Desktop size steel welded router 3 axis

Still not happy with the speed of X axis. Motor had to be slow down to 1450mm/min.
Z and Y goes above 2000mm/min.
Today I run only ballscrew nut with everything loose and still stalling.
I remember noticed that on dry test (driver - motor) one was stalling at much lower speed.
My motor is 23HS8630B with 1.6mH phase inductance, powered by 24V only, 6 cables (4 used only +A-A+B-B)
I use 4 wires so winding are in series 0 is not in use


I will keep it connected that way do not want to sacrifice torque at low speed, so need more voltage.
Am I correct?
