Novel efficient permanent-magnet synchronous motor and assembling method thereof

Abstract

The invention discloses a novel efficient permanent-magnet synchronous motor and an assembling method thereof. The novel efficient permanent-magnet synchronous motor comprises a casing, stator cores and a rotor assembly which are sequentially arranged from outside to inside, wherein the stator cores are uniformly arranged along an inner circle of the casing, an electromagnetic winding is arrangedin an inner groove of each stator core, each electromagnetic winding comprises two groups of vertical enameled wires arranged side by side, each of the upper and lower ends of each group of enameled wires penetrates through one coil separation block, the upper ends of the two groups of the enameled wires are jointly connected with an upper connecting seat, the lower ends of the two groups of the enameled wires are jointly connected with a lower connecting seat, enameled wire connecting conductors are arranged in the upper connecting seat and the lower connecting seat, and the two groups of enameled wires, the upper connecting seat and the lower connecting seat jointly form one complete loop. The defects that the production process is complicated, the groove full rate is low, maintenance isdifficult and the cost is high in the production process of the electromagnetic windings can be effectively overcome, and the overall performance of electronic products is improved.

Description

technical field [0001] The invention relates to the technical field of motors, and more specifically relates to a novel high-efficiency permanent magnet synchronous motor and an assembly method thereof.

Problems solved by technology

[0003] At present, electromagnetic products, especially permanent magnet motor products, have electromagnetic windings that are wound round by round. Whether it is a separate winding of a permanent magnet motor or the overall winding of a traditional permanent magnet motor, it is a major difficulty in the motor manufacturing process. Complex production process, low slot full rate, difficult post-maintenance, and high cost are almost inevitable pain points, which are one of the main barriers to performance improvement of electromagnetic products
