Rotary motor stator assembly

The present invention relates to a motor assembly, and more particularly to a rotating electrical machine stator assembly.

With the advancement of technology, the demand for the use of electric motors (also known as motors) is increasing. Its main function is to convert electrical energy into mechanical energy, and then use mechanical energy to generate kinetic energy to drive other devices. Most of the motors generate energy in the motor through the magnetic field and current. The main structure consists of a ring stator and a rotor. The rotor and the rotor are wound around the ring stator by rotating the rotor in the ring stator. The magnetic fields interact to generate power.

Conventionally, the winding method of the stator of the motor is mostly formed by stacking a plurality of enameled wires in the grooves of the stator to form a whole series of coil groups. Therefore, the manufacturing process is very complicated and requires a lot of man-hours. In the winding process, the plurality of enameled wires are easily rubbed against each other to cause insulation quality. In addition, since the plurality of enameled wires are stacked one on another into a series of coil groups, gaps are easily generated between the enameled wires. Will affect the efficiency of motor operation.

In view of the above problems, the present invention provides a rotating electrical machine stator assembly comprising an annular body and a plurality of wires. The annular body includes an upper side, a lower side, The inner ring surface and the plurality of groove teeth, the plurality of groove teeth are arranged on the inner ring surface and extend radially inward, wherein the plurality of groove teeth form 48 through grooves in sequence, and each of the through grooves is divided into an outer area and an inner side area. The width of each of the wires is slightly smaller than the groove width of each of the through slots, and the plurality of wires are respectively wound in the plurality of slots, and the outer and inner regions of each of the slots are respectively embedded with a wire, and each of the wires is waved and includes a bent portion, a lower bent portion and a plurality of straight portions, the upper bent portion is located on the upper side of the annular body and includes two upper through-groove ends, the lower bent portion is located on the lower side of the annular body and includes two lower through grooves The end, the plurality of straight portions are respectively located in the plurality of slots and are coupled to the upper bent portion and the lower bent portion. Wherein, a portion of the lower lower portion of the bent portion is spaced by 10 slots, and a portion of the lower bent portion is spaced apart by 11 slots, so that each of the upper sides is located There are 11 slots between the two upper slot ends of the upper bent portion, and the two upper slot ends of the upper bent portions are respectively located in the outer and inner regions.

With the above structural design, the stator assembly of the rotating electrical machine can be first bent into two U-shaped shapes of different widths in the manufacturing process, that is, the plurality of wires can be bent through the machine to form the above. a lower bent portion and two straight portions connected to the lower end of the lower bent portion, and the distance between the two lower through-groove ends of the partial U-shaped wire and the two straight portions are spaced by 10 slots to correspond to the ring shape The lower side of the body is inserted into a predetermined position. The distance between the two lower through-groove ends of the remaining U-shaped wires and the two straight portions is 11 slots, so as to be correspondingly inserted into the predetermined position by the lower side of the annular body. Thereby, the plurality of straight portions can be passed out of the upper side of the annular body, and the adjacent straight portions of the two adjacent U-shaped wires are separated by a distance of 11 slots. Since the adjacent straight portions of two adjacent U-shaped wires are separated by the same distance, they can be directly transmitted through the machine. The device automatically bends the adjacent straight portions into a distance of 11 slots and welds them to each other (such as by ultrasonic welding or arc welding) so that the U-shaped wires are connected to each other and form the above-mentioned plurality of upper bent portions. Achieving a drastic reduction in the complexity of the winding operation, making the rotating machine stator assembly more automated in manufacturing and improving production efficiency.
