Description

Technical Field

[0001] The utility model belongs to the field of motors, in particular to a combined motor stator structure. Background Art

[0002] The stator is the stationary part, opposite to the rotor. In an AC motor, the stator usually contains a stator core with coils wound around it. These coils will generate a rotating magnetic field when connected to an AC power source. This rotating magnetic field will shear the conductor on the rotor, and through the principle of electromagnetic induction, an induced current will be generated on the rotor, thereby forming an induced magnetic field. The interaction of the two magnetic fields will cause the rotor to rotate, thereby realizing the conversion of electrical energy into mechanical energy.

[0003] The stator is usually made of multiple stacked laminations, which are generally made of silicon steel. The stacked silicon steel sheets are fixed together by welding, hot pressing, etc. to form the stator core. In order to reduce eddy current losses, each silicon steel sheet is usually insulated.

[0004] After the laminations are stacked, winding protrusions are formed on the inner ring, and winding grooves are formed between the winding protrusions. After the wires are wound on the winding grooves, there will be wire protrusions in front and behind the stator because the wires need to be connected. Figure 5 As shown, the housing and the stator are connected through a base, which is used to fix the stator. After fixation, the protruding wires are completely exposed inside the housing. Under this premise, since the motor will generate vibration when it is running, the exposed wires will cause them to deform under the influence of long-term vibration. Utility Model Content

[0007] Furthermore, the fixing mechanism includes connecting holes that penetrate through each ear plate, and each set of upper and lower connecting holes are matched and connected with a combination bolt.

[0008] Furthermore, the combination bolt consists of a head, a threaded rod and a nut. The upper connecting hole is divided into an upper-upper hole and an upper-lower hole. The upper-upper hole is used to accommodate the head, and the upper-lower hole is used to pass through the rod; the lower connecting hole is divided into a lower-lower hole and a lower-upper hole.
