Abstract
The utility model relates to a full-automatic electric machine rotor punching sheet comprising a round punching sheet body, the center of the punching sheet body is provided with a rotating shaft hole which is 12.1 mm in diameter, the upper end of the rotating shaft hole is provided with a key groove which is a semicircle groove which is 1.5 mm in radius, six auxiliary holes that are 6 mm in diameter are annularly arranged at the outer side of the rotating shaft hole, 30 wire inserting grooves are annularly arranged at the outer sides of the auxiliary holes, two ends of each wire inserting groove are round holes, and one round hole facing toward the circle center of the punching sheet body is 1.6 mm in diameter while the other round hole facing toward the outer edge of the punching sheet body is 2.4 mm in diameter; one side, facing toward the outer edge of the punching sheet body, of each wire inserting groove is provided with an opening groove which is 0.8 mm in width and 0.6 mm in height; one side, neighboring the punching sheet body, of each opening groove is provided with a closed groove which is 0.12 mm in height. A rotor of the utility model is adjusted in punching sheet groove type. The full-automatic electric machine rotor punching sheet is advantageous in that electromagnetic performance of an electric machine adopting the design can be fully and reasonably used in the punching sheet, the electric machine is increased in moment of force, high electric energy conversion efficiency is realized, and material cost can be saved.
Description
Technical field
The utility model relates to electric motors, relates in particular to a kind of full-automatic motor rotor punching.
Background technology
Motor (Motors) is a kind of equipment that electric energy is converted to mechanical energy.It is to utilize hot-wire coil (namely stator winding) to produce rotating magnetic field and act on rotor (aluminium frame as closed in squirrel-cage) to form magnetoelectricity dynamic rotation moment of torsion.Motor, by using power supply difference to be divided into DC motor and alternating current motor, can be synchronous machine or asynchronous machine (motor stator rotational speed of magnetic field and rotor rotating speed do not keep synchronous speed).Motor is mainly made up of stator and rotor, and the direction of electrified wire stressed motion in magnetic field is relevant with magnetic induction line (magnetic direction) direction with the sense of current.Motor operation principle be magnetic field to the stressed effect of electric current, make motor rotate.Rotor is the part that motor rotates, under the Main Function excitation effect of rotor, rotate, rotor rotates, be mechanical energy by electric energy conversion, in the time of the production and application of rotor, need to consider the utilization rate of its transformation efficiency and material, higher than general motor in the rotor punching requirement for full-automatic laundry machine motor, therefore need to design more satisfactory rotor punching.
Summary of the invention
For dealing with problems, the utility model provides that a kind of motor torque increases, electric energy conversion efficiency is high, and can save a kind of full-automatic motor rotor punching of material cost.
The technical scheme in the invention for solving the technical problem is: a kind of full-automatic motor rotor punching, comprise punching body, described punching body is circular punching, the center of described punching body offers shaft hole, the diameter of described shaft hole is 12.1mm, the upper end of described shaft hole offers keyway, described keyway is that radius is 1.5 semi-circular groove, the exterior annular of described shaft hole is placed with the via hole that six diameters are 6mm, described via hole exterior annular is placed with 30 line embedding grooves, the two ends of described line embedding groove are that circular port and circular port are being 1.6mm towards the diameter in the punching body center of circle, be 2.4mm towards the diameter of punching body outer rim, described line embedding groove is also to offer 0.8mm towards punching body outer rim one side wide, 0.6mm high open slot, offer the high closed slot for 0.12mm in a side adjacent with punching body of described open slot.
Further, the junction of described open slot and line embedding groove offers chamfering.
Further, the distance at described line embedding groove two ends is 5.9mm.
The beneficial effects of the utility model: rotor of the present utility model, its punching grooved is adjusted, and advantage is to adopt the motor electromagnetic performance of this kind of design to be used adequately reasonably in punching, and motor torque is increased, electric energy conversion efficiency is high, and can save material cost.
