Reduces Complexity & Cost, Improves Performance, Supports Next-Gen Architectures
DETROIT, MI / ACCESS Newswire / June 16, 2026 / Leggett Dynamics today launched its Smart Brushless Motor, a next-generation motion system that simplifies design and vehicle integration, improves NVH and durability and supports evolving software architectures across seating and other motion-control applications.
Less Complexity, More Capability
Unlike conventional systems, Leggett Dynamics' Smart Brushless Motor can operate with or without a seat-level electronic control unit (ECU), enabling direct communication from the vehicle-level ECU to individual actuators. This streamlined approach supports the industry shift toward more centralized or zonal architectures and enables simplified, scalable integration across multiple seat configurations and trim levels with varying actuator counts.
In addition, the motor's design reduces packaging size, weight, and wiring complexity while enhancing sound, durability, and electromagnetic compatibility (EMC) performance.
Smarter Motion, Enhanced Comfort
For vehicle occupants, these engineering gains translate into a better in-cabin experience. The Smart Brushless Motor enables quieter operation, smoother seat adjustment, faster memory recall, and a wider range of motion. The result is precise, reliable comfort and motion that feels responsive and refined in everyday use.
"Leggett Dynamics' Smart Brushless Motor is about doing more with less: less components, less complexity, less weight and less noise while achieving more capability and more adaptability for manufacturers and more comfort and motion control for consumers," said Julien Rea, VP of Global Innovation & Engineering at Leggett Dynamics.
The Smart Brushless Motor enters the market as OEMs transition to software-defined vehicles, centralize architectures, and pursue simplified and commonized hardware across platforms paired with software-enabled updates. It also addresses growing demand for quiet, scalable systems across mixed propulsion portfolios, particularly in EVs, where cabin quietness makes motor noise more apparent.
Leggett Dynamics will showcase its brushless motor and other comfort and motion innovations at two upcoming industry events: The Automotive Engineering Expo in Nagoya, Japan (June 17-19, Booth 96) and Automotive Interiors Expo Europe in Stuttgart, Germany (June 23-25, Booth #3216).
