Description

Sectional stator core

Technical Field

The utility model relates to the field of stator cores, in particular to a block type stator core.

Background

The stator core is an important component of the magnetic circuit of the motor, and forms a complete magnetic circuit of the motor together with the rotor core and the air gap between the stator and the rotor. In an asynchronous motor, the magnetic flux in the stator core is alternating, thus generating core losses. The core loss includes two parts: hysteresis loss and eddy current loss.

Through searching, the block type stator core (authorized bulletin number: CN 202495815 u) comprises a plurality of unit stator cores assembled into a ring shape, and further comprises a fixed ring, wherein each unit stator core is provided with a plurality of rivet holes matched with the fixed ring, and the fixed ring and the plurality of unit stator cores are fixed through rivets. The segmented stator core can save materials and effectively improve the material utilization rate.

According to the above related art, the inventor believes that the conventional stator core manufacturing method is generally integrated, and is formed by one-time stamping, and a whole block is required for stamping, and blanking of the stator core portion after the stamping is completed becomes waste material, resulting in waste of material and low material utilization rate.
