“…Therefore, a conventional electromagnetic spring brake solution was adopted (Hirzinger et al, 2001). Yasa et al (2014) have designed a brake inside a robot joint, which provides braking force via two springs. The electromagnetic suction generated by energising the coil separates the friction disc from the brake housing.…”

Abstract. An electromagnetic brake is the key basic component to ensure the safety of robot joints. The conventional electromagnetic brake mostly uses a set of springs to provide braking force and solenoid power to provide a recovery force, which makes this kind of brake with large thickness and small braking torque that is not conducive to the application in light and small joint components. In many design processes, unclear understanding of the machine-electric-magnetic coupling characteristics leads to relatively simple theoretical models and inaccurate theoretical results, which do not provide more help for subsequent designs. In this paper, a hollow-ring type permanent magnetic power-loss protection brake, integrated inside a joint assembly, is designed. The brake uses rare earth Nd–Fe–B permanent magnets to provide braking suction instead of ordinary spring packs, and achieves motion guidance and braking torque transmission by means of leaf spring. Combined with the deformation model of the leaf spring and the magnetic circuit models of the brake under the power-on and power-off conditions, the overall coupling dynamics model of the brake is established. The theoretical results are compared through finite-element software, and a prototype is produced for experimental testing. Finally, the accuracy and validity of the theoretical model are verified, providing a theoretical and experimental basis for the design of this type of brake.

“…Electromechanical brakes are commonly used in several aerospace and industrial applications [4], of course in the former applications electromagnetic brake consist on a potential component adopted in electromechanical actuators and so they must contribute to the achievement of the objectives at the basis of EMAs for MEAs, that is significant improvements in terms of weight and volume reduction, total life cycle costs, maintainability and aircraft reliability. A further important requirement that an electromagnetic brake of an EMA must have is the complete absence of interferences with sensors.…”

More Electric Aircraft has been a well-known term for a few years now. Key components for the More Electric Aircraft are the electromechanical actuators, these most of time among the other components as electric motors, sensors, mechanical components, etc. have also electromechanical brakes. This paper describes the design process of an electromechanical brake for an aerospace application and the experimental tests done to verify congruency among real electromagnetic forces and those evaluated by Finite Element Analysis.

“…Induction motors (IMs) are commonly used in a wide variety of industrial applications, because of their high robustness, reliability, easy maintenance, low cost, high efficiency and good self-starting [1][2][3][4][5][6][7][8][9][10][11][12]. The most important control parameters in a motor drive system are starting, speed control and braking processes.…”

“…These include: regenerative braking, plugging braking, dynamic braking, DC dynamic braking, zero sequence braking etc. [6][7][8][9][10][11]. The braking system technique of an electric motor is basically the removal of the stored kinetic energy from the mechanical part of the system via the speed reduction of the rotating system and the transforming of the stored kinetic energy into another energy which dissipates through heat due to joule effect losses in the rotor bars.…”

This study aims to investigate, analyze, discuss and illustrate an effective and reliable fast braking system used in a three-phase induction motor by combining two or more different conventional braking methods such as dynamic-plugging and electromagnetic-plugging. The plugging process is implemented by disconnecting one of the stator phases and connecting it with an electromagnetic brake while interchanging the other two phases. The dynamic process is executed by inserting high resistance in the rotor circuit of the motor. The performance of the torque-speed characteristics of the induction motor will be studied and analyzed through the dynamic process. Mathematical models have been developed and simulated. Results show that the braking process time is greatly reduced.
