“…Linear motor is a power device that directly converts electrical energy into mechanical energy with linear motion [22]. Compared with the traditional driving method of "rotating motor + ball screw", the linear motor has the advantages of simpler structure, more reliable operation, faster dynamic response and higher control accuracy [23]. Halbach array is an arrangement of permanent magnets, which can effectively improve the thrust of the linear motor [24].…”

The brake-by-wire actuator was considered to be the next generation of vehicle brake, which uses cables to transmit signals and energy, and uses electric motor instead of hydraulic element or pneumatic element. This paper designs a new type of brake-by-wire actuator based on the special linear motor. First, the structure, composition and working principle of the linear motor are explained. Secondly, the caliper structure and amplification mechanism of the actuator are designed. Thirdly, the controller and control strategy based on dSPACE platform are introduced in detail. Finally, the electromechanical parameters of actuator were identified, and the experiment of the linear motor and brake-by-wire actuator were completed. The experiment results show that the new actuator has the advantages of fast braking response, low control difficulty and high control accuracy, etc. In conclusion, this paper provides a new design scheme for the brake-by-wire actuator, and has the potential to further research and replace the traditional hydraulic braking system.

“…The operation, design and modeling of rotating, linear and tubular machines is quite similar (e.g., torque ripple in rotating machines versus force ripple in the linear case), that is why this review is mainly focused on rotating machines. Nevertheless, linear [4,9,10,21,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] and tubular [11][12][13]33,[42][43][44][45][46][47][48][49][50][51][52][53][54] TFMs have specific applications that are presented at the end of this section. In any case, commercial exploitation of TFMs is currently limited to very few manufacturers [55][56][57].…”

“…Similar to rotating TFMs, linear TFMs show high force density, but also high force ripple [29]. Linear TFMs have been proposed for transportation [21,27,34,40], Steltzer machines for hybrid electric vehicles [28], 3D-printer motors [30], needle free jet injection [32], servo applications [4] and electromagnetic launchers [37]. Besides, tubular TFMs have been presented for long stroke applications [11,13,54], electromagnetic launchers [46,47], and for precision industrial processing [50].…”

High torque and power density are unique merits of transverse flux machines (TFMs). TFMs are particularly suitable for use in direct-drive systems, that is, those power systems with no gearbox between the electric machine and the prime mover or load. Variable speed wind turbines and in-wheel traction seem to be great-potential applications for TFMs. Nevertheless, the cogging torque, efficiency, power factor and manufacturing of TFMs should still be improved. In this paper, a comprehensive review of TFMs topologies and design is made, dealing with TFM applications, topologies, operation, design and modeling.

“…In 1986, Professor Herbert weh proposed the transverse flux permanent magnet motor (TFPMM) firstly, which realized the electromagnetic decoupling and solved the spatial competition between slot sections and stator teethes. Therefore, its torque density could be improved greatly [2,3]. The extensive research have been made by many scholars [4][5][6][7],which promotes the development of electric vehicle industry greatly.…”

Building-block transverse flux permanent magnet motor(B-TFPMM) has the characteristics of low-speed high-torque and small axial size, which is suitable as the hub motor of direct-driving electric vehicle. However, the torque ripple of B-TFPMM is large, which would affect the driving safety and riding comfort. To optimize the motor torque, the topological structure and working principle of B-TFPMM are analyzed firstly, and the analytical model of B-TFPMM torque ripple rate is derived. Then, two quantum genetic algorithms (QGAs) with different evolution processes are presented, an optimal individual selection scheme considering the torque ripple and the average torque simultaneously are proposed and the main motor sizes that affecting the torque ripple are optimized. The result shows that one of the strategies has more obvious suppression effect on torque ripple, while the other one has more obvious optimization effect on average torque. Therefore, the appropriate strategy could be selected according to the specific need.Keywords: Quantum genetic algorithm • Building-block transverse flux permanent magnet motor • Torque optimization • Motor design
