System Approach

Permanent magnet motors offer very high power density for minimum size simplifying integration. The high efficiency of these motors also maximizes the overall system efficiency. Offered in air-cooled or liquid-cooled versions, these machines offer the latest technology in high strength rare earth materials for very high power density (minimum size) and very high efficiency.

Calnetix applies this configuration from low to high speed applications, making it well suited for a wide range of applications. Designs that operate over 450,000 rpm are achievable, with 30,000 to 100,000 rpm being the typical operating range for Calnetix machines.

The robust rotor construction maximizes rotor stiffness for higher bending mode frequencies. The low number of rotor poles reduces stator losses by lower drive frequency requirements. The latest technology in stator lamination materials minimizes stator iron losses.
