These electromechanical actuators have many superior performance features including zero backlash, high accuracy, fast response time, high vacuum compatibility, and are available in a wide range of sizes, and hollow shaft designs. These servo actuators are easy to use and offer quick implementation.
They are compatible with most industry-standard controllers and amplifiers.
Servo actuators are an assembly of a brush or brushless servo motor, zero backlash Harmonic Drive® precision strain wave gearing, and a high capacity output bearing. These elements are contained within a housing.

Harmonic Drive LLC offers a complete range of digital drives for use with Brushless (AC) and Brush type (DC) actuators. Drives versions for both AC and DC power are available. Harmonic Drive® Motion (HDM) software installed on a PC is used to set-up the drives with Harmonic Drive actuator parameters. The drives can communicate via CANopen, DeviceNet, EtherCat, and MACRO. As well they can simply be operated with indexer, step/direction, PWM or + or 10V commands, or ACSII and discrete I/O.
In addition to being compatible with Harmonic Drive encoder protocols, the drives can be made available for use with many other motor manufacturer encoder formats.

These gearheads can be easily adapted to any OEM servo motor. Harmonic Drive® strain wave gearing products offer zero-backlash with gear ratios from 30:1 to 160:1. Precision planetary gearing products are available with gear ratios from 3:1 to 45:1 with backlash maintained below 1 arc-min. High capacity output bearings are utilized for robust and accurate support of loads. Other benefits include flange and shaft output configurations, hollow shaft designs, and sizes ranging from 0.625 inches to over 10 inches in diameter.

Harmonic Drive® strain wave gearing component sets are the core motion control mechanisms. These zero backlash products offer the widest design flexibility. Products can be selected which offer the optimum dimension and performance based on the available volume within the customer-designed housing. High Torque, Ultra Flat, and Hollow Shaft Options are available. Customers can use these high accuracy gearing components are core building block for custom high performance servo actuators and motion control mechanisms. Customer-supplied servo motors can be easily integrated into the design.
