage but probably the least used of all the vehicles motors. They all work on 12 volts DC and take around 1 Amp no load, varying to 2 to 3.5 Amps with load applied (grip output shaft with gloved hand and squeeze hard). Unfortunately the case sizes vary somewhat, no two are the same.
My question is; has anyone used one of these type of motors in a model boat, can the speed be controlled by a electronic ESC? and how did it perform. From reading posts on the net, one of the problems I envisage is that of fitting suppression capacitors to the motors, also basic calculation: Volts * amps, 12*3.5= 42watts. Probably OK for a sedate speed but no use if you have a planing hull.
Thank you for taking the time to read this post.
