High power density, high efficiency

Built on extensive rotating machines experience

Build based on 100+ years of experience and know-how we continue to deliver innovative electrical and mechanical power solutions to the world. Our machines efficiently operate in challenging applications and severe environments where reliability and ease of maintenance is critical. A specially designed frame and stator in the C7 that cools so effectively, that higher power ratings are easily achieved by smaller frame sizes.

Fast builds with pre-engineered components

The C7 features a standard set of frame, rotor and stator components that can fit into the majority of common application configurations. This means a faster cycle time to build and more consistent performance results during operation

Construction features

Standard-built C7 squirrel-cage induction motors operate at 50/60 Hz, with outputs ranging up to 6,000 kW (9,000 HP).

  • Designed for direct-on-line or VFD applications
  • Rated Ex for use in a hazardous location
  • Welded totally enclosed frame construction with air, water and blower-mounted cooling - WPII enclosure also available
  • IP 55 standard protection for TEAAC (CACA) or TEWAC (CACW)
  • IP24 standard protection for WPII enclosures

Benefits

  • Small footprint due to high power density
  • High efficiency to assist with energy savings
  • Low vibration enables high reliability and MTBF
  • Low noise level to reduce environmental impact

Available configurations

  • Available for the various applications: pumps, compressors, fans, refiners, etc.
  • Various standards (e.g., IEC, NEMA)
  • For the most rigorous specifications (e.g. API 541)
