In electrically powered mobile machines, losses are systematically reduced to a minimum. An example with numbers: while a conventional pump may exhibit a power loss of 5.2 kW, with the new Bucher Hydraulics AX pump the power loss under the same conditions is only 1.6 kW. Particularly with battery operation, this saves on enormously expensive battery capacity. Either the battery can be made smaller and cheaper, or its runtime can be extended by a corresponding amount, as modeling calculations and initial experience have verified.
The HELAX linear drive is also highly suitable for applications where energy can be recovered. In these cases the impact of the regenerative linear drive's high efficiency (overall efficiency up to 84%) on the energy balance is quadratic, in fact, thus enabling energy recovery in applications where previously this was not economically viable.
The on-board electronics ensure that the linear transmission can be easily controlled by the machine builder. The motion control signals are transmitted via CAN bus, for example: the software then converts the signals into the required movement. Users do not have to get involved with the detailed characteristics of the hydraulic system: they can concentrate fully on the function of their application. The hydraulic linear drive can therefore be easily integrated into the system just like any electric drive
