Danfoss Power Solutions has introduced the Thorx CLM 5 C cam lobe motor which is designed for use with drum drives on road rollers and other compaction equipment. This hydraulic motor is the latest addition to the company's Thorx family of cam lobe motors, first introduced to the mobile equipment market in 2023.

Features of the Thorx CLM 5 C cam lobe motor include:

  • maximum displacement of 545 cc suits use on compaction machinery up to 3.5 tons
  • integrated parking brake at center of the motor for a compact design
  • multi-disc brake eliminates the risk of jamming associated with dog clutch brakes utilized in other cam lobe motors
  • total efficiency of 92% reduces heat generation, extending the service life of components such as seals and bearings
  • two strong taper roller bearings to prevent shaft deflection and thereby eliminate hydraulic oil leakage at the shaft seal
  • bearing arrangement withstands higher loads than cam lobe motors with ball bearings, providing a longer service life
  • balanced rotary group offers smoother low-speed rotation, enabling machine owners to achieve better road finishing and a smoother road surface 
  • 12 pistons and nine lobes enable rotary group to keep a constant number of pistons under pressure, reducing low-speed ripple
  • interchangeable with other drum drive cam lobe motors for ease of integration.
