Chapter Conceptual Design of a Soft Material Linear Switched Reluctance Motor for Soft Robotic Applications
Abstract Common actuation principles in soft material robotics require rigid components in their chain of energy conversion devices, for example fluid pumps or tendon winding motors. In a strict sense, their embodiment in a robot, can hardly be called structurally “soft”. There are other actuation principles that use elastic or pseudo-elastic materials to transform electrical power into motion in “soft” structures directly, for example shape memory alloys and electro-active polymers. Nevertheless, power limits or travel range limits, performance quality, short material life time, electrical hazards or further practical difficulties may inhibit their deployment. This need for soft actuation principles with high power density, large travel ranges, manufacturable design, robustness, and simple systems integration is the motivation for this approach. In order to establish all-soft actuators, this approach strives for direct conversion of electrical power into motion by electro-magnetism. It is the objective to elaborate the fundamentals of electro-magnetic actuators which consist of highly elastic materials so that, ultimately, such devices can be embedded into soft robot structures without disturbing the robot’s structural softness. Among the electro-magnetic motor principles, the switched reluctance motor is identified as the research subject of highest priority, because the realization of effective elastic magnetic flux guidance therein is a preliminary technology for the other, more complex electromagnetic motor principles. In order to yield the actuation force, such an actuator requires a set of coil-driven magnetic circuits, which change their inductances when the mover travels. It is proposed to realize the magnetic circuit, which has to guide the magnetic flux through the coil and the mover, by an elastic material filled with ferro-magnetic particles. Hereby, the main technical target is to maximize the amplitude change of the magnet circuit’s inductance. The key to an effective actuator design addressed by this approach lies hence in a combination of particle embedding technology in complex shapes for effective magnetic flux geometries and model-based systems engineering that considers the cross-domain complexity of such actuators. Both are supported by function- and manufacturing-oriented simulations, such as a coupled DEM simulation for particle-filled flux guidance geometries.
