Right-angle planetary servo geared motors
High-precision right-angle planetary gear units for small installation spaces, combined with extremely compact, dynamic synchronous servo motors.

Round the corner at full force: Right-angle planetary servo geared motors.

A high-precision right-angle planetary gear unit for small installation spaces, combined with an extremely compact, dynamic synchronous servo motor.

Our right-angle planetary servo geared motors – for high demands on smooth operation, efficiency and service life.

BENEFITS
Right-angle planetary gear unit feat. EZ motor

If the coaxial design of a motor forms interference contours, the STOBER planetary gear unit 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 gear unit – even for tight installation spaces – combined with an extremely compact, highly dynamic synchronous servo motor.

PKEZ: For high precision

The PK series consists of precise right-angle servo gear units 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!

PKXEZ: High precision for small installation spaces

The PKX gear unit 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 gear unit and rugged planetary output stage – and without any offset.

PHKEZ: For high performance

The PHK gear unit series stands for high-performance right-angle servo gear units with high-quality helical gearing and very high torsional and tilting stiffness.

Compared to the PHKX series, the PHK gear units 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 gear unit and a ruggedly mounted planetary output stage featuring high torque.

PHKXEZ: High performance for small installation spaces

The PHKX series is the compact variant of the PHK gear unit 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.

PHQKEZ: Quattro Power for a high power density

PHQK: An innovative 4-planet right-angle servo gear unit with high-quality helical gearing and very high torsional and tilting stiffness.

The same is true for the Quattro Power gear unit – 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.
