Abstract

The invention relates to a rotor, a whole pole module assembling method of the rotor, a replacement method and a motor. The rotor is arranged on the outer peripheral surface of a motor stator in a sleeved mode, and comprises a rotor magnetic yoke, a plurality of pressing strips, a plurality of whole pole modules, and a plurality of fixed parts, wherein the rotor magnetic yoke is provided with an opposite mounting surface and outer peripheral surface in the radial direction; the plurality of pressing strips are distributed on the mounting surface at intervals along the circumferential directionof the rotor magnetic yoke, and the radial distance between each pressing strip and the mounting surface is adjustable; each whole pole module is detachably connected between every two adjacent pressing strips; the whole pole module comprises a carrier plate and a plurality of permanent magnets arranged on the carrier plate, wherein the carrier plate is attached to the mounting surface; each pressing strip is mounted on the mounting surface through the fixed part; and each fixed part has an operation part capable of extending from the outer peripheral surface. According to the invention, thewhole pole module formed by a plurality of permanent magnets can be integrally assembled or disassembled, and the whole pole module can be replaced without disassembling the motor stator and the rotor, so that the maintenance cost of the motor rotor is lowered.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a rotor, a method for assembling a complete pole module of the rotor, a replacement method and a motor. Background technique [0002] The direct drive permanent magnet generator usually adopts the structure of outer rotor and inner stator. The rotor includes a rotor yoke and a magnetized permanent magnet fixed to the rotor yoke. [0003] In large-scale generators such as wind turbines, the rotor is generally provided with an alternating magnetic field by multiple rows of whole-pole modules. Each row of whole-pole modules is composed of multiple permanent magnets or multiple magnetic pole modules, and the same assembly process needs to be repeated The magnets or pole modules are assembled to the rotor yoke one by one, and the assembly process is complicated. [0004] In addition, the air gap formed between the rotor and the stator is usually on the order of millime...
