Bringing high torque and efficiency to industrial hydraulic applications
Danfoss Power Solutions has launched its Vickers by Danfoss ICMB Industrial Cam Lobe Motor, a radial-piston hydraulic motor that delivers ultra-high torque in a compact package. The motor has been designed for maximum efficiency, durability, and reliability, providing the necessary power and precision for demanding industrial machinery and pulp and paper, primary metals, mining, marine, and forestry applications
Engineered to provide high output torque and low inertia, the ICMB motor can deliver full torque from zero speed. The motors are available with a displacement range of 15,000 to 52,800cc/rev, providing torque of 240 to 840Nm/bar and rated speeds of 21 to 94rpm, depending on displacement.
The motor’s low moment of inertia and high power-to-weight ratio enable enhanced dynamic performance and help prevent damage in the event of an unexpected slowdown or stop. Its low inertia also improves dynamic response speed, decreases system pressure shock to enhance system stability, increases control accuracy, and reduces energy consumption, especially during startup and shutdown.
The motor’s overall efficiency can reach 95% or higher, resulting in lower operational and maintenance costs and reduced heat, helping extend the life of motor components.
The Vickers by Danfoss ICMB Cam Lobe Motor features a compact design, making it ideal for space-constrained applications. The motor offers flexible installation options, facilitating easy integration into a wide range of system configurations. The motor can be provided with a hollow shaft for mounting on a driveshaft via a shrink disc coupling, or with a splined internal bore for mounting on a splined shaft. A through hole provides additional application flexibility. The motor can be torque-arm or flange-mounted. Torque-arm mounting prevents the need for additional couplings, flanges, or bedplates. The torque arm and its attachment aid in motor installation and eliminate the need for alignment bearings.
Yuanjin (Stein) Wang, global product management director, pumps and motors, industrial division, Danfoss Power Solutions, said, “Our new ICMB Cam Lobe Motor is the ultimate solution for smooth, dependable performance, delivering consistent, high power in the world’s most challenging hydraulic applications. But our offering goes far beyond the motor itself. By combining the ICMB with Danfoss power units and other components, we can engineer a complete rotary drive system. And with our deep application expertise, we partner with customers throughout development to ensure the entire system is optimised and perfectly tailored to the application.”
The Vickers by Danfoss ICMB Cam Lobe Motor has been engineered for rotary drive applications, including winches, drills, conveyors, bucket wheel reclaimers, crushers, shredders, feeders/breakers, kiln drives, and pinch feed rollers. Four motor frame sizes cover the displacement range. A fifth frame size, currently in development, will further expand the range.
