Abstract

The invention discloses a slip fit type rotor structure of a motor. The rotor structure comprises an integrally formed rotor body, a plurality of rotor slots are arranged on the outer circumference of the rotor body longitudinally and evenly, battens are installed at two inner side edges of each slot opening to enable the rotor slot space for accommodating a winding to form an inverted T shape, at least two transverse first trapezoid slots are arranged on each batten, second trapezoid slots are arranged on the inner wall of the rotor body corresponding to the positions of the first trapezoid slots, the length of the top edge of each first trapezoid slot is equal to that of the bottom edge of each second trapezoid slot, first trapezoid blocks and second trapezoid blocks which are integrally formed are arranged in the first and second trapezoid slots, and a rectangular groove with the width equal to that of the bottom edge of each first trapezoid slot is arranged on the outer side of each first trapezoid slot. The rotor structure solves the problem of slipping of the winding and can enable the winding stability of the motor to be good.

Description

technical field [0001] The invention is a slip-fit ​​motor rotor structure. Background technique [0002] The slot structure of the rotor often adopts a square structure. Due to the poor stability of the square structure, the windings in the slot are easy to fall off, resulting in unstable operation of the motor. Contents of the invention [0003] The purpose of the present invention is to provide a slip-fit ​​motor rotor structure to solve the problem of winding slippage. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] A slip-fit ​​motor rotor structure, including a rotor body, the rotor body is integrally formed, a number of rotor slots arranged longitudinally and uniformly are arranged on the outer circumference of the rotor body, and beading bars are respectively installed on the two outer sides of the slots so that the space for the rotor slots to accommodate the windings forms a "convex" sha...
