Variable-speed drive solutions control the drive motor so that kinetic energy is provided according to requirements. <br />The drive controller with its three-phase motor is the core of variable-speed drive solutions. This controller either powers a hydraulic system or the spindle drive of an electromechanical cylinder.<br />This technology makes extensive customisation of traditional hydraulic systems possible and, through this, achieve efficiency, such as: Reduced power and cooling requirements, lower tank and oil volumes, less material and lower weight.<br />Be it electromechanical cylinders or hydraulic systems: Variable-speed drives make it possible to network drive systems and make control tasks, commissioning and troubleshooting significantly easier.<br />

The HFI-MM (HYDAC Frequency Inverter - Motor Mounted) drive controller is a frequency inverter for three-phase asynchronous motors for speed control.<br />Its key advantage is that it can be attached directly to the asynchronous motor like a backpack. This means there is no need for a control cabinet and fewer tasks need to be performed on electrical systems. The advantages of a variable-speed asynchronous motor are retained.<br />This drive controller is available in performance classes from 0.55 kW to 22 kW<p> </p>

The new HYDAC EcoPack is a power unit product portfolio with variable-speed drive as a decentralised stand-alone solution, for supplying hydraulic actuators individually as needed. Depending on the duty cycle, the function and the supply voltage on the machine, we supply the EcoPack with an air- or a water-cooled motor in a voltage range of 24–400 VDC. The motor’s variable-speed functionality is realised by a speed transmitter communicating with the inverter. Furthermore, the inverter can be integrated into the machine’s CAN bus system (CANopen or SAE1939). In conjunction with HYDAC controllers (TTC), the EcoPack can also be incorporated into the machine architecture as a stand-alone system with its own controller.

The new HYDAC EcoPack+ is a power unit product portfolio with variable-speed drive and application software as a decentralised stand-alone solution, for supplying hydraulic actuators individually as needed. Depending on the duty cycle, the functions and the supply voltage on the machine, we supply the EcoPack+ with an air- or a water-cooled motor as a plug and play solution in a voltage range of 48–400 VDC. <br />Thanks to the software that was specially developed for the EcoPack+, manufacturers don’t need to worry about finding an efficient operating strategy. The EcoPack+ was specially developed for load-sensing systems and only requires a hydraulic load-sensing signal from the work hydraulics as requirement feedback, which makes it independent from the type of pilot control. Thanks to the application-specific operating strategy and the integrated power management, the machine manufacturer benefits from reduced complexity in the machine architecture.<br />
