Developed an amorphous alloy laminated adhesive ribbon for motor cores

While amorphous alloys can significantly reduce iron loss, mass production is limited to the axial gap type*1 due to their high hardness and thin material. In response to this challenge, Proterial developed a technology for continuously laminating and bonding multiple amorphous alloy ribbons for radial gap type*2 motor cores. Our unique bonding technology has achieved a high packing density of over 90%, enabling lamination without compromising the magnetic properties of the amorphous alloy. It is contributing to the popularization of motors using amorphous alloys by solving the problem of thinness and the challenges presented in the punching process by optimizing the mold material.
- *1Axial gap type: A motor with a stator sandwiched between two disk-shaped rotors.
- *2Radial gap type: A type of general-purpose motor in which the stator surrounds a cylindrical rotor.
