Does anyone have any examples of converting turbines into motors? How has that worked out?

Is variable frequency or hydraulic coupling used for the speed regulator? How is it performing?
I haven’t heard of any cases related to this.
I haven’t heard of it either. The motor consumes a lot of power; it’s not as economical as steam.
This question should be asked in the [Production/Electrical] section; we have cases here of motors being replaced with turbines
If switching to motor drive, I think the speed control device should be selected based on specific circumstances: variable frequency drives are used for low power levels, while hydraulic couplings are used for higher power levels. The material flow rate does not change much; if the flow rate is high, a bypass line should be used.
It depends on the speed of their driving motors; generally, turbine speeds are very high, ranging from 9,000 to 12,000 revolutions per minute. In such cases, a gearbox is needed for the motor, with power being transmitted through a hydraulic coupling.
