摘要：
This article proposes a novel PM-electromagnet brake with rolling balls embedded in the friction plate, which has significant advantages of higher torque-to-size ratio, lower power consumption, and quicker brake response speed. The structural innovations of the proposed brake are mainly reflected in the following two aspects: 1) the torque springs are replaced by high-performance PMs to reduce power consumption during Brake-Holding Mode and 2) rolling balls are embedded in the friction plate to increase the braking torque. In addition, an optimized brake circuit is designed to improve the brake response speed by shortening the inductor discharging time. First, the structural innovations of the proposed brake are presented and discussed in detail. Then, theoretical analysis mainly focuses on the following two aspects: 1) how the rolling-ball-embedded structure can improve the torque-to-size ratio and 2) how the distributed PMs can reduce the power consumption during Brake-Holding Mode. At last, the optimized brake circuit is given. To verify the benefits of the design, a proposed brake prototype is manufactured, as well as the optimized brake circuit. The experimental result is promising, and the proposed brake is suitable for various applications.
