DIY BLDC - power supply sizing?

I am currently in the process of building a sensor-less 3ph axial flux BLDC with concentrated windings. I’m thinking 12s10p but have not yet decided. It’s just for a project - not for real world applications. And by no means and I am expert in this subject. However I am trying to gauge what size power supply I will need to drive it. I know that the speed I want it to operate at will also impact this to some degree. However is their a rule of thumb which will help take this into consideration. If I know the parameters of 1/12 of the coils.

Below are the estimated results I get when using a solenoid calculator for one coil. (They are air coils)

Coil Parameters | Wire Diameter - .321 (mm) Number of Turns - 2000 (turns) Bobbin Length - 40 (mm) Bobbin Diameter - 31 (mm) Rated Current - 1amp (I) Gap Distance - 1 (mm) Results

Turns per Layer - 124 (Turns per Layer) Number of Layers - 16 (Layers) Coil Diameter - 40 (mm) Cross Section Area - 970 (mm²) Total Length of Wire - 220 (M) Total weight of wire - .159 ( Kg) Resistance/(M) - .213 (Ohm/M) Resistance - 47.063 (ohms) Inductance - 88549 (uH) Voltage at Rated Current - 47.063 (V) Power at Rated Current - 47.063 (W) Electromagnetic Force - 1776 (N) 399 (Lbs) Cross Section Area - 706 (mm²) (A)

• BLDC is an adjective, you are building a BLDC what? – user253751 Mar 15 at 17:59
• ”Power at Rated Current - 47.063 (W)” So at least 47 W + your drivers losses. – winny Mar 15 at 18:07
• If the coil resistance is 47R and the supply is 47V then the STALL current (per coil) is only 1A; the motor operating current will be MUCH smaller once you allow for the back EMF ... this will be a pretty low power motor. – user_1818839 Mar 15 at 21:16
