More information
An example of a highly efficient drive system with efficiency
class IES2 is the new synchronous inductance drive system with
SIMOTICS reluctance motors and SINAMICS drives.
More information is available on the Internet at
/drivesystem-reluctance

/simotics-sd
Power loss data of SINAMICS converters for single-axis drives
are available on the Internet at
