With the scalable modular system, the PxG® planetary servo gear units offer decisive added value for every requirement.
High speeds and torques combined with precision and efficiency: Our two series of compact planetary servo gear units offer you a huge number of possible solutions, as well as a range of motor mounting options with the EPH motor adapters for PS.F and the ECH adapters for PS.C.
With consistently low rotational clearance, high torsional rigidity and a high level of efficiency, these highly precise and extremely powerful servo gear units constitute an optimal basis for a variety of servo drives.
The PS.F planetary servo gear units are designed for nominal torques of 25 Nm to 3,000 Nm; the PS.C series is designed for nominal torques of 30 Nm to 320 Nm.
All gear ratios from i = 3 to i = 100 are integers and finely stepped. This means that the servo gear units are particularly suitable for use with controllers that require integer resolution ratios.
Only half the solution without a motor? Then take advantage of our modular concept and combine the servo gear units of the BS.F and PS.C series with the dynamic servomotor of your choice.
The availability of a digital twin helps with calculating the service life of the solutions
To ensure you are perfectly prepared for Industry 4.0, we provide a digital twin for every PxG® planetary servo gear unit (P5.G.., P6.G.., P7.G..). As all parts and components undergo 100% inspection in the production process, you can use real data to precisely calculate the service life for your planetary servo gear unit.
The unique QR code on each gear unit is the interface between the physical product and the digital world. For example, it offers access to technical documentation and other types of information.
Since the entire product concept has been newly developed and we have worked closely with our industry partners, we can offer you a whole range of additional technical highlights. These include a special development that came out of a collaboration with a prestigious partner – the Premium Sine Seal oil seal , which has been specifically optimized for this gear unit to maximize dynamics and service life.
