3.4.15 Motor Insulation

For motor cable lengths ≤ the maximum cable length, the motor insulation ratings listed in Table 3.12 are recommended.
The peak voltage can be twice the DC link voltage or 2.8 times AC line voltage, due to transmission line effects in the motor
cable. If a motor has lower insulation rating, use a dU/dt or sine-wave filter.
