ROTOR INCLUDING DIVIDED ROTOR CORE

摘要

PROBLEM TO BE SOLVED: To easily adjust an arrangement position of a divided rotor core with high accuracy.SOLUTION: A rotor 10 including a divided rotor core 11 includes: a ring member 15 which is disposed on an outer peripheral surface of the divided rotor core 11 and made of a non-magnetic material; and a friction type fastener 14 which is disposed between an inner peripheral surface of the divided rotor core 11 and an outer peripheral surface of a shaft 12, may press the divided rotor core 11 to the ring member 15, and is made of a non-magnetic material. The rotor 10 including the divided rotor core 11 enables an arrangement position of the divided rotor core 11 to be easily adjusted with high accuracy.
