CLM 8 S Cam Lobe Motor

Nov. 2, 2022
Danfoss Power Solutions' CLM 8 S Cam Lobe Motor integrates the parking brake rather than bolting it to the rear.

The first of the Thorx family of cam lobe motors is the CLM 8 S motor. Designed for construction machinery with chain drives, such as skid steer loaders, the compact motor offers better performance, higher efficiency, and longer lifetime than other cam lobe motors.


The Thorx motor features newly developed two-speed technology, which offers 70% shock reduction when shifting speeds compared to other cam lobe motors. The technology delivers smoother speed changeover with a consistent, quick response time, even at low temperatures, resulting in good machine handling and better operator comfort. The motor also produces less noise when shifting, further improving comfort. 


Compact construction is another considerable advantage of the Thorx CLM 8 S motor. By integrating the parking brake rather than bolting it to the rear, the motor is shorter in length than similar products. The smaller size results in easier integration and assembly while enabling the use of larger, longer-lasting chains.


Thorx motors utilize a proven brake design that has been optimized to withstand 100 dynamic emergency stops throughout a machine’s lifetime. The Thorx CLM 8 S motor offers 5% higher efficiency than other cam lobe motors, with better starting efficiency and performance at low rotations per minute and improved mechanical efficiency at high speed.

  • Performance: Achieve better performance at low RPM and improve your high-speed efficiency with THORX motors.
  • Efficient two-speed technology: THORX offer you efficient two-speed technology.
  • Leading on length: Improve robustness of chains and achieve easier integration and assembly of machine thanks to the compact size of THORX motors.
  • Smooth two-speed operation: Improve two-speed shifting thanks to the THORX design which delivers 70% shock reduction and a consistent and short response time - even at low temperature.
  • Integral multi-disc parking brake: THORX motors offer a strong parking brake. The brake is designed to withstand 100 dynamic emergency stops during machine lifetime.
  • Flexible program: THORX motors feature a wide range of mounting interfaces and shaft options to suit perfectly onto your machine.
