The performance of miniature mechatronic systems can be significantly improved by incorporating the magnetorheological (MR) fluid-based rotary brake. However, small-size effect becomes evident in process miniaturization. Our observation indicates that a MR brake exhibits slight eccentricity 0.43 mm when its rotational axis is runs at speed 16,000 rpm. maximum torque error between compound motion model and calculated dynamic based on experimental rotation n reached 47.4%, average rate only...
Abstract Miniature turbine generators, which can supply power to miniature mechatronical system by converting natural energy, are promising for future applications in micro-aircraft, ammunition, and missiles. However, generators at the risk of rotor wear circuit failure under high wind-penetration conditions. As feature size decreases, conventional sensors hardly be integrated microsystems, making control more difficult. In addition, microspace demands higher practicality strategies....
Abstract Miniaturization has increasingly become a crucial prerequisite in various magnetorheological (MR) drive application scenarios. Owing to their high controllability and low response time, MR rotary actuators are developed for numerous feasible actuation solutions. However, the incident degradation efficiency miniaturization limits of actuators. In addition torque capacity, structural simplification easy machinability also essential miniaturization. this study, novel lamellar...
How to combine phase transition properties of magnetorheological (MR) material with control strategies in a micro-space is the key promote application micro rotary mechanical system. Current are mainly developed for large-scale actuators, which energy conversion efficiency different from that miniature MR actuator. This study proposes threshold-feedback overload protection strategy turbine generator. Sensorless generator's rotational speed also by directly capturing frequency output voltage....
