Abstract

The invention provides a magnetic pole installing device for a surface-mounted permanent magnet motor. The magnetic pole installing device comprises a locating mechanism (10) locating and fixing a rotor core (5), an indexing mechanism (1) driving the rotor core (5) to rotate and setting the angle, a guide mechanism (6) holding magnetic poles (4) and aligning the magnetic poles (4) and magnetic pole grooves of the rotor core (5), and a power pushing mechanism (7) pushing the magnetic poles (4) to install the magnetic poles in the magnetic pole grooves. The indexing mechanism (1) and the rotor core (5) rotate in linkage. The magnetic pole installing device effectively solves such problems as great difficulty in surface-mounted permanent magnet motor magnetic pole installing and low surface-mounted permanent magnet motor magnetic pole installing accuracy.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a magnetic pole installation device of a surface-mounted permanent magnet motor. Background technique [0002] Permanent magnet motors are the direction of motor development in the future. At present, permanent magnet motors have been involved in aerospace, rail transit, precision measurement and other fields. Magnetic rotor manufacturing technology is the key manufacturing technology of permanent magnet motors, especially for surface-mounted permanent magnet motors, which require higher reliability of magnetic pole fixing. [0003] The surface-mounted magnetic pole structure is different from the embedded magnetic pole structure. The magnetic pole assembly of the surface-mounted magnetic pole structure is more difficult. The permanent magnets in the surface-mounted permanent magnet motor are usually fixed by sticking, binding or a combination of the two methods. The pasting-type...
