Direct attachment of heavy payloads

The output bearing with high tilting capacity often allows direct attachment of heavy payloads without the need for further support, thereby providing simple and space saving design installations. To adapt to your specific application, the FHA-C Series offers many possible combinations when selecting the motor winding, motor feedback, brake, various sensors and cable as well as connector options.

Stable machine characteristics

The integrated hollow shaft can be used to feed through supply lines or services for additional axes, enabling space saving designs with minimal installation dimensions required. The accurate positioning of the actuator ensures stable machine characteristics, lower rejection rates and consistent quality. By combining the FHA-C Actuators with the specially adapted YukonDrive® Servo Controllers, it is possible to provide a single source supply for a pre-configured drive system tailored to suit your application. Alternatively, the flexible configuration of the AC actuator ensures compatibility with almost any servo controller on the market.
