Transverse flux machines are a fascinating technology for electric motors and generators, offering exceptional performance in applications where low speeds and high torque are required. These machines thrive in environments with limited RPM, making them an ideal choice for various industries. The transverse flux concept was first introduced by W.M. Morday in 1895, who successfully secured a patent for this groundbreaking technology. TFM generators boast a unique design, featuring a single coil nestled within the iron yoke. Furthermore, it's also possible to create a three-phase generator using this configuration. As an electric motor, transverse flux machines can be used in various applications, including transportation systems such as electric cars, bicycles, scooters, and electro-skateboards. TFM generators are equally versatile, finding suitable use in wind and hydroelectric power generation. One of the significant advantages of these generators is their ability to operate efficiently at low RPM without the need for gearboxes. The benefits of transverse flux machines are numerous: - They can achieve low rotary speeds, often below 1000RPM. - High continuous torque is a hallmark of TFM technology. - Copper wire usage is optimized, resulting in significant cost savings. - These machines boast a compact design, ideal for space-constrained applications. - The overall cost-effectiveness of transverse flux machines makes them an attractive option. To assemble the printed parts, three models are required: two body caps and one rotor. Iron plates can be cut from 0.5mm thick electrical steel, providing the necessary structural integrity. Key components include: * A shaft with a bearing size of 8mm, utilizing an 608 bearing unit * Magnets measuring 10x5x5mm, featuring axial magnetization as depicted in the accompanying images * Rare-earth magnets can be sourced from reputable suppliers like Indigo Instruments (https://www.indigoinstruments.com/magnets/rare_earth/)
