The MA-h Harmonic Actuator is a robotic actuator that integrates a brushless motor, a harmonic reducer and the MD series controller with an embedded absolute encoder. It can also be equipped with an additional absolute output encoder and an electromagnetic brake, as well as being housed in an IP66 sealed enclosure. This design ensures exceptional accuracy and repeatability with zero backlash, making it ideal for applications requiring precise positioning. The actuator provides high torque density - it manages demanding loads while maintaining a compact size. The actuator is characterized by low backdrivability and exceptional stiffness. Additionally, the high durability of the harmonic reducer ensures a long lifespan. While the system may be more costly, its outstanding capabilities justify the investment. The downside of such a system is low backdriveability. This makes the MA-h Harmonic Actuator an excellent choice for mobile robotics applications where high torque density and precision are crucial.

Robotic arms
A harmonic reducer-based actuator is ideal for robotic manipulators due to its high torque and compact design. Its smooth, efficient operation and solid design ensure immaculate and reliable performance. The actuator is characterized by outstanding accuracy, repeatability and stiffness, thanks to the reducer design with zero backlash. High torque density allows it to be used in lightweight collaborative robots (cobots).
Exoskeletons
A harmonic reducer is an excellent choice for exoskeletons due to its high torque density, which provides powerful and unrestricted assistance to the wearer’s movements. Precise torque and position control contribute to accurate, natural movements, enhancing the exoskeleton’s performance and comfort. It's especially useful for upper body exoskeletons to precisely support the user's hands.
Aerospace and aviation
Harmonic reducer-based actuators are great for aerospace and aviation due to their exceptional precision, high torque density and compact design. The zero backlash characteristic ensures highly accurate and reliable movements, which are essential in critical applications. The compact size and lightweight nature of harmonic reducers are ideal for the weight-sensitive requirements of aviation and space missions. Additionally, their robust construction ensures long-term durability and reliability in demanding environments where maintenance possibilities are limited.
Automation
A harmonic actuator is ideal for industrial automation due to its unique parameters, which eliminate backlash and ensure highly accurate and smooth movements. The very high torque density allows it to be used in the most demanding scenarios. The reliable design of the actuator reduces maintenance needs and enhances its lifespan.
