One of the newest highlights at the Bosch Rexroth booth at IFPE 2023 this month was its newest Hägglunds Quantum hydraulic motor range. The range does away with established barriers, combining torque and speed with previously unthinkable efficiency. For direct drives in heavy-duty applications, it creates a powerful new reality.
The Hägglunds Quantum offers a top speed of over 150 rpm, yet it provides a sustainable maximum torque of more than 350 kNm. At corner power, where the two extremes meet, users can achieve a massive 3 MW – without sacrificing compactness or efficiency.
The massive wattage comes in the form of a massive motor — because the actual Quantum weighs about 400 kilos, the model on display was a 3D-printed shell without all the inner parts.
“The Hägglunds Quantum range rewrites the rules of power density, especially when it comes to efficiency at higher speeds,” said Wolfram Ulrich, Vice President of Sales, Hägglunds. “By stretching the limits so far beyond previous solutions, it introduces possibilities for greener operation, mobile applications and more.”
One range with two powerful aspects
Within the Hägglunds Quantum range are two motors with shared DNA. Hägglunds Quantum is the new name for the Hägglunds CB, which has evolved so significantly over time that it can no longer be considered the same motor. Tweaks in design and materials have increased its efficiency and tripled its life expectancy, making it the ideal basis for a bold new step.
Adding more power to the Quantum is done via the four connection ports, allowing the motor to simply be made longer with additional cam rings and pistons, Urban Strömberg, Manager, Mining & Materials Handling Industry for Hägglunds.
“Having very standardized parts, our delivery time is 6-8 weeks from order to shipment,” Strömberg noted during a booth tour. “We have few internal components that are standardized, so we use the same pistons, rotors and just pick and choose.”
This allows Hägglunds to increase efficiency by increasing flow with more connections, he said.
Key industries targeted with the Quantum range include surface miners, belt conveyors, and directional drills in mining, and mixers used in the chemical industry.
That step is the Hägglunds Quantum Power, which merges a slim new connection block with this reliable foundation. Through additional ports and innovative internal design, the block enables far higher speeds while retaining full torque capacity at high efficiency. Consequently, the Hägglunds Quantum Power can deliver high power with greater economy and sustainability than any previous solution.
“The two parts of the Hägglunds Quantum range, Hägglunds Quantum and Hägglunds Quantum Power, create a seamless curve without gaps in speed or torque,” said Ulrich. “One part reflects the constant, long-term improvement that we pursue in all Hägglunds solutions. The other is a result of radical new thinking – a true quantum leap.”
