Description

technical field [0001] The invention relates to the field of heat treatment of rotor cores of reluctance motors, in particular to a heat treatment device and method for high-speed rotor cores of dual-performance reluctance motors. Background technique [0002] The increase of the speed of the aircraft motor can effectively increase the power density of the motor. The rotor core of a high-speed motor rotates at high speed and will bear huge centrifugal force, which requires the material of the rotor core to have high yield strength. Iron-cobalt-vanadium soft magnetic alloy has the characteristics of high saturation flux density and is widely used in aerospace motors. At present, the saturation flux density of iron-cobalt-vanadium soft-magnetic alloy is 2.4T, the coercivity is below 125A / m, and the yield strength is 360Mpa. , its mechanical strength is difficult to meet the development of high-speed motors. Iron-cobalt-vanadium soft magnetic alloy can effectively increase th...
