BUFFALO, N.Y., April 23, 2026 — Allient Inc., a global designer and manufacturer of specialty motion, controls and power products and solutions for targeted industries and applications, has announced the release of a new whitepaper titled "A Selection Guide to Motors for Humanoid Robotics Systems."
Read the full whitepaper here.
Humanoid robotics is transitioning from research into commercial and industrial applications, increasing demand for high-performance actuation in dynamic environments. As these systems develop, actuator performance, torque density and system-level behavior are becoming more critical to overall stability and performance, reinforcing the importance of motor selection.
This whitepaper examines how actuators enable locomotion, manipulation, balance and interaction in humanoid systems. It also outlines key motor technologies including frameless, slotless, geared and direct-drive designs. Core performance factors such as torque density, inertia, response behavior and thermal constraints are covered in compact actuator environments, alongside system-level challenges, joint-level selection considerations and emerging trends in humanoid actuation.
Allient applies decades of expertise in motor and motion technologies to support humanoid robotics systems in dynamic, real-world environments, delivering high torque density, precise control and compact integration.
“Motor selection has a direct impact on humanoid system performance,” said Robert Mastromattei, Chief Commercial Officer & Group President at Allient. “This whitepaper highlights key considerations in humanoid actuation and offers insight into selecting motors across different joint functions.”
