APPLICATION DEVELOPMENT
Evaluation and integration around joint packaging and motion requirements.
PRINTED WINDINGS
Why PCB motor?
Conventional wound coils are replaced by precision-patterned PCB conductors, enabling a thin, repeatable and highly integrated axial-flux architecture.
Slim design
Planar windings and axial-flux architecture support thin packaging for compact joints.
High-torque design
Electromagnetic, current and thermal design are optimized toward application torque requirements.
Low-vibration design
Design addresses torque ripple and electromagnetic excitation for smooth rotation.
Robotics and collaborative robots are the primary focus, with potential extensions to HVAC, small fans, pumps, fluid-transfer systems and premium appliances.
Manufacturing efficiency, high torque and low vibration are development objectives. Comparative performance is evaluated through defined test conditions and measured results.
LOW INDUCTANCE
A fundamental challenge of PCB motors
Low phase inductance can increase current ripple and complicate control. Adding external inductors introduces components and volume, reducing the packaging advantage in a compact robotic joint.
- PCB stator
- Low phase inductance
- Higher current ripple
- External inductor
- Additional system volume
FLUXMOTION TECHNOLOGY
Integrated inductance technology
Addressing low inductance while preserving the thin and lightweight advantages of PCB motors. The technology uses PCB patterns and an integrated fastening structure with a magnetic-core function.
CONVENTIONAL PCB MOTOR
- PCB stator
