stuck on my build need help with BLDC setup 10kw on my buggy urgent!
Ive been building an Electric buggy for myself to daily drive. most of it is complete, charging system works lovely. sound system, lights, everything is fine. However I am and have been stuck on the drive train. I have 35 inch tires. attached to a drive train that is realistically around 2:1 . the whole machine weighs about 900 pounds? I started with a 5kw BLDC motor. it didnt really do the trick. SO i upgraded to a 48v 10kw GM BLDC with a VEC500 controller and now we are moving at least. we got up to 30-40 mph. however acceleration is absolute dog crap i mean from a dead stop she struggles. also it seems the battery never gets taxed for the full 10kw. at peak amperage draw i saw maybe 160, when she should be able to do 200a draw. the controller is rated for 10kw continuous as well as 20kw peak for short bursts, i am no where near that, and with my gearing i should be able to get 60 mph . so what gives? why cant i squeeze all the power from my equipment? also motor hardly gets even slightly warm. controller a bit but since i adjusted a few settings its much better. thoughts? i need to finish this project asap!
