Help needed for VESC set up!

Hi. I would need some help as I’m not familiar with this area. I don’t know much about this area but I need to set up my system so I can use it for a project. So I have a motor with the following known specs: BLDC max power 1100 W, a 36 V (2 x 18v) Makita BL185B battery pack (each battery is 5 Ah 90Wh Li-Ion). The system is Radio controlled by a Radiolink RC3S rc. I need the set up of the Vesc to give maximum torque and maximum speed. The system need to travel as fast as possible on a closed circuit oval rail with a load of about 15 kg. I need it to brake and reverse, also regenerate current. I have no other info about the motor or the batteries. The system will not be used more than 1-3 minutes at a time.... but autonomy is important. Manny thanks!

We really need more information about the motor to be able to help you. What is the rated speed of the motor? And at which voltage (or equivalently, what's the motor's Kv (rpm/V))?

Because to get maximum power out of the system you need to run the motor at its rated speed.

If you really don't know anything else about the motor, then take a picture and maybe we can make an educated guess about rated rpm. You will still need to measure Kv - for example by running the motor without load to some rpm and checking the duty cycle. Or by using an oscilloscope, if you have access to one?

I’m sorry but the maker of the motor does not give any details. Could I use the vesc tool to read the specs?

Yes, you can try to run the motor under computer control and see how fast it goes on say 18 or 36V of battery.
