Rotary Electromagnetic Micromotors (REM) are miniature motors that operate based on the principles of electromagnetic interactions. They hold great potential for various applications in microelectromechanical systems (MEMS), offering precise rotary motion at a microscale level. REM micromotors are still in the introductory stages of development, and extensive research and development efforts are ongoing to enhance their performance and address various technical challenges. The technical literature in this area is relatively limited, indicating that REM technology is still an emerging field with considerable scope for exploration and innovation. In this article, we present REM MEMS as quoted in academic articles and explore their presence in the REM market. Given that most articles on REM MEMS do not provide parameter values, we proceeded to assess the performance parameters of 84 market DC micromotors. These evaluations covered a range of 19 weight scales (from 0.35 g to 16.1 g) and diameter scales (from 4 mm to 26 mm). The specific micromotors chosen for the analysis were from Maxon and Faulhaber, two well-known and reputable manufacturers in the field of micromotors. Consequently, we conducted a comparison of the operating parameters of the micromotors, specifically focusing on the ratios of mass to output power and torque, as well as the ratios of energy efficiency to output power and torque. Power and torque are fundamental measurements used to evaluate the performance of REM motors in the market. These curves and correlation coefficients can serve as a valuable reference for engineers and designers when making informed decisions regarding motor selection for specific applications.

Electromagnetic devices (EMDs) containing permanent magnets are common devices showing low power consumption , small size, and high sensitivity. In batch production of EMDs there is a robustness problem linked to the migration of the working point of permanent magnets and to their manufacturing uncertainties. In turn, the design optimization for EMDs has attracted large attention. Robust design optimization (RDO) is one of the most effective methods to boost quality and robustness of EMDs. However, state-of-art RDO methods ignore the various uncertainties from manufacture processing, production environment, and working point migration of permanent magnets. To address those problems, this study presents an efficient and universal method based on the working point migration and various uncertainties of output characteristics for electromagnetic devices. At first, we introduce a two-dimensional factor design scheme considering the working point migration and manufacturing conditions. Then, a robustness assessment measure suitable for different optimization types is proposed. On these bases, the optimization model is established, considering the permanent working point migration for magnets, manufacturing tolerances and robustness constraints, and a particle swarm algorithm is used to obtain the solution. Finally, the effectiveness of the method is verified by a case study involving a specific type of electromagnetic device with permanent magnets.
