Hangzhou, China – December 22, 2025 — TorqueBank has expanded its motion control portfolio with custom frameless motor solutions for robotics and exoskeleton systems. These solutions are designed for direct-drive applications where torque density, compact integration, and structural rigidity matter.
Frameless motors, also known as frameless torque motors, integrate directly into the customer’s mechanical structure instead of using a conventional motor housing. This design gives engineers more freedom to optimize space, torque output, and overall system stiffness in compact precision assemblies.
Mechanical-Constraint-Driven Customization
TorqueBank currently focuses on application-driven customization rather than a fully standardized frameless motor catalog. Each solution can be developed around specific project requirements, including outer diameter, axial height, torque and speed targets, voltage range, winding configuration, and hollow-shaft or cable-routing needs.
This approach lets the motor fit the mechanical design, rather than forcing the mechanical system to adapt to a fixed motor platform.
Applications in Robotics and Exoskeletons
TorqueBank’s frameless motors are being developed for robotics and exoskeleton products, where direct-drive architectures offer clear advantages over conventional geared solutions.
In robotics joint systems, frameless torque motors can deliver high torque density in compact spaces while helping reduce backlash and improve positioning accuracy. They can also simplify mechanical integration in joint assemblies.
In exoskeleton applications, frameless motors can support more compact actuator layouts, lower system weight, and smoother torque output. These projects often require the motor to match not only mechanical limits, but also ergonomic and system-level integration needs. That is why customization is often a practical requirement, not just an option.
Development Collaboration Model
TorqueBank works with customers during the early design stage and supports a development process that may include mechanical envelope definition, performance target analysis, electromagnetic design optimization, prototype manufacturing, and iterative refinement based on system-level feedback.
As projects move forward, customized designs can be stabilized into dedicated production variants for ongoing supply.
