Technical Field
The invention relates to the technical field of motor manufacturing, in particular to a lamination method for a rotor punching sheet of a magnetic suspension motor.
Background
In the current motor technology, the rotating part of the motor, called the motor rotor, consists of a series of interconnected punched sheets. When the motor is in operation, the current in the stator generates a magnetic field that interacts with the magnetic field in the rotor, thereby generating a torque that causes the rotor to begin to rotate. However, when the rotor rotates, eddy currents are generated between the laminations, which cause rotor losses and heat generation. In order to reduce the generation and loss of eddy currents, magnetism isolating rings can be arranged between punching sheets of the rotor. The magnetism isolating ring is an annular part made of magnetic conductive materials, and can effectively prevent vortex from being generated, so that rotor loss and heat generation are reduced. In addition, the magnetism isolating ring can also reduce the magnetic leakage of the rotor and improve the efficiency and performance of the motor.
At present, lamination and compaction are needed to be carried out on punching sheets when the motor rotor is manufactured. During lamination, a positioning tool is usually required to perform axial concentric positioning on the rotor punching sheet, and pressurization fastening is performed. However, the lamination process is completed by taking out the rotor core and then assembling it to the rotor shaft. The assembly mode has the problems that on one hand, the assembly process is complex and complicated, and the production efficiency is low. On the other hand, after taking out the rotor core, the punching sheet group after being pressed and fastened by the tool is difficult to ensure that the punching sheet group is still tightly connected with the magnetism isolating ring after being taken out, and the circumferential alignment degree of the punching sheets at other positions is more difficult to ensure.
Therefore, how to ensure accurate and firm positioning of the laminated rotor punching sheet is an important technical problem and improvement point of the current rotor punching sheet lamination process. Meanwhile, how to ensure the circumferential alignment of the laminated rotor punching sheet and ensure the tight connection between the laminated rotor punching sheet and the magnetism isolating ring is also a technical problem to be solved.
