Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description: referring to fig. 1-5, in a limit structure of a rotor coil, a plurality of groups of coils are generally wound on a rotor 1 to form a winding, so that a groove 9 is required to be provided on the rotor 1.
In this embodiment, the rotor 1 comprises 12 sets of grooves 9, so that in general, the coils are wound in the grooves 9, i.e. there are several sets of coils wound between the two sides of the rotor 1, the sets of coils form the windings of the rotor 1, and the number of coils is indicated in the grooves 9 by the slot filling rate, the more coils in the same groove 9, the higher the slot filling rate.
The two sides of the rotor 1 are provided with end plates 2, two end plates 2 are matched with grooves 9, each end plate 2 comprises a plurality of claw rods 3, each claw rod 3 is formed by outwards extending end plates, meanwhile, the number of the claw rods 3 is the same as that of the grooves, namely, the number of the claw rods 3 is 12, and further, coils need to be wound through the claw rods 3.
The claw rod 3 is circumferentially distributed on the end plate 2, and is circumferentially equidistant, a hole matched with and used for installing the rotor shaft 10 is formed in the center of the end plate 2, and after the end plate 2 is sleeved on the rotor shaft 10, the claw rod can be matched with the groove to install a coil.
When the slot filling rate in the slot 9 is higher, i.e. the more coils are in the slot 9, the number of coils placed at the bottom of the rotor 1 becomes larger, the coils are easily separated from the end plate 2, the coils are off-line, the motor installation efficiency is low, and the yield is reduced.
Therefore, the lug 4 is arranged on the claw rod 3, the lug 4 is used for limiting the coil, further, two sides of the lug 4 are smaller than the length of the claw rod 3, the lug 4 is vertically arranged on the claw rod 3, one side of the lug 4 is gradually increased towards the coil, namely, the lug 4 is arranged towards one side far away from the rotor shaft 10.
Therefore, when the coil winding gradually increases, the lug 4 can clamp part of the coil between the two coils to realize the effect of winding more coils, meanwhile, the lug 4 with proper length can not influence the effect of the end plate 2, under the rotor 1 with the same volume, the end plate 2 with the lug 4 can wind more coils, namely, the moderate increase of the slot filling rate is realized, the power of the motor is improved, and meanwhile, the rotor 1 with the moderate high slot filling rate can improve the service life of the motor.
One side of the rotor 1 is provided with a commutator 5, the commutator 5 is connected with each group of coils, and the commutator 5 plays a role in commutation when being used for motor rotation and is a component for enabling the motor to continuously rotate. Meanwhile, the fan 6 is arranged on the other side of the rotor 1, when the rotor 1 rotates in the motor, the fan 6 rotates to form air flow to blow to the coil, and the temperature of the coil can be higher under the condition of electrifying, so that the air flow can realize coil cooling.
The insulation paper 8 is arranged in the groove 9, the insulation paper 8 separates the coil from the groove 9, meanwhile, the groove 9 is internally provided with the slot wedge 7 in an inserted mode, the slot wedge 7 is used for clamping the coil, the coil is stably arranged in the groove 9, single wire of the coil can be effectively prevented from falling off, and the service time of the motor is shortened. After the lug 4 with the limiting function, the production efficiency of the high-slot full rate rotor 1 can be improved, and meanwhile, the coil off-line rate of the lug 4 is reduced, so that breakdown can be reduced in the process and the yield can be improved when the slot wedge 7 is automatically inserted in the subsequent process.
