Abstract

The invention discloses a motor stator connecting piece based on a circumferential step-shaped circular ring, which belongs to the technical field of motor assembly, and is characterized in that a stator core excircle comprises N steps, N is an even number greater than or equal to 2, the diameters of the stator core excircles at the steps are different, and the stator core is of a radial symmetric structure; the inner circle of the casing is in a step shape matched with the outer circle of the stator iron core, and the diameter of the inner circle of the casing is matched with that of the outer circle of the iron core. When the number of the symmetry axis of the stator iron core is one, N is equal to 2, 4, 6, 8,..., and at the moment, the diameters of the outer circles of the stator iron core are 2, 3, 4, 5,...; when the number of symmetry axes of the stator core is two, N is equal to 4, 8, 12, 16,..., and at the moment, the diameters of the outer circles of the stator core are 2, 3, 4, 5,.... The motor stator yoke is used for motor assembly, and solves the problem that the motor performance is affected due to the fact that mechanical connection between the existing motor stator yoke and the motor shell is achieved through a key groove structure.

Description

technical field [0001] The invention belongs to the technical field of motor assembly, and relates to a motor stator connector based on a circumferential stepped ring. Background technique [0002] The stator yoke of the motor is an important part connecting the motor armature and the casing. In the design process, in addition to the electromagnetic problems such as the magnetic circuit, the mechanical assembly of the motor must also be considered. The design of the stator yoke is not only easy to assemble, but also to ensure that the stator core of the motor can be mechanically connected to the casing reliably, and no offset will occur during the operation of the motor. Otherwise, in the long-term operation process, the stator is likely to be deformed due to uneven force, which affects the running performance of the motor. In severe cases, the stator and rotor may even be swept, causing major accidents. [0003] At present, the mechanical connection between the motor stato...
