Right-angle planetary servo geared motors: If the coaxial design of a motor forms interference contours, the STOBER planetary gearbox combined with a helical bevel geared motor is the ideal solution to meet the highest demands in terms of dynamics, backlash stability and ruggedness.
You get a precise right-angle servo gearbox – even for tight installation spaces – combined with an extremely compact, highly dynamic synchronous servo motor.
The PK series consists of precise right-angle servo gearboxes with high-quality helical gearing – for exceptional backlash stability. And for large gear ratios.
When the PK series is combined with our extremely compact, highly dynamic EZ motor, the result is a precise right-angle servo geared motor featuring a high torsional stiffness and backlash stability!
Right-angle planetary servo geared motors: The PKX gearbox series is the compact variant of the PK series. Just as precise and also featuring high-quality helical gearing, it is extraordinarily stable against backlash and perfect for tight installation spaces.
When combined with an EZ motor, the result is a very compact, highly dynamic drive unit with a right-angle gearbox and rugged planetary output stage – and without any offset.
The PHK gearbox series stands for high-performance right-angle servo gearboxes with high-quality helical gearing and very high torsional and tilting stiffness.
Compared to the PHKX series, the PHK gearboxes are ideal for larger gear ratios!
With the combination of PHK and an EZ motor, you get a dynamic, highly rigid drive unit consisting of a pre-mounted right-angle gearbox and a ruggedly mounted planetary output stage featuring high torque.
Right-angle planetary servo geared motors: The PHKX series is the compact variant of the PHK gearbox series. With just as much torsional and tilting stiffness, it is absolutely powerful with high-quality helical gearing and perfect for tight installation spaces.
When attached to an EZ motor, the result is an extremely compact right-angle geared motor with maximum volume performance, exceptional synchronism and high torque.
Right-angle planetary servo geared motors – PHQK: An innovative 4-planet right-angle servo gearbox with high-quality helical gearing and very high torsional and tilting stiffness.
The same is true for the Quattro Power gearbox – it is ideal for large gear ratios.
And when it’s combined with an EZ motor, you get a geared motor with outstanding precision, very high performance, and very low backlash. STOBER right-angle planetary servo geared motors.
