It is a cogging-less synchronous motor with "ultra-high speed," "large capacity," and "high efficiency."
We handle the "Halbach NR Motor," which is a motor that utilizes the Halbach array formed by rotating the magnetization direction of permanent magnets. Our design leverages the characteristics of the Halbach array, allowing for configurations such as high-speed rotation, low torque ripple, and high efficiency. Additionally, the shape of the yoke and coils is a key point, and we design with various phenomena in mind, such as mirror image effects and proximity effects, to suppress losses and vibrations. 【Features】 - Low-loss design that reduces the amount of iron used compared to IPMSM - Smooth operation even at low speeds due to being a coreless motor - Accommodates various requests regarding voltage, rotation speed, materials, weight, cooling methods, etc. - Compatible with built-in types - Offers proposals and support for drive inverters *For more details, please download the PDF or feel free to contact us.
