Abstract
The utility model discloses a motor rotor punched sheet. The entire rotor punched sheet is circular. The rotor punched sheet includes a circular punched sheet body; a plurality of tooth slots used for winding a stator coil are evenly distributed at the periphery of the punched sheet body; tooth portions are formed between the tooth slots; the radius of the entire rotor punched sheet is in a range of 15 to 17 mm; the radius of the punched sheet body is in a range of 7 to 9 mm; an upper half circular arc groove and a lower half circular arc groove are connected with each other to the tooth slot; the radius of the upper half circular arc groove is in a range of 1.9 to 2.1 mm; and 13 tooth slots are distributed at the periphery of the punched sheet body. According to the motor rotor punched sheet of the utility model, the size and shape of the rotor punched sheet are reasonably designed; the size and shape of the slots are reasonably designed, such that the area of the rotor tooth slots is increased, and more copper wires can be embedded in the tooth slots; and therefore, the improvement of motor efficiency can be facilitated, and energy saving effect can be improved; and at the same time, used materials can be reduced.
Description
Technical field
The utility model relates to motor, particularly a kind of motor rotor punching sheet.
Background technology
The slot size of the winding around that arranges in the motor rotor punching sheet is reasonable inadequately at present, and reasonable inadequately with punching body dimension design collocation, the punching size is bigger, and teeth groove quantity is more, has improved manufacturing cost, also is unfavorable for the motor energy efficient.
The utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, provides a kind of teeth groove flute profile reasonable in design, improves the motor rotor punching sheet of electric efficiency and energy-saving effect.
The utility model realizes that the technical scheme of above-mentioned purpose is:
A kind of motor rotor punching sheet, described rotor punching integral body is rounded, described rotor punching comprises circular punching body, periphery at the punching background is evenly distributed with several in order to twine the teeth groove of stator coil, form tooth portion between teeth groove and the teeth groove, the radius of rotor punching integral body is 15 ~ 17mm, the radius of punching body is 7 ~ 9mm, described teeth groove is to be connected to form by first groove and two arc grooves of second groove, the radius of described first groove is 1.9 ~ 2.1mm, in the peripheral distribution of punching body 13 teeth groove is arranged.
As preferably, the radius of rotor punching integral body is 16mm, and the radius of punching body is 8mm, and the radius of first groove is 2.0mm.
The beneficial effects of the utility model are: rotor punching has passed through the appropriate design to size, shape, because flute profile size, shape are reasonable in design, amplified the area of stator teeth groove flute profile, can embed more copper cash, be conducive to improve electric efficiency, thereby improve energy-saving effect, the size of having dwindled product, reduce the use of material, saved the use of material.
