Electric Go Kart - 72600 + DLC-28 72v 40ah Batttery

[Shenta]

Hello All,

Would like to share my latest project, electric kart with DLC-28 and my 72600 controller, packed with 22s 40ah MNC batteries.
The goal was for 60hp, utilize every last drop of what DLC-28 could offer, but as I took the motor apart, it is somewhat disappointing, the wires they use for motor winding is not rated up to their spec. sheet, so I try to keep the phase amp down to keep the motor cool.

Anyway, enjoy the video:

Excellent result there, despite your motor worries.
How do your lap times compare to somethig like a Rotax Max ?....it seems to perform very similar.

Hi Shenta,

Looks like great fun. Love the data overlay on the video too.

Motor seems pretty cool at 80 most of the time considering how hard it's working. I'm sure you'll be lifting those phase amps soon......

Hello Hillhater, glad that u r in kart sport also, the Rotax Max engine is certainly one of the very best out there, but as all gas engines suffered from low torque at low rpm, the acceleration of electric is definitely better. I can get 120Nm of motor shaft torque from 0~1000rpm, which does not computer for the gas engine at all. As the speed picks up, the gasoline engine does benefit from lighter weight for the overall system (24Kg of motor and controller + 24Kg of battery vs 18Kg Gas Engine), so on the track with alot of corners, electric still wins.

Hey Gregory,

Thanks for the encouragement, I am planing to design and make my own axial flux motor soon, base on this experience, I am hoping my new motor will be able to take the full advantage of my controller.

Cheers
