Low-frequency vibration reduction motor base based on photonic crystal and manufacturing method of low-frequency vibration reduction motor base

The invention discloses a low-frequency vibration-damping motor base based on a photonic crystal and a manufacturing method thereof, the low-frequency vibration-damping motor base comprises a stator core, a motor casing and motor legs, the motor casing is in interference fit with the internal stator core and is fixedly connected with the motor legs at the bottom, and the motor legs are fixedly connected with the motor casing. First through holes which are periodically distributed around the stator core are formed in the end face of the motor shell, and the first through holes extend in the axial direction of the stator core and are used for being filled with damping materials. Through the structural optimization design of the motor base, part of metal of the base is replaced by a damping material with lower density, the weight of the base is obviously reduced, and meanwhile, on the basis of the Bragg photonic crystal principle, on the premise of ensuring that the base has enough strength and rigidity, a requi
