The window motor is a different (but very similar) motor.

Hi I am a member of team 4613 Barker Redbacks, we have designed a low cost, low part count gearbox which gives the motor a 7.5:1 gear reduction, with a ½ hex output shaft. Our team has the capacity to manufacture these gearboxes in-house and we have partnered with a local sponsor. We are going to donate 40 of these gearbox kits to rookie teams in countries where it can be difficult to get parts like Australia, Brazil, Turkey and China among others. We will also spread the project to the FRC community by encouraging teams who have access to similar machining resources and distribute the gearboxes to teams in their area.

We have been in contact with Frank and he has confirmed that the throttle motor will be legal and sent out in the KOP once again in 2016(but with the FirstChoice release, we already knew this)

We have already made several systems utilising the gearbox we have designed, including a Polycord intake.

More information about the project will soon be on our website: www.team4613.org

I want to see what you did with the throttle motor.
4613 you were a great alliance captain on Curie.
Thanks from team 4061.

I remember seeing them on 2512's robot in 2013. I think they used them on the fly wheels that kicked the Frisbee from their ground intake to their hopper.

This is pretty cool.

We had only thought of using them as speed encoders - similar to 1640. nice that free speed is about equal to a CIM.

If these work and it provides a use that teams can leverage, I am sure that all the throttle motors that anyone would want are available from the team community - for the cost of shipping. - nice re-use / recycle per the original intent I am sure.

Though it remains a low power motor and typically the transmissions are the cost driver not the motor....
(and 10X throttle motor power equals 1X AM-9015 motor power...)

Change is happening! - only throttle motors allowed! 30 throttle motor drivetrains!

The throttle motor gearbox has been designed to be simple to integrate into robot designs, the gearbox shaft smoothly slides through the 1/2 inch hex hole in the gear assembly. This enables teams to use any length gearbox shaft they like, without having to purchase expensive couplers. The gearbox will be sent out with bushings, and it will be simple for teams to replace these with 1/2 hex flanged bearings if they desire.

How are you dealing with the motor leads being inside the gearbox? I couldn't see any wires inside the gearbox to power the motor. Maybe I'm missing something.

Due to the gearbox design, there are many possibilities on how to power the motor. We have found spade connectors to be the most effective method of supplying power. These fit through the holes on the front of the gearbox, but the pins can also be bent at 90 degrees to supply power from the sides. Soldering wire directly onto the power pins works great too.

Ah. Now that you say that I see the little holes in the front of the gearbox. I wouldn't have thought they are big enough for spade connectors, but I guess looks can be deceiving.

Have you considered making a provision for mounting two valve motors in the gear box? 2015 rules allow driving two valve motors of one controller. No reason to think 2016 rules would be different
