Abstract

The invention provides a motor rotor silicon steel sheet for improving structural strength, which includes: an annular sheet body; a central hole formed through the annular sheet body; and a plurality of hollow elements formed through the annular sheet body, arranged It is a circle and surrounds the periphery of the central hole. Each hollow element has an inverted trapezoidal hollow, two side separating ribs, a central rib, two outer supporting oblique ribs and two inner supporting oblique ribs, wherein the central rib, the two outer The supporting oblique ribs and the two inner supporting oblique ribs together present a roughly *-shaped structure. The silicon steel sheet of the motor rotor can improve the structural strength and reduce the rotational inertia through the configuration of hollow elements.

Description

technical field [0001] The present invention relates to a motor, especially a silicon steel sheet of a motor rotor with improved structural strength, which can increase its structural strength and reduce its own weight, and avoid the problems of reduced structural strength and excessive rotational inertia of the rotor containing the silicon steel sheet. Background technique [0002] Induction motors are generally used in most electrical products, and have a stator, a rotor and a plurality of silicon steel sheets, the stator has a plurality of silicon steel sheets, and the rotor also has a plurality of silicon steel sheets. The principle of the induction motor is that when the current flows through the stator silicon steel sheet, the stator silicon steel sheet will generate a rotating electromagnetic field, and this electromagnetic field will also cause the induction rod inside the rotor to generate current in the axial direction, and this current will be generated with the en...
