Danfoss Power Solutions, a leading global supplier of mobile and industrial hydraulics as well as electric powertrain systems, today announced the launch of its Thorx family of cam lobe motors. The first product, the CLM 8 S motor, is now available. 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.

  • With integral parking brake, Thorx motor is 33% shorter in length than other cam lobe motors, reducing space requirements
  • Motor reduces shock at speed changeover by 70%, improving machine handling and operator comfort
  • Optimized brake technology lasts 20 to 25 times longer than competitive motors, extending motor service life

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 superior machine handling and better operator comfort. The motor also produces less noise when shifting, further improving comfort. 

“We developed our Thorx cam lobe motors in close collaboration with our customers,” said Chris Shrive, head of Cam Lobe Motors, Danfoss Power Solutions. “The first thing they told us to do was reduce shock at speed changeover. We didn’t just meet their expectations; we set a new standard for smooth, predictable, fast changeover, regardless of oil temperature.”

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 33% shorter in length than similar products, creating the most compact drive solution in its class. The smaller size results in easier integration and assembly while enabling the use of larger, longer-lasting chains.

The integral parking brake is the toughest on the market, offering a longer service life. Thorx motors utilize a proven brake design that has been optimized to withstand 100 dynamic emergency stops throughout a machine’s lifetime, which is 20 to 25 times more than competitive cam lobe motors.

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, plus improved mechanical efficiency at high speed. Operators can achieve faster travel speeds or use less power at the same speed while wasting less energy in the form of excess heat.

“Danfoss Thorx motors have reinvented cam lobe technology,” Shrive continued. “This is the most efficient, most power dense two-speed technology on the market. Our CLM 8 S motor for skid steer loaders is just the beginning.”

Ultra-fast charging for an ultra-fast car

A team of students from Eindhoven University of Technology has succeeded in developing an all-electric, ultra-fast charging prototype race car. Set to roar into action at the Le Mans 24-hour endurance racing event in France, the team leveraged the advantages of Danfoss technology to solve its fluid conveyance challenges.

All-electric racing cars are not new, but how does the endurance motorsport segment join the green revolution, where events require the rapid recharging of race cars? Enter InMotion, a student team from Eindhoven University of Technology in the Netherlands which set out to develop an all-electric race car with ultra-fast charging capabilities.

Electric refueling

To help take InMotion’s fast charging technology (called electric refueling) from concept to reality, the team reached out for technology sponsors. PowerFlex, an expert supplier of hose solutions based in Weesp, Netherlands, stepped up to the challenge. The company is a long-term Danfoss Power Solutions distribution partner.

“We saw huge potential in their ambitious project,” said Ruggero Grillo, marketeer at PowerFlex. “We believed in their goal, their underlying technology and their passion, so we were proud to support them and help accelerate the motorsport sector’s transition to a green energy future.”

The PowerFlex team was tasked with helping InMotion identify the optimal fluid conveyance solutions to meet several of The Revolution race car’s key challenges. These included minimizing heat buildup in the 58 kilowatt-hour battery pack during fast charging, enabling quick battery disconnection, and delivering efficient cooling.

Battery pack cooling

To maintain the optimal battery pack temperature during fast charging, PowerFlex recommended the Danfoss Evercool GH001 multi-refrigerant hose and fittings due to advantages that include near-zero permeation, tight bend radius, wide temperature range, and compatibility with many refrigerants.

In addition, the Danfoss EZ Clip system for hose assemblies gave the InMotion team flexible installation options without the need to invest in costly crimp tooling, while Danfoss Hansen aluminum dry-break ADB couplings were chosen for quick and easy battery connection and disconnection without fluid loss or air infiltration.

Finally, to optimize heat distribution from the race car’s battery pack, PowerFlex provided various Aeroquip by Danfoss Performance Products, including hoses, fittings, and adapters. Throughout the project, the knowledge and experience of PowerFlex was a crucial asset in The Revolution race car’s successful development, providing InMotion with on- and off-site technical guidance, testing, servicing, and more.

“Offering a low weight-to-power ratio, high performance, and racing-level quality, the Danfoss components we chose were designed for exactly this kind of challenge — and they delivered,” stated Grillo.

12-minute charge

InMotion’s prototype race car is now able to reach an 80% state of charge from near depletion in just 12 minutes. The installed solutions keep the vehicle as lightweight as possible, while also making it easier for InMotion to assemble or reconfigure systems. Importantly, The Revolution endurance race car remains on course to showcase the game-changing potential of fast charging at the world-famous Le Mans.
