2.2 Motor Resistance
For a wye-connected motor, the motor phase resistance refers to the resistance from the phase output to
the center tap (RPH_CT). This resistance is labeled as RPH_CT in Figure 2.

Figure 2. Wye-Connected Motor Resistance
For a delta-connected motor, the motor phase resistance refers to the equivalent phase to center tap in
the wye configuration. In Figure 3, this resistance is calculated as RY × RPH_CT = RY.
For both the delta-connected motor and the wye-connected motor, the easy way to get the equivalent
RPH_CT is to measure the resistance between two phase terminals (RPH_PH) and then divide this value by
two: RPH_CT = ½ RPH_PH.
请问其中delta-connected 的 RY × RPH_CT = RY.这电阻值RY怎么算？用多少来计算，是否有问题？
