N-compact High-Speed

Simple, cost-effective, reliable

N-compact High-Speed is based on the N-compact series of motors and has a speed range that extends all the way up to 5000 rpm. Our experts didn‘t leave anything to chance in order to achieve this high speed: They developed a special rotor design and the motor is decoupled from the foundation using antivibration damping elements. And last but not least – all of the motor components were carefully selected to ensure that they can handle the high speeds.

The result is quite convincing: Using our innovative motor, not even high-speed machines – such as highpressure fans, screw compressors and special centrifugal pumps – require a gear unit. This means that the complete unit requires fewer drive components. This saves space and weight, further increases the reliability and efficiency and at the same time again reduces the amount of maintenance required.

N-compact High-Speed- Customer benefits

• Rugged, space-saving and efficient basic motor concept
• Sub-critical rotor design and forced ventilation allow the full speed control range to be used
• Can be used in direct drive systems
  - higher system efficiency – optimized to the operating range
  - increased level of security against failure
  - lower engineering, mounting and maintenance costs
  - lower space requirement
• Lower foundation costs by using anti-vibration elements with high damping characteristics
• The rotor can be balanced while still mounted in the motor
• Harmonized system together with SINAMICS drive converters
