Variable Displacement
Staffa Smart Motor
Prototypes now available
- Closed loop electronic displacement control: any displacement is possible between motor max and min, offering multiple operating modes from 1 hydraulic motor
- Continuously variable displacement: hydraulic motor reliability, but now with the controllability that was only previously available from an electric drive & inverter
- Electronic communication to and from the motor: easily access data on motor speed, torque, shaft power, displacement; as well as being able to use this data to control the motor – for example set the motor to hold a torque value
HMF Motors – Triple Displacement
Our HMF radial piston motors have three pre-set displacements which can be selected from a wide range to suit specific application requirements. The motor was originally designed to allow 2 standard operating modes, and a 3rd ‘freewheel mode’ in case of emergency release – but the HMF series can equally just be used as a 3 speed motor. The motor displacement can be changed with ease while the motor is running and under load.
- 3 displacement modes
- 1,475 to 5,326 cc displacements in 4 frame sizes.
- Freewheel option available
- Dynamic displacement change
- Speed sensing options
HPC400 Motor- High Power Quad Displacement
Based on the high power dual displacement HPC range of motors; the HPC400 has two eccentric drums which can be independently moved between high and low displacement – therefore offering customers 4 operating speeds. As with all Staffa motors the HPC400 offers high starting torque, smooth operation at low speeds and unrivalled reliability.
- Max. continuous power of 430 kW
- 250 bar continuous pressure rating
- Dynamic displacement change under load
- Freewheel Option available
- Rated Torque of 25,000 Nm
