Hagglunds Hydraulic Motor & Pump

The Hägglunds CA hydraulic motor was developed for a specific purpose: to provide high torque from a small package. Offered by Bosch Rexroth, the Hägglunds CA motor can mount directly onto the driven shaft, an arrangement that makes it much smaller and lighter than the next-best alternative—an electric motor driving a shaft-mounted gear reducer though a belt drive.

A Hägglunds CA motor delivers continuous high-torque power continuously, and the motor’s low inertia allows effective torque limitation from zero to maximum speed. It’s especially well-suited to winch drives due to its fast-acting pressure control that minimizes transients of strain. It also achieves four-quadrant operation—driving and braking in forward and reverse.
