Re: [ElectricMotorcycles] Controller for Steve?

[Andrew Wowk]

I second what Shawn said. My chinese controller on a chinese ebay scooter I bought was cutting back and getting real hot. I don't know how the rest of these chinese controllers handle continuous duty. Mine had the mosfets mounted on the side wall which was pretty thin and not carrying the heat well to the bottom where I had it mounted to the scooter frame. It was fine for short rides, but couldn't handle long rides. However, it was probably similar to the 350 watt rated controller at electricscooterparts.com , that they paired with the 900 watt motor for my scooter.

I use the Navitas TSP100-36 now and it works fine for my 36v 900 watt motor. I don't pull full power out of it continuously as this would dump the batteries in about 9 minutes, I get about 30 minutes out of my scooter. This controller has a large heat sink (compared to the chinese controllers that don't have one at all), and has not thermally cut back on me yet.

Shawn,
How is the ramp rate on these controllers generally? I was wondiering if there is a way I can adjust it on mine to hit the motor with full current right away?

Best regards,
Andrew

If a 100A controller will work for the motor (and at 1HP, it should be fine)
you could try this one:

We have used them on lots of scooter/minibike projects with that size motor.

Thanks,

Oops- I didn't scroll down far enough down the page of the link you sent
-now I see the 36V controllers. Yeah, looks like the one you mention may
work. Cheap enough to give it a shot. Thanks!

Once I get some experience with this, I'll be confident enough to start
a real conversion. I have a 6 mile commute, so I ought to be able to
build something with decent performance.
