The CHA and FHA-C Series hollow-shaft actuator combines a maintenance-free motor and back-free Harmonic-Drive gear in a very compact design. The unique feature of this series is the central hollow-shaft, which enables cables, pipes, shafts, spindles or laser beams to be passed through the actuator. The new CHA Series is the increased-performance advancement of the FHA-C Series.

The CHM motor "made in Germany" is based on a customized frameless motor for easy integration. Sensors for position, speed, acceleration and torque feedback are available to provide an optimized implementation in your machine design.
The new FHA-C mini mini Series is presently the most compact hollow shaft actuator series available. The CobraDrive is a fusion of the FHA-C mini and a servo controller. It provides a decentralized actuator unit for efficient installation.
The FFA-A/-B Series compact actuators combine Harmonic Drive precision gearing with AC servo motors in a compact design. A choice of resolver, incremental encoder or absolute encoder makes this actuator compatible with a wide variety of available servo controllers. The LynxDrive series servo actuators combine Harmonic Drive precision gearing with AC servo motors with concentrated winding in a very compact design. FFA-C series actuators are available with maximum output torques from 27 Nm up to 647 Nm and standard reduction ratios ranging from 30:1 up to 160:1 providing maximum output speeds of up to 217 rpm.
The FPA Series compact actuators combine Harmonic planetary gearing with AC servo motors in a compact design. A choice of resolver, incremental encoder or absolute encoder makes this actuator compatible with a wide variety of available servo controllers. Matching to the FHA-C, FFA and FPA series digital servo controllers are also available. These SC-610 Series drivers can be used for current, speed or position control. The controllers are prepared for 230V AC power supply and for various feedback systems.
RSF-Mini Series Servo Actuators, combining precision CSF series gearboxes with AC servo motors, offer unique features unsurpassed by conventionally geared drives. Used in highly demanding industrial servo systems they are providing precision motion control and high torque capacity in a very compact package. Sine commuted AC servo motors provide smooth torque over a wide speed range, without showing brush wear, as known from DC motors. Encoders, mounted directly onto the motor shaft, provide position feedback information. The backlash free Harmonic Drive gear is provided with grease lubrication specially developed to ensure minimum maintenance requirements and long service life.
The HA-680 servo controller has been specially developed for the RSF and FHA series. These digital servo controllers are designed for 24VDC and can control current, speed or position.
The PMA DC servo actuators are be based on proved DC technology and are equipped with encoders guaranteeing sensitive speed and position control. The TorkDrive torque motors offer an exceptional power density. They are specifically designed for direct drive applications where dynamic capabilities, accuracy and stiffness are paramount.
