Notes:
-
AC Motor Choke inductance values calculated @400 V, 50 Hz / 480 V, 60 Hz
-
AC Motor Choke impedance is nominally 2 % of drive rating
-
AC Motor Choke maximum voltage rating should be 480 V +10 %, TN/IT
-
AC Motor Choke frequency of operation is 0
– 120 Hz
-
AC Motor Choke inductance at peak current should be >85 % of its nominal value
Calculation
The choke ratings listed above are for guidance only. Customers may want to calculate their own ratings
using the formula below:
𝐿 =
(
𝑉𝑜𝑢𝑡
√3
×
𝑍
100
)
𝐼𝑜𝑢𝑡
÷ (2𝜋 × 𝑓𝑜𝑢𝑡)
Where:
L
= Inductance/phase (H)
Vout
= Line-to-Line Output Voltage (V)
Z
= AC Motor Choke Impedance (%)
Iout
= Rated Output Current (A)
fout
= Output frequency (Hz)
