"PHA" Series – Inline ServoFit Gearhead "PH" Series

Description Overview Literature Links

The "PHA" Series is well suited where a smooth, precise, reliable drive is needed. The FlexiAdapt™ motor coupling is designed for accurate and precise motor installation. The integrated thermal expansion feature, in the shape of a bellows, compensates for linear thermal expansion of the motor shaft. Adapter bushings are provided when needed to fit any motor shaft.

Typical Industries: Automation, Automotive Manufacturing, Converting, Machine Tool, Medical, Packaging, Plastics/Composites, Printing, Robotics, Semiconductor, Valve Control

Special Options: ATEX Certified

Standard Features

Ground and honed gearing provides smooth running.
Balanced clamp coupling for smooth operation at high speeds.

The addition of binary ratios, 8, 16, and 32:1, simplifies control systems.
Precision selection of parts ensure optimal performance without binding gear teeth, resulting in a more accurate and smooth direct drive.

Benefits

Readily attaches to any servo motor
Backlash – 1 arc minute or less – is the result of high quality gear manufacturing, not preloading during assembly. This eliminates cogging velocity ripple and collisions that cause backlash growth.
Superior Torsional Stiffness
90-96% Efficiency
Assembled in the U.S.A.

5 Year Limited Warranty (2 years on bearings, seals, etc.)
A bellows style input coupling compensates for linear thermal expansion of the servo motor shaft by absorbing shaft length growth which normally causes a change in gear position. This compensation eliminates positioning errors enabling your machine to perform the same regardless of hot or cold temperature.
