US 2026/0135447 A1 · SYSTEM AND METHOD FOR MANUFACTURING HALBACH ARRAY ROTOR

Abstract

Disclosed are a system and method for manufacturing a Halbach array rotor. A system for manufacturing a Halbach array rotor according to an embodiment of the present disclosure includes a magnet pre-magnetization device configured to seat non-magnetized magnets on holders radially disposed on an index, pre-magnetize the individual magnets by using automation devices installed for respective rotation sections in one side rotation direction, and then load the magnets to a hub, a clamping jig device configured to couple the hub to a circular arrangement jig and fix the individual magnets loaded onto an outer peripheral surface of the hub by using corresponding magnet clamping units, and a controller configured to magnetize the non-magnetized magnets in accordance with orientations by collectively controlling the magnet pre-magnetization device and the clamping jig device and then assemble the magnetized magnets on the hub in accordance with a magnetization direction of a Halbach array.
