Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a toothed motor. Background Technology

[0002] Electric motors are widely used in power generation, drive applications, and other applications. They operate by utilizing the interaction of the magnetic fields of a rotor and a stator that rotate relative to each other. The stator consists of a stator core and stator windings. The stator windings are arranged around the teeth of the stator core and extend through the slots between the teeth to define different electrical phases.

[0003] For example, patent CN116961293A discloses a winding structure and winding method for a motor stator. It includes a stator frame, wires, and pins. The stator frame has an even number of winding teeth, and a coil is wound around each winding tooth via a wire. The coils on two opposing winding teeth are wound with the same wire to form a winding group. The pins are connected to the stator frame, with each pin corresponding to a winding tooth. The two ends of the wound wire are wound onto the pins. After the wire wraps around one winding tooth, it passes along the inner side of the stator frame, crisscrossing multiple spaced winding teeth, and then winds onto the opposing winding teeth.

[0004] The problem with the above technology is that the winding process of winding wires onto winding teeth is complex, time-consuming, inefficient, and results in low slot fill rate.

[0005] To address these technical problems, a toothed motor is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a toothed motor with high stator assembly production efficiency and high slot fill rate.

[0007] The technical solution adopted by this utility model to solve the problem is: a toothed motor, including a stator assembly, the stator assembly including a plurality of segmented stators arranged in a ring, an insulating frame sleeved on the segmented stator, at least one coil wound on the insulating frame, a ring terminal plate provided at the front end of the segmented stator, a heat shrink tubing without pressure ring provided on the ring terminal plate, and the end of the coil extending to the outside of the ring terminal plate and connected to the heat shrink tubing without pressure ring.

[0008] As a further improvement to the above technical solution, the system includes a housing, in which the stator assembly is fixedly disposed, and a rotor assembly is rotatably connected within the housing. The rotor assembly is located inside the stator assembly. The system also includes a motor shaft, the rear end of which is connected to the rotor assembly, and the front end of which extends to the outside of the housing.

[0009] As a further improvement to the above technical solution, the segmented stator includes a first transverse portion arranged in the front-back direction and a second transverse portion perpendicular to the first transverse portion. The cross-section of the segmented stator is T-shaped. The insulating frame is sleeved on the first transverse portion, and adjacent second transverse portions abut against each other.

[0010] As a further improvement to the above technical solution, the insulating frame includes a detachably connected upper frame and a lower frame, both of which are provided with winding grooves.

[0011] As a further improvement to the above technical solution, the left and right ends of the second horizontal portion are respectively provided with protrusions and grooves, and the protrusions on the second horizontal portion engage with the grooves on the adjacent second horizontal portion.

[0012] As a further improvement to the above technical solution, the rotor assembly includes a rotating disk with evenly distributed, spaced mounting slots on the rotating disk, a rotor being disposed in the mounting slots, a through slot being provided in the middle of the rotating disk, and the rear end of the motor shaft being fixedly disposed in the through slot.

[0013] As a further improvement to the above technical solution, an output shaft is provided at the front end of the motor shaft, and a guide groove is provided around the outer side of the output shaft.

[0014] As a further improvement to the above technical solution, a step is provided at the rear end of the motor shaft, and a first ball bearing and a second ball bearing are sleeved at the rear end of the motor shaft. The first ball bearing is located at the rear end of the step, and the second ball bearing is located at the front end of the step. A third ball bearing is sleeved at the front end of the motor shaft, and the third ball bearing is located at the rear end of the output shaft.

[0015] As a further improvement to the above technical solution, an oil seal and a flat bearing are fitted on the motor shaft, with the flat bearing located between the third ball bearing and the oil seal.

[0016] The beneficial effects of this utility model are: the stator assembly of the motor is composed of several segmented stators arranged in a ring. During installation, the segmented stators are first wound with coils and then assembled into a whole. Adjacent coils are connected by heat shrink tubing with solder without pressure rings. This results in high production efficiency, improves the slot fill factor of the segmented stators, and solves the problem of leaving space between slots for winding coils and the problem of empty slot fill factor.
