Motors themselves are already very efficient, and only small gains can be made. However, if the entire system (electric motor system--EMS) is taken into account, 30% improvements are possible. The entire system includes the power conditioning (ASD), the motor, mechanical drive/coupling, and the process device (e.g., pump, impeller, fan, etc.). The problem is that these are never looked at as a system, but as separate components. (Even in large companies involved in more than one area, the motor people don't talk to the drive people don't talk to the device people).
