Brushed vs brushless speed

[mdan]

I recently upgraded to a brushless 1500 watt superkids motor, running a 36 volts at 20 lipo4 fox power, using a lyens 4100 controller. Single reduction at 14/110 using 24 inch wheels etc.
Coming off a brushed 1000 watt currie motor with a 36 volt 25 amp chinese controller, everything else the same, batteries, reduction etc.
I realized that the brushed motor had way more torque, faster wot etc. etc. but my brushless is slower but runs alot cooler etc. etc. by slower, I mean torque and top end. Dont get me wrong, its still fast, but not as fast as my brushed motor? Now at 48 volts, it scoots, but does run warmer etc. etc.
Should I just buy another 12 /20 lipo4 fox battery and run it at 48 volts, Edward Lyens says the controller can handle 48 volts fine, but I would have to get another charger etc. etc. Can the brushed motors be fixed to run at the higher volts, when I took off the rear housing of the currie, the spring contracts and wiring were burnt and chard pretty good!!

Anyone else with the currie motor running higher watts, thats lasted say, 1000miles? I miss the torque of this motor, who can rebuild it?

thanks,
Mike

You might be able to get the torque you're after by allowing more amps from your controller. If your Lyen controller (and battery) can handle putting out more amps it should just be a matter of re-programming its amp limit? Torque = Amp draw.

Are the amps equal?

Because since a brushless motor is more efficient, it uses more of the energy you give it. I think you are giving it less amps than you did the brushed.

I would guess the same thing...^^
