    Default Littlescreamers new Water jacketed Outrunners

    Steven had asked me to post a little something about our new water jacketed outrunners we are producing. This is a project I have been working on for some time now and am very excited to be able to show off what we have coming out soon. I am posting some pictures as it is way simpler to show you how it work then to explain it.

    I will give it a shot!

    The internal cooling works by passing cold water through a bell attached at the end of the motor, This bell is removable and is sealed with 2 O-rings one front and one rear. this bell is completely enclosed and sealed, No water can enter the motor or the shaft as the bearing on the end is outside the bell and sealed with the O-ring. (see pic) Inside this bell is an extension of the bearing tube witch also holds the stator, Now on this extension I have machined cooling fins to absorb the heat with the water passing over these colling fins and the whole things is Aluminum so it wil act like a heat sink. So with this setup there will be no issues with heat and as all of it will be pulled strait from the motor and out the exit! The faster you go the better the cooling.

    As of now we are going to relese 3 versions of this design

    1 for the Mini boats

    1 for the mid size boats

    And a competition 1/8th 1/0th scale motor

    Yes, I'm awaiting test motors. Once the mid and large test motors are built I will give them a try.

    What will be the advantage of this outrunner against the NEU motors for example? Let's say i want to buy a NEU 1521/1Y (1577 kv), why shall I go for the outrunner? I believe price, torque but I am really interested to hear your opinion.
    Congratulations on your patent!!!
