At the equivalent rated speed, LSRPM motors in the DYNEO® range have significantly better efficiency than high-efficiency induction motors. 
This difference in efficiency becomes even more significant when operating below this rated speed, which is by definition the case in variable speed applications!

The LSRPM motor is designed to rotate faster than an induction motor. This allows the motor speed to be adapted to that of the driven machine, eliminating transmission devices such as gearboxes and enhances performance of the driven machine, by increasing its speed.
As a consequence, the machine overall efficiency is highly increased.

The return on investment time compared to a conventional solution is very often less than 12 months.
