DC Motors – Mobile Marine

[shipwrightParticipant @shipwright]

Has anyone got the basic data on the T12 and T24 motors that are sold by Mobile Marine ? By basic data I mean No Load rpm, No Load current, Stall current – all parameters measured with nominal voltage applied to the motor terminals. I am assuming that the "12" and "24" in the motor titles refer to the nominal design voltage. Also the weight of these motors.

Parameters for T12 & T24 ?

Have you asked Mobile Marine Models? If they cannot or won't supply that data, then I would suggest you don't buy them, since that sort of information is essential to make the correct choice for your model.

Paul,

Thank you for responding. No I haven't contacted Mobile Marine – I thought I would try on this website first. I'm not in the market for motors at present but I use Mark Beard's Excel application and have expanded upon the list of motors for which he obtained the data (now got 87 on the "Motors" worksheet – though many of these may not be readily available or are too expensive for model boat constructors – Mark had 28 motors on his Worksheet). All of the motors are of the "brushed" type though there is no reason for excluding "brushless". For those wanting a relatively low operating rpm (say 2,000 rpm) and large torque (say 150 mNm) the choice is fairly limited particularly if you don't want a 1 kilogram motor of 70mm diameter ! Obviously you can match propeller to motor with a gearbox but that tends to be noisy and inefficient.
