Applications
Q: What are the differences between a frameless BLDC motor and a traditional housed (framed) BLDC motor?
A: A frameless BLDC motor consists only of the stator and rotor components, without an outer housing or bearings. It is designed to be directly integrated into the mechanical structure of the application, such as robotic joints or custom assemblies. In contrast, a traditional housed BLDC motor includes a complete enclosure, bearings, and mounting features, making it a plug-and-play solution for general applications. Frameless designs allow BLDC motors to achieve higher power density, compact size, and greater design flexibility, but they require precise mechanical integration and custom thermal management by the end user.
