Description

Stable high-speed permanent magnet synchronous motor core Technical Field

[0001] This utility model relates to the field of motor core technology, and in particular to a stable high-speed permanent magnet synchronous motor core. Background Technology

[0002] The core of a high-speed permanent magnet synchronous motor is one of the core components of the motor design, and its performance directly affects the motor's efficiency, power density, temperature rise, and reliability. The core is made of laminated silicon steel sheets, which improves magnetic permeability by reducing eddy current losses, making it particularly suitable for high-frequency magnetic field environments under high-speed conditions. The core material must possess high mechanical strength to withstand the centrifugal force generated by high-speed rotation, and stress verification is performed in conjunction with the sheath material.

[0003] Previous high-speed permanent magnet synchronous motor cores had the following drawbacks: 1. They were inconvenient for rapid assembly, time-consuming and labor-intensive, had low overall stability, were difficult to wind, and could not improve rotor rotation stability. Therefore, those skilled in the art have provided stable high-speed permanent magnet synchronous motor cores to solve the problems mentioned in the background art. Summary of the Invention

[0004] The main objective of this invention is to provide a stable high-speed permanent magnet synchronous motor core to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The core of a stable high-speed permanent magnet synchronous motor includes end caps, a silicon steel shell, and a connecting plate;

[0007] An end cap is mounted on the outer side of the silicon steel shell by mounting bolts. A positioning guide sleeve is welded to the center of the end cap, and a positioning bearing is fitted inside the positioning guide sleeve. A circular limiting groove is provided on the inner side of the silicon steel shell. Vertical frames are provided at equal intervals between the two sets of silicon steel shells. Supporting rings are welded to both ends of the vertical frames, and the supporting rings are located in the circular limiting groove. A connecting plate is provided on the outer periphery of the silicon steel shell and close to the circular limiting groove. Pull screw holes are opened at equal intervals on the connecting plate, and pull rods pass through the corresponding pull screw holes on the two sets of connecting plates. Locking nuts are screwed on both ends of the pull rods, and the locking nuts are located outside the connecting plate.

[0008] As a further improvement of this utility model: a sealing ring is bonded to the bottom periphery of the end cap, and the sealing ring is specifically made of silicone rubber.

[0009] As a further improvement of this utility model, mounting screw holes corresponding to the mounting bolts are provided at equal intervals on the outer side of the silicon steel shell. The mounting bolts and mounting screw holes facilitate the quick fixing of the end cap to the silicon steel shell, making installation and disassembly convenient.

[0010] As a further improvement of this utility model, wire clamping plates are welded at equal intervals on both sides of the vertical frame.

[0011] As a further improvement of this utility model, triangular reinforcing plates are welded at equal intervals on the outer side of the connection between the silicon steel shell and the connecting plate. The triangular reinforcing plates effectively improve the overall strength and rigidity of the connecting plate and the silicon steel shell, making them less prone to deformation and more durable.

[0012] As a further improvement of this utility model, the connecting plate and the silicon steel shell are made of the same material and are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place the supporting rings at both ends of the vertical frame into the ring limiting grooves at one end of the silicon steel shell, and tighten and fix the two sets of silicon steel shells by means of pull rods, locking nuts and connecting plates, and position the vertical frame. The vertical frame facilitates the winding of copper wire to form a coil. The wire clamping plate limits the winding of copper wire to prevent displacement, realizes rapid winding processing and improves production efficiency.

[0015] 2. The rotor is placed inside the vertical frame and penetrates the silicon steel shell at both ends. The end caps at both ends are fixed with mounting bolts, so that the rotor bearings pass through the positioning bearings in the positioning guide sleeves, which greatly improves the stability during rotation. The iron core of this high-speed permanent magnet synchronous motor is easy to assemble quickly, saving manpower and material resources. It has high overall stability. The sealing ring is made of silicone rubber material, which has high elasticity and good sealing effect, effectively providing dustproof and waterproof effects. Attached Figure Description
