Not really done for outright efficency. This arrangement lets the prime mover run at its optimum RPM, and the drive motors produce at a much lower RPM without the use of a reduction gear box. But there are lots of energy losses. Mechanical and thermal.

But there are lots of energy losses. Mechanical and thermal. Modern VFD 's help with efficency to a significant degree, but this type of drive was developed long before VFD's were available
