Compact servo actuators from Harmonic Drive

15 June 2014

Harmonic Drive has combined accuracy, compact design and reliability to create the LynxDrive range of compact servo actuators.

LynxDrive combines a compact synchronous servo motor, feedback sensor and a high-precision Harmonic Drive HFUC series gear unit with high capacity output bearing. Key advantages include low energy consumption and a compact design that enables the actuator to be installed in space-limited applications. 

The sinusoidal commutated ac servo motor provides a smooth torque profile over a wide range of speeds. LynxDrive has a torque range of up to 647Nm and a maximum speed of 283rpm. The encoder or resolver feedback system provides accurate measurement of speed and position, while the temperature sensors integrated into the motor windings provide overload protection.

LynxDrive is compatible with most third party controllers operating from 230-400Vac supplies, including Harmonic Drive’s fully digital YukonDrive servo controller.

The high stiffness cross roller bearing used in the LynxDrive servo actuators was developed expressly to withstand high axial and radial forces, as well as high tilt moments. The bespoke bearing also protects the gear from external loads, which guarantees a long life and consistent performance. Removing the need for additional output bearings also simplifies installation and assembly.
