RPM whith D6374 Odrive

Hello I would like to have some help.
I have 1 odrive 56v and 1 motor D6374 150KV with a CUI AMT-102 encoder all powered by a 18v 5Ah battery.

I need my motor to be at 5760RPM at the input of my planetary gearbox.

The calibration works well, but during my tests I can’t reach the I can’t get 5760RPM.
despite the modification of my parameters, I only get 2460 RPM.

odrv0.axis0.controller.config.vel_limit = 500
odrv0.axis0.controller.input_pos = 300

unfortunately when I enter odrv0.axis0.controller.config.vel_limit = 1000
I have the impression that Odrive is failing and the calibration no longer works.
I am forced to restore the Odrive factory settings.
Could you help me

18V * 150Kv = 2700 RPM

It is physically impossible to hit 5760 rpm at 18 volts with this motor. With ODrive, you will need about 55V to hit that speed, which is a fully charged 13s lipo.

Thank you for your response,

So I will need 55volt batteries, but how many Ampere will I need to get close to 5760 rpm?

With no load? Theoretically zero.
