Issue in BLDC motor

Hello All,

Again, I need one more help on the sensored BLDC motor.

I am developing a driver which is having max current protection 20A. The motor is driven on 12V and 24V.

The motor is 3 phase BLDC motor.

My driver gives motor speed as 1800 RPM at 24V ,1.3A without load and 900 RPM at 12V,0.9A without load.

I have checked other 2 and 3 drivers which has dedicated IC in the circuitry for BLDC motors. They are giving following speeds,

2000 RPM at 24V , 1.5A current
1100 RPM at 12V, 1.1A...
