A frameless motor stator rotor structure and a frameless motor

Abstract

The utility model belongs to permanent magnet motor technical field, concretely relates to a frameless motor stator rotor structure and a frameless motor, including modularization stator and sectional skew pole rotor, modularization stator includes tooth part and yoke part, tooth part is provided with at least one, and is provided with at least one insertion block on tooth part, the inner surface of yoke part is along the circumferential interval and is provided with insertion slot, and the number of insertion slot is equal with the number of insertion block of tooth part, the insertion block of each tooth part is sequentially inserted and is fitted in the insertion slot of yoke part, makes tooth part and yoke part constitute modularization stator, sectional skew pole rotor adopts axial sectional skew pole structure. Compared with prior art, the utility model solves the problem of prior art that although skew pole structure can reduce tooth slot torque to a certain extent, but still has the problems of complex process and high cost. The scheme realizes the reduction of manufacturing difficulty, manufacturing cost and maintenance cost by simultaneously implementing structure improvement to stator structure and rotor structure, and further reduces tooth slot torque.
