The N-compact high-speed motors from Siemens A&D offer greater efficiency and are compact and require little maintenance. The series covers the voltage classes from 400 through 690 V and is available with outputs between 200 kW and 1050 kW.  Thanks to forced ventilation and special rotor design, the motor is suitable for the speed range up to 5000 rpm. The intelligent use of oscillation elements with excellent damping properties mechanically isolates the machine from the actual baseplate. This means that, despite the high motor speed, no additional structural provisions are necessary. Especially when combined with the Sinamics G130 and G150 frequency inverters that are particularly suitable for turbo machines, the high-speed motor forms a coordinated drive system.
