Hi everyone, first time poster!

Im having trouble reading the spec sheet attached and want to confirm the values Im using for calculation of Tm and Te.

The 3 phase wye BLDC motor spec sheet lists

1. Terminal Resistance = R2ph = 0.06 Ω

So this is Rphase and not R(line to line)?

ie Rphase is the resistance of each winding/phase of the 3 phase wye network?

2. What is the correct unit of inertia since it affects both the units of Kt and torque T?

Load inertia is listed in (kg cm^2) ie in SI (kg m^2)

(kg m s^2) {dividing "kg m^2" by gravity g } makes sense since

"torque due angular acceleration T = angular acc * inertia"

Thank you for taking your time to read this!
