Abstract
The utility model relates to a rotor punching sheet with axial air vents, belonging to the field of motors. The rotor punching sheet comprises a rotor punching sheet body, an installation hole is formed in the rotating center of the rotor punching sheet body, 62 punching sheet grooves are uniformly arranged in the outer periphery of the rotor punching sheet body, and the multiple air vents are uniformly arranged in the rotor punching sheet body over the installation hole. According to the utility model, a stamping die for the rotor punching sheet is changed and the rotor punching sheet body is punched on a punch via silicon steel plates instead of changing the original assembling manner for the motor; and thus, the rotor punching sheet is equipped with the axial air vents, heat in the motor can be better circulated, and the heat can be taken away as soon as possible.
Description
Technical field
The utility model belongs to electric motors, is specially a kind of rotor punching with axial ventilation hole.
Background technology
Motor is a kind of equipment that converts electric energy to mechanical energy, inevitably produce power loss in transfer process, and energy loss will produce a large amount of heats.Under the energy of advocating thriftiness energetically now, protection of the environment, energy-efficient overall background, in order to improve the utilance of material in motor, modern age, motor all adopted higher electromagnetic load, and single-machine capacity is improved as far as possible.And will certainly produce larger loss when improving the electromagnetic load of motor and single-machine capacity, also will produce more heat.
In order to improve the heat-sinking capability of threephase asynchronous, most motors of use are all to adopt external fan forced air to flow cooling motor now, and external refrigeration is just delivered to motor internal the heat of motor outer surface, by convection current or radiation, heat is fallen apart in ambient gas.But the thermal source of motor, the namely winding in motor internal and the unshakable in one's determination heat producing, but cannot very fast distributing, and can only be conducted heat is delivered to outside motor at leisure by heat.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, ingenious, reasonably with the rotor punching of axial ventilation hole, this rotor punching can leave motor internal winding and the heat producing unshakable in one's determination fast.
The technical scheme providing according to the utility model: a kind of rotor punching with axial ventilation hole, be characterised in that: comprise rotor punching body, the described rotor punching body centre of gyration offers installing hole, rotor punching body outer circumference surface is uniform arranges 62 punching grooves, and the top corresponding to installing hole on described rotor punching body has also been evenly arranged some ventilation holes.
As further improvement of the utility model, described each ventilation hole is circular hole, and the center of circle of circular hole is distributed on the circumference that diameter phi d2 is 170mm, and Circularhole diameter φ d1 is 26mm.
As further improvement of the utility model, described in each, punching groove includes groove top ends, bottom land base portion and connects the cell body pars intermedia of described groove top ends and bottom land base portion; The slot opening br1 of described groove top ends is 1.5mm, and the long g of air gap is 1.1mm, and the high hr0 of notch is 0.5mm; Cell body pars intermedia bottom width br2 is 3.6mm, and height hr12 is 12mm; Cell body base portion upper end groove width br3 is 7mm, and bottom groove width br4 is 4mm, and the height hr3 of cell body base portion is 30mm.
[0009]the utility model compared with prior art, advantage is: the utility model need not change the intrinsic assembling mode of original motor, only need to change the diel of rotor punching, with silicon steel sheet, on punch press, go out rotor punching body, make rotor punching with axial ventilation hole, so that the heat of motor internal can better circulate, fast as far as possible goes out dissipation of heat.
