Right Angle Planetary Servo Geared Motors

A high-precision right-angle planetary gear unit for small installation spaces, combined with a highly compact, dynamic synchronous servo motor. Our right-angle planetary servo geared motors are known for high demands on smooth operation, efficiency, and service life.

Stober offers five series of right-angle planetary servo motors: PKEZ: For high precision, PKXEZ: High precision for small installation spaces, PHKEZ: For high performance, PHKXEZ: High performance for small installation spaces, PHQKEZ: Quattro Power for a high power density.

PKEZ

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 high torsional stiffness and backlash stability!

Technical Data

• Total ratio: 12 – 555

• Allowed acceleration torque: 68 – 3105 Nm

• Backlash: 1.5 – 5 arcmin

• Efficiency: 94%

PKXEZ

Right-angle planetary servo geared motors: The PKX gear unit series is the compact variant of the PK series. Just as precise and 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 – without any offset.

Technical Data

• Total ratio: 3 – 300

• Allowed acceleration torque: 11 – 3300 Nm

• Backlash: 2 – 8.5 arcmin

• Efficiency: 94 – 96%

PHKEZ

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

Technical Data

• Total ratio: 16 – 555

• Allowed acceleration torque: 89 – 7500 Nm

• Backlash: 1.5 – 4.5 arcmin

• Efficiency: 92 – 93%

PHKXEZ

Right-angle planetary servo geared motors: The PHKX series is the compact variant of the PHK gear unit series. With just as much torsional and tilting stiffness, it is robust with high-quality helical gearing and is perfect for tight installation spaces. When attached to an EZ motor, the result is a highly compact right-angle geared motor with maximum volume performance, exceptional synchronism, and high torque.

Technical Data

• Total ratio: 4 – 300

• Allowed acceleration torque: 26 – 2100 Nm

• Backlash: 1 – 6 arcmin

• Efficiency: 92 – 95%

PHQKEZ

Right-angle planetary servo geared motors – 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. STOBER right-angle planetary servo geared motors.

Technical Data

• Total ratio: 22 – 2242

• Allowed acceleration torque: 123 – 43000 Nm

• Backlash: 1.5 – 4 arcmin

• Efficiency: 90 – 93%
