[0002] High-speed motor rotor punchings are core parts for improving motor efficiency. They are usually installed at the connection parts of the motor rotor. They have the functions of conducting current and bearing electromagnetic force. They are metal sheets made of highly conductive materials (such as copper, aluminum, iron, silicon steel, etc.) stacked together. They are usually made of high-speed steel or cemented carbide. According to different shapes, motor rotor punchings are divided into circular punchings, fan-shaped punchings, pole punchings, etc. Among them, pole punchings are divided into main pole punchings, rotating pole punchings, and eddy current brake pole punchings.
