2.3.1.2 - Example of component selection
The component selection tables for 6-PULSE variable speed drives are detailed in paragraphs
2.2.1.3
to
2.2.1.6
, depending on the
power supply voltage used.
To assist the user in selecting variable speed drive components, an example application is described below.
Application:
• 132 kW asynchronous motor, 4 standard poles, 400 V power supply
• Centrifugal application (reduced overload)
• Altitude <1000 m, T_rate design temperature less than 40°C
• 3 kHz chopping frequency (no over-torque at start-up)
In the first part of the selection table 6-pulse 400 V variable speed drive of
, the selection indicated in yellow below is
obtained:
The selected LS model is 150T. “LS MODEL”
The second part of the table shows the selection of components for the Powerdrive MD Smart 150T variable speed drive, shown in
yellow below:
Model
LS 150T
therefore requires the choice of the following components:
• UPS: MD3INVxx260N (xx = AF because we choose a ventilated version), so the reference becomes
MD3INVAF260N
• Control module:
KIKITCxxREC
(xxxx = cable length)
• Rectifier: MD3REC1xx475N (xx = AF because we choose a ventilated version), so the reference becomes
MD3REC1AF475N
