High School Student Looking for Help w/ Solar Car Project

[Bowman]

Me and my team were interested in purchasing the following motor kit: (https://www.electricmotorsport.com/...rottle-contactor-wire-kit-and-fuse-block.html). We were hoping to simply attach a centrifugal clutch to the shaft of the motor, but saw that the shaft on this motor had a diameter of 7/8 inches and that there are no 7/8 in centrifugal clutches on the market. Would anyone by chance be able to point me in the right direction as to what to attach to the motor's shaft? I would really appreciate any help or advice as I am very new to building vehicles from scratch. Thanks. - Alex

Hello and welcome...
Save your money.. you will not need that cent clutch... its electric...
Just sprocket to sprocket.... good to go...

Would this work for you? https://www.bmikarts.com/Pulley-Clutch-with-78-Bore-from-Hilliard-Extreme-Duty_p_3146.html

With an electric motor, no clutch is needed

a 20kW peak motor able to draw up to 400 Amps...
on a SOLAR kart?

where's the point in that?

the panel wouldn't even deliver enough juice to power that motor for more than a few seconds
if left out for a day... the weight alone increases batterylife by the same seconds roughly.

I don't see why you want a high power motor on a solar panel really.

Anywhoo:
as being said: no clutch of course!!

How many watts do you anticipate from the panel? It would take a pretty large one to deliver even 100W, which is 0.9% of that motor's capacity.

Do you plan to charge an onboard battery while also moving the kart, charging only while stopped, or just running off available panel power?

I think a smaller DC brushless setup might be better suited to the application.
