Magnet-embedded rotor, method for manufacturing the same, and magnetization device

摘要

A magnet-embedded rotor (4) includes a rotor core (40) that rotates together with a motor shaft; and permanent magnets (50) embedded in the rotor core (40). The rotor core includes paired core members. A first core member includes a tubular portion into which the motor shaft is inserted and two projecting portions formed to project in a radial direction of the tubular portion from an outer periphery of the tubular portion. A second core member includes a tubular portion and projecting portions as well as the first core member. The rotor core (40) is formed by assembling the paired core members. The permanent magnet (50) is embedded in each projecting portion of each core member.
