METHOD OF ASSEMBLING HIGH-SPEED ELECTRICAL MACHINE ROTOR |
摘要 |
FIELD: electricity. ^ SUBSTANCE: invention refers to the sphere of electrical engineering and electrical machinery industry and is of relevance for design and development of high-speed synchronous electrical machinery equipped with permanent magnets. Conceptually the invention consists in the process of the electrical machine rotor assembly envisaging an alternating pole magnetic system being mounted on the rotor shaft composed of tangentially magnetised permanent magnets (1) with the poles arranged between them. Under the method proposed the magnetic system consists of regularly alternating magnetic (2) and non-magnetic (3) O-plates with slots for insertion of permanent magnets (1). First the nonmagnetic plates (3) are fixed on the shaft being slipped on the axial pins (4) regularly alternating with the magnetic plates (3) whose outer diameter exceeds that of the magnetic plates. After that all the plates are tightly drawn together in the axial directions with the help of the remaining pins and the projecting edges of the magnetic pales (2) are turn-treated till the latter's outer diameter comes to equal that of the nonmagnetic plates (3); the treatment over, the permanent magnets are mounted. ^ EFFECT: facilitation of assembly and reduction of labour intensity. ^ 3 cl, 2 dwg |
