Rotary Actuators

Harmonic Drive offers rotary actuator products that maximize torque while inherently possessing high positional accuracy. Our extensive in-house design and build capabilities enable us to design and manufacture customized actuators to meet specific application needs.

As a manufacturer of harmonic gearing and other actuator componentry including brushless servo motors, cross roller bearings, integrated drives and absolute encoders, we are uniquely positioned to combine these elements into optimal, cost-effective solutions.

These complete servo actuators prevent machine designers from having to select a motor and gearhead and characterize their expected performance. They provide the fastest solution for executing a fully operational machine design.

Available rotary drive actuator options include conventional integrated and hollow shaft versions in multiple sizes and gear ratios from 11:1 to 161:1.

Integrated Actuators Hollow Shaft Servo Actuators Actuators - without Hollow Shaft Why Partner With Harmonic Drive?

We can provide a mini actuator with an integrated servo drive utilizing CANopen® communication. The device features a single cable connection with only 4 conductors needed: CANH, CANL, +24VDC, 0VDC.

Integrated actuators have numerous industrial and manufacturing applications:

  • Robotics: Actuators assist with robot positioning and rotation. They also enable end-of-arm robotic tooling when using grippers, welding torches, sensors and other devices.
  • Automation: Rotary actuators support the function of various automated systems, such as assembly lines and packaging equipment.
  • Aerospace: These devices are essential in operating aircraft systems, like landing gear and control surfaces.
  • Fluid flow: Actuators help regulate the flow of fluids through valves in HVAC systems.

These brushless actuators feature a large hollow bore that allows wires, tubing, laser beams or other components to pass directly through the axis of rotation.

The various hollow rotary actuator applications include:

  • Robotics: The hollow shaft facilitates the routing of cables for operating a robot's manipulator arms or hands.
  • Semiconductors: The actuator's hollow shaft can also accommodate wiring and tubing for inspection equipment and wafer handling systems used in semiconductor manufacturing.
  • Automation: Actuators enable the routing of pneumatic lines and cables for factory automation equipment.
  • Machine tools: Milling machines and similar equipment can use hollow shaft actuators to permit the running of sensor cables and coolant lines.
