Abstract

The invention relates to a detachable motor rotor structure and a designing method thereof. Compared with the prior art, the detachable motor rotor structure solves the problem that the magnetizing isolation bridge of an existing motor rotor structure is easily broken and the rotor cannot be disassembled as a whole. In the invention, the outer surface of the rotor outer ring is provided with a plurality of grooves which are parallel to the axial direction of the rotor outer ring. The joints of the grooves and two ends of the rotor outer ring are provided with notches, two ends of the rotor inner ring are provided with recesses, the positions of the recesses are corresponding to the notches, and magnetic blocks are arranged between the rotor inner and outer rings and between the adjacent grooves. The detachable motor rotor structure eliminates the design of the magnetizing isolation bridge and enables the motor rotor structure to be detachably mounted.

Description

technical field [0001] The invention relates to the technical field of motor rotors, in particular to a detachable motor rotor structure and a design method thereof. Background technique [0002] Under the double pressure of "environmental pollution" and "energy crisis", the development of energy-saving and environment-friendly new energy vehicles has become the future development direction of the world's automobile industry. As a key component of new energy vehicles, motor is one of the core technologies to promote the development of new energy vehicles. With the development of motor technology, high-speed, high-performance motors have become the focus of attention. [0003] At present, the structure of the motor rotor of new energy vehicles is mainly composed of silicon steel sheets, magnetic steel, rotating shafts, pressure plates and other components. Both ends are fixed by pressing plates. [0004] There are following deficiencies in this structure and installation m...
