How to control motor systems in fully enclosed environments without batteries, controllers or power cables? We present a highly integrated wireless ultrasonic motor system designed to wirelessly power and control motors in such environments. Our innovative system features a single integrated magnetic coupler connected to the motor, achieving remarkable simplicity and integration.

Key benefits:
• Battery and cable free: Eliminates the need for batteries and cables, reducing maintenance.
• Controller and sensor independence: Operates without additional controllers or sensors, streamlining design.
• Modular design: Easily adaptable to various applications, facilitating seamless integration.

Our system is ideal for environments where traditional cabling is impractical, such as in robotic arms, thereby enhancing mobility and flexibility. In enclosed environments such as underground pipelines or underwater propellers, it avoids complications from perforated installation cables, preventing gas or liquid leaks. This innovation offers new solutions for advanced applications in robotics and industrial automation.
