Drives for a synchronous or asynchronous motor working as a spind-
le
The following graphs show the maximum rms current in continuous duty
cycle (that is, the rated one) depending on the switching frequency of the
power transistors that the drive modules for asynchronous motors can
supply in a temperature range between 5 °C (41 °F) and 60 °C (140 °F).
For a switching frequency fc = 4 kHz
F. H3/98
Current derating on “SCD 1.15” drives for fc = 4 kHz.
F. H3/99
Current derating on “SCD 1.25” drives for fc = 4 kHz.
F. H3/100
Current derating on “SCD 2.35” drives for fc = 4 kHz.
F. H3/101
Current derating on “SCD 2.50” drives for fc = 4 kHz.
