Modern robotics is moving toward more compact, lightweight, precise, and highly integrated designs. From industrial robotic arms and collaborative robots to humanoid robots, medical robots, and automated systems, every robotic joint has specific requirements for torque, speed, size, weight, and motion control. As these requirements become more demanding, the motor can no longer be considered an isolated component. It needs to work as part of the complete mechanical and control architecture.
This is where frameless brushless motors provide an important advantage. Unlike conventional housed motors, frameless BLDC motors are designed to be integrated directly into the equipment structure. Their rotor and stator can be incorporated into a custom mechanical assembly, giving engineers greater freedom over housing, bearings, shafts, and installation space. This makes frameless brushless motors particularly suitable for robotic joints and other motion systems where compactness, precision, and mechanical integration are important. Brushless.com currently offers a range of frameless BLDC motors covering different power, voltage, and speed configurations for robotics, industrial automation, medical devices, drones, and other applications.
The medical industry demands components that combine reliability, precision, and adaptability. Frameless brushless motors meet these requirements by offering a unique balance of compact design, energy efficiency, and advanced motion control. Unlike traditional housed motors, their frameless architecture gives engineers the flexibility to integrate customized solutions directly into medical equipment. The following key advantages highlight why frameless brushless motors are increasingly adopted in surgical, diagnostic, and therapeutic devices.
In the fast-evolving world of unmanned aerial vehicles (UAVs) and drones, performance, efficiency, and reliability are key factors that determine success. From hobbyist quadcopters to high-end military UAVs, propulsion systems are the backbone of flight. Among the many innovations that have reshaped aerial technology, frameless brushless motors have emerged as one of the most advanced solutions for drone propulsion. But what makes these motors so well-suited for UAVs? Let’s explore.
When selecting a frameless brushless motor, engineers and product designers must consider several critical factors to ensure the best performance, reliability, and integration with their systems. Frameless BLDC motors, unlike traditional housed motors, are supplied as a rotor and stator set.
This design provides greater flexibility for integration into custom assemblies such as robotics, drones, aerospace systems, and medical devices. Below are the key considerations to guide your selection.
Frameless brushless motors, also known as "coreless" or "external rotor" motors, are a specialized type of electric motor that offers high efficiency, reduced size, and enhanced performance. Unlike traditional brushless motors, frameless motors do not have an external housing or frame. This makes them unique in design and ideal for applications where compactness, low weight, and high precision are critical. In this article, we will explore what a frameless brushless motor is, how it works, its advantages, and its common applications.
