Interpreting BLDC motor spec sheet

  1. Apr 28, 2012 #1
    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!
