DIAMET CORPORATION Product Lineup

While we want to promote the miniaturization and lightweight design of motors, we face challenges such as "increasing shaft length and weight when securing the necessary torque" and "difficulty in accommodating three-dimensional magnetic circuit shapes with electromagnetic steel sheets." In response to these design challenges, reconsidering magnetic materials and core shapes becomes a viable option. Daimet's powder core for axial flux motors takes advantage of the design flexibility of powder magnetic cores, enabling three-dimensional magnetic circuit design. We propose materials and shapes tailored to specific applications. ■ Supporting thin and high-torque designs ▼ Accommodates three-dimensional core shapes with powder cores ▼ In prototype machines, shaft length is reduced by half compared to conventional RFM ratios ▼ Maximum torque of 30Nm and maximum torque density of 8.48Nm/kg in prototype machines ■ Compatible with various motor shapes ▼ Core for axial flux motors ■ Application examples ▼ EVs, industrial robots ▼ Aircraft, eVTOL, generators This can be utilized in motor designs considering thinness, high torque density, and lightweight construction. Documents summarizing the structural and performance comparisons of AFM using powder cores, as well as more detailed benefits of achieving thinner and higher torque density motors, can be downloaded from the link below.
