Rotary Actuators

Rotary Actuator

Rotary actuators utilize brush and brushless type DC motors using both neodymium and rare earth magnets. These units have been designed with separate or imbedded analog or digital amplifiers, spur gearing and potentiometers as feedback devices. Typical applications include Unmanned Aerial Vehicles (UAVs), Remotely Piloted Vehicles (RPVs), target drones, utility aircraft applications and Advanced Air Mobility (AAM).


Moog has been developing specialized high technology and utility electromechanical actuators for over 35 years. Our capability includes in-house design, manufacturing expertise, engineering support and qualification for these products.

Products range from 25 to 2,500 in-lb for rotary and 100 to 2,000 lbf for linear configurations. We can offer our assemblies with integral servo control electronics. Moog offers a variety of communication interfaces including analog, (+/- 10 VDC for example), RS232 / 422 / 485, R/C PWM and CAN Bus. We design for redundancy if required by our customer.

Moog is a FAA certified repair station and can offer hardware in support of repairs, upgrades or overhauls.

Custom Designs and Specifications

Moog’s experience makes us familiar with numerous types of rotary electromechanical actuation requirements. We offer our customers a solution from dozens of product configurations or a baseline design. We recognize that it is not always possible to utilize an existing design, so we are equally comfortable in offering customization to meet individual customer needs. Customizations often include expanded angular deflection, unique mounting provisions and/or relocation of connectors or other mechanical parts. Moog works closely with each customer to help select the appropriate model with a focus towards meeting program milestones and goals.

Moog is committed to work with our customers in providing a solution to customer specific requirements if an existing design is not available. We are experts in design, development, qualification and certification. In addition to the hardware development, our sites include program management professionals who can support SDRL creation, milestone reporting and overall risk mitigation. Moog offers extensive engineering experience in mechanical, electrical and system disciplines to our customers.
