An object of the present invention is to provide a motor rotor support suitable for an axial gap motor and a method for manufacturing the same. The motor rotor support for supporting a magnetic body disposed on a rotor of the motor is configured by laminating single materials each formed from a hot-worked material or a cold-worked material preferably composed of an 18Mn-18Cr nonmagnetic steel.

Motor rotor support and method for manufacturing same

An object of the present invention is to provide a motor rotor support suitable for an axial gap motor and a method for manufacturing the same. The motor rotor support for supporting a magnetic body disposed on a rotor of a motor is configured by a nonmagnetic steel having a relative permeability of less than 1.005 and a 0.2% yield strength at room temperature of 550 MPa or more.
