Magnetic-steel sticking device for rotor of permanent-magnet motor

Abstract

The invention discloses a magnetic-steel sticking device for a rotor of a permanent-magnet motor. The magnetic-steel sticking device comprises a magnetic-steel baffle plate, a plurality of magnetic-pole partitioning plates, a guiding drum, a pressing plate and a fixed ring, wherein the magnetic-steel baffle plate sheaths one end of the magnetic-steel installing section of a rotary shaft of the motor; the plurality of magnetic-pole partitioning plates are arranged on the outer circle of the rotary shaft of the motor to form a plurality of magnetic-steel installing grooves; the guiding drum is arranged at the other end of the magnetic-steel installing section of the rotary shaft of the motor, and a plurality of guiding grooves are formed in the outer circle of the guiding drum; the pressingplate is provided with a pushing mechanism for driving magnetic steel to do axial movement; the fixed ring can be axially adjusted for movement and is internally provided with a plurality of pressingblocks, and a pressing mechanism for driving the pressing blocks to do radial movement is arranged on the fixed ring. The magnetic-steel sticking device disclosed by the invention has the advantages that the structure is simple, and the manufacturing cost is low; the operation is convenient, and the assembling efficiency is improved; the damage risk of the magnetic-steel material is reduced; the risk of industrial injuries of workers is reduced; the magnetic-steel glue is uniformly pressed, so that the sticking effect is good.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a permanent magnet motor rotor magnetic steel pasting device. Background technique [0002] The magnetic steel structure pasted on the surface of the rotor is one of the most commonly used structures of permanent magnet synchronous motors. The traditional rotor surface-mounted magnetic steel is manually pasted. For high-speed and high-power permanent magnet synchronous motors, the permanent magnets pasted on the rotor surface are generally larger. , the suction force between the magnetic steel and the rotor core is very large, and the repulsive force between the permanent magnet and the same pole of the permanent magnet is also very large. The magnetic steel is a powder metallurgy material containing rare earth elements, which is fragile and expensive, and the production cycle is long. .

[0002] The magnetic steel structure pasted on the surface of the rotor is one of the most commonly used structures of permanent magnet synchronous motors. The traditional rotor surface-mounted magnetic steel is manually pasted. For high-speed and high-power permanent magnet synchronous motors, the permanent magnets pasted on the rotor surface are generally larger. , the suction force between the magnetic steel and the rotor core is very large, and the repulsive force between the permanent magnet and the same pole of the permanent magnet is also very large. The magnetic steel is a powder metallurgy material containing rare earth elements, which is fragile and expensive, and the production cycle is long.

In the assembly process of large surface-mounted magnetic steel, manual assembly will not only fail to install it in place, but also cause damage to the magnetic steel and the risk of worker injury
