7.3.13.2 Motor Inductance

For a wye-connected motor, the motor phase inductance refers to the inductance from the phase output to the center tap, LPH (denoted as LPH in Table 7-4). For a delta-connected motor, the motor phase inductance refers to the equivalent phase to center tap in the wye configuration in Table 7-4.

MCF8329HS-Q1 Motor InductanceFigure 7-36 Motor Inductance

For both the delta-connected motor and the wye-connected motor, the easy way to get the equivalent LPH is to measure the inductance between two phase terminals (LPH_PH), and then divide this value by two, LPH = ½ LPH_PH. In wye-connected motor, if user has access to center tap (CT), LPH can also be measured between center tap (CT) and phase terminal.

Configure the motor inductance (LPH) to a nearest value from Table 7-4.
