Abstract
The utility model relates to the motor technology field and discloses a motor rotor punching sheet comprising a punching sheet body and punching sheet grooves, wherein the punching sheet groove is a V-shaped opening-shrinking structure. The amount of the punching sheet grooves is 22. The bottom of the punching sheet grooves is a fillet. Fillet radius is 1.06 mm. The V-shaped opening-shrinking structure comprises shoulders and a neck. Width of the shoulders is 4.43 mm, height of the shoulders is 0.3 mm, width of the neck is 2.2 mm and height of the neck is 1 mm. The motor rotor punching sheet provided by the utility model cannot change an original assembling mode of the motor and is directly used instead of an original motor punching sheet, so that work efficiency of the motor is raised. When the motor using the rotor punching sheet is in an operation state, electromagnetic noise is small, starting current is small and torque is large.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of motor rotor punching slice.
Background technology
Along with development and national economy, energy problem has more and more obtained people's attention, develops energy-efficient motor product, is key subjects of machine field, and motor rotor punching sheet is directly connected to the quality of motor.Be widely used in the motor of basic activities such as industry, agricultural, commerce, building industry at present, defective such as ubiquity efficient is low, energy consumption is big.
Rotor punching is the critical component in the motor, and its material, interior round size, excircle dimension, flute profile quantity and size shape have direct influence to efficiency of motor.Using maximum in the market is the Y2 serial motors, finds to exist shortcomings such as electromagnetic noise is big, starting current is big, torque is little in its long-term use.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of motor rotor punching slice to be provided, in the hope of using the motor energy-conservation of consumption reduction of this punching.
The technical scheme that the utility model is taked is:
A kind of motor rotor punching slice comprises punching body and punching groove, it is characterized in that, described punching groove is a V word closing in type structure, and the quantity of described punching groove is 22, and the bottom of described punching groove is a fillet.
Further, described radius of corner is 1.06mm, and described V word closing in type structure comprises shoulder and neck, and the width of described shoulder is 4.43mm, and the height of described shoulder is 0.3mm, and the width of described neck is 2.2mm, and the height of described neck is 1mm.
Further, the deviation of described neck height is 0 to 0.02mm.
Further, in the middle of the described punching body is a circular hole, the center of circle of the fillet of described 22 punching grooves surrounds an inner periphery, the coaxiality error maximum of described inner periphery and described circular hole is 0.04mm on the diametric(al), the outermost border of described 22 punching grooves surrounds an excircle, and the coaxiality error maximum of described excircle and described circular hole is 0.03mm on the diametric(al).
Further, the diameter of described circular hole is 10mm, and deviation is 0.04mm to 0.06mm, and the diameter of described inner periphery is 28.04mm, and deviation is-0.01mm to 0.01mm, and the diameter of described excircle is 47mm, and deviation is-0.01mm to 0.01mm.
The beneficial effects of the utility model are:
Need not change original fit of motor, directly replace the punching of original motor, improve the operating efficiency of motor with this rotor punching;
When using the machine operation of this rotor punching, electromagnetic noise is little, and starting current is little, and torque is big.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is partial enlarged drawings of a punching groove in the accompanying drawing 1.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model motor rotor punching slice.
Referring to accompanying drawing 1, motor rotor punching slice comprises punching body 1 and punching groove 2, and punching groove 2 is a V word closing in type structure, and the quantity of punching groove 2 is 22.The bottom of punching groove 2 is a fillet, has circular hole in the middle of the punching body 1, and Circularhole diameter is that the diameter of circular hole is 10mm, and its machining deviation scope is 0.04mm to 0.06mm.The center of circle of the fillet of 22 punching grooves surrounds an inner periphery, and the diameter of inner periphery is 28.04mm, and deviation is-0.01mm to 0.01mm.The outermost border of 22 punching grooves surrounds an excircle, and the diameter of excircle is 47mm, and deviation is-0.01mm to 0.01mm.The coaxiality error maximum of inner periphery and circular hole is 0.04mm on the diametric(al), and the coaxiality error maximum of excircle and described circular hole is 0.03mm on the diametric(al).Distance between two punching groove 2 adjacent dual-sides is 1.9mm, and deviation is-0.01mm to 0.01mm.Place, the exterior angle rounding that V-shape closes up, radius of corner 0.06mm.
Referring to accompanying drawing 2, the bottom radius of corner of punching groove 2 is 1.06mm.V word closing in type structure comprises shoulder and neck, and the width of shoulder is 4.43mm, and the height of shoulder is 0.3mm, and the width of neck is 2.2mm, and the height of neck is 1mm, and the deviation of neck height is 0 to 0.02mm.Shoulder lower end and V-shape side joint rounding, radius of corner 0.3mm.
The burr of whole rotor punching can not surpass 0.04mm.The flute profile tolerance is pressed IT10 processing.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
