    Happy holidays to all.

    Question: I use an electric scooter throttle that utilizes the HALL EFFECT. I broke it and am looking for a website where one could find the replacement parts?

    As with most things electronic, there are several ways possible to do that. We would need more data about your throttle control.

    Farnell is the European equivalent of Newark in the US:

    Digikey is great when you just have a very small order, as they'll ship USPS 1st Class Mail (saves you money)

    Mouser is another supplier I like to use:

    Their search engine is among the most convenient. Besides, they're located in Mansfield, TX.

    You could try Electronics Parts Outlet. They're north of Westpark on Fondren. 3700 block, I believe.

    I will tell you what I know....hope this helps.

    The throttle is a three wire throttle: Red Green Yellow

    The three wires are attached to a three pin hall effect sensor. There is a magnet inside that passes over the sensor.

    The motor http://www.electricscooterparts.com/kollmorganinfo.html the throttle operates is a Kollmorgen MOT-K24300. It has an internal speed controller that provides the voltage req'd to power up the sensor. What that voltage is I DO NOT KNOW.

    Than you to all who have replied, your brain power is appreciated more than you know!

    There is a good chance you can canibalize the Hall effect sensor out of a computer fan motor. They hide in there.

    Here is your link, but corrected:
    http://www.electricscooterparts.com/kollmorganinfo.html
    You had the ")this" part too close in, and it became part of the URL.

    What we need is the part number from the Hall-effect sensor that got blown.
    In the meantime, from that link you provided, you can get the scooter running again temporarily by using a 5k pot. Your local Radio Shack might carry them.

    However, a plain pot won't have the safety feature of a spring return like a throttle would. It will also have a very limited lifespan compared to the Hall-effect sensor.

    I understand that a loss of mobility is a large inconvenience at best. However, I urge you to order the correct part ASAP, so that you can regain mobility with minimal risks involved. You really need some kind of automatic shut-off on the speed control so that it'll shut off if you let go of it.

    ALL motorized vehicles have this feature, not just mobility devices. Motorcycles, cars, boat motors, tanks, Jeeps - about the only exceptions I can think of offhand is aircraft, rockets and missiles. But none of those are in touch with the ground, either.
