A A frameless motor is a housingless brushless motor consisting of a separate stator and rotor. It generates torque through electromagnetic interaction and is designed to be directly integrated into a customer’s mechanical system.
-
A Frameless motors are supplied without a housing, shaft, or bearings, allowing system designers to define their own mechanical structure, feedback, and cooling instead of relying on a fixed motor package.
-
A They provide high torque density, zero backlash, and direct-drive performance, making them ideal for applications where accuracy, stiffness, and smooth motion are critical.
-
A Yes. By eliminating gearboxes and mechanical transmission losses, frameless motors can significantly improve overall system efficiency.
-
A Direct drive removes backlash and compliance, resulting in higher positioning accuracy, faster response, and improved dynamic behavior.
-
A Very little. Without brushes or gear trains, mechanical wear is reduced, leading to lower maintenance requirements over long operating periods.
-
A Yes. With proper motor sizing and thermal design, frameless motors support continuous and long-duty industrial operation.
-
A Yes. Smooth electromagnetic torque generation and gearless operation result in low noise, minimal vibration, and stable motion.
-
A Yes. Frameless motors are specifically designed to deliver high torque at low speeds, often without the need for a gearbox.
-
A Yes. When combined with suitable motor drives and encoders, frameless motors enable precise control of torque, speed, and position.
-
A Frameless motors can operate efficiently across a wide speed range, from slow, controlled motion to higher rotational speeds depending on system design.
-
A Some applications support sensorless control, but encoder feedback is typically recommended for high-precision motion control systems.
-
A Yes. Their simplified mechanical structure and robust electromagnetic design make them suitable for industrial, automation, and challenging operating conditions.
-
A Frameless motors are commonly used in robotic joints, direct-drive rotary tables, medical equipment, semiconductor machines, and precision automation systems.
-
A High efficiency, direct torque transmission, and reduced mechanical losses contribute to lower energy usage and improved system efficiency.
-
A Yes. Frameless motors are available in a wide range of diameters and torque levels to support compact, medium, and heavy-duty direct-drive applications.
-
A Yes. Electrical parameters, winding design, voltage levels, and mechanical interfaces can be tailored to meet specific system requirements.
-
A Yes. We provide engineering support, customization services, and stable long-term production for OEM and system integration projects.
