Product Details Supplier Info More products

The Hägglunds CBM from Bosch Rexroth is a very large, heavy-duty hydraulic motor that eliminates the need for gearboxes and provides direct drive for high-torque applications such as wind turbines, tidal stream generators and very large bulk handling and processing plant.

According to the company, the CBM direct motor delivers 50 per cent more torque, is 50 per cent lighter than its predecessor and places less weight on the drive shaft to provide an extremely high torque-to-weight ratio.

The motor is said to deliver full torque from zero, protection from shock loads and four-quadrant operation. It utilises the Hägglunds DU drive unit to provide infinitely variable speed, as well as accurate load control and fast response to the low inertia.

Key features and benefits

  • The drive caters for heavier workloads, takes up less space and reduces weight on the drive shaft.
  • It offers reduced installation requirements and provides higher productivity.
  • A splined hollow shaft eases the attachment to the driven shaft.
  • Direct retrofit kits are also available.
