Description
Technical field
The utility model relates to a kind of Novel motor stator, belongs to technical field of motors.
Background technology
Stator is the actionless part of motor, and it is relative with rotor.Stator is primarily of the composition such as stator core, stator winding.The Main Function of stator produces rotating magnetic field, and the Main Function of rotor is by magnetic force line cutting and then generation (output) electric current in rotating magnetic field.The quality of stator, the parameters index primarily of stator core determines.At present, existing stator has the following disadvantages: first, the stator core stamping sheet forming stator core is tightened to an entirety by securing members such as screw, bolt, latches, need in punching the installation site of the securing member such as stamping-out screw, bolt, latch, cause the magnetic property of stator core to decline, loss is high, installs and takes up room greatly, make the corresponding increase of the volume of complete machine, the needs of motor miniaturization can not be met; The second, the measure of stator core coil groove naked, insulating properties is poor, and the end face of ground stator core adopts spray applied insulation to insulate, and coating thickness is uneven, and coating thin location insulation effect is undesirable; 3rd, stator core coil groove is in " O " font closed state or in " U " font open state, and during threading, " O " font closed state needs down to wear around iron core from the top of iron core, and winding efficiency is very low; After coiling, the lead-out wire of enamelled wire is around the periphery of mandrel bottom, be easy to cause enamelled wire to damage in motor installation process, enamelled wire after breakage contacts with iron core, the generation of the phenomenon such as cause that motor punctures, thus reduce the useful life of motor, and also this enclosed construction causes coiling amount less, iron core winding utilance with size is on the low side, and power is little; " U " font open state, coiling is under long-term vibration condition, and easy landing goes out outside groove to cause motor failure to work.
Utility model content
For the above-mentioned defect existed in prior art, the utility model aims to provide a kind of magnetic conductivity and good insulation preformance, easy for installation, winding efficiency is high, the Novel motor stator of long service life.
To achieve these goals, the utility model is by the following technical solutions: comprise stator core, the winding be wrapped on stator core, and be connected to the sleeve pipe of stator core side, described stator core to be pressed by fastening sheet fastening by some stator core stamping sheets and forms, its end face is bonded with insulating end plate, described core stamping excircle is evenly equipped with 4 ~ 6 fastening sheet mounting grooves, inner periphery is evenly equipped with some wedge-shaped coil grooves, and this wedge-shaped coil channel opening place is provided with the insulation board being fixed coil.
Compared with the prior art, the utility model is at stator core stamping sheet arranged outside fastening sheet mounting groove, adopt fastening sheet that punching riveting is tightened to an entirety, replace the installing hole of traditional stamping-out screw, nut, alignment pin etc. in punching, fastening sheet is compared with screw, nut, alignment pin etc., and it takes up room little, improve the magnetic property of stator core, reduce loss, required installing space is little, makes complete machine miniaturized while making stator core easy for installation; Stator core end face pastes insulating end plate, improves its insulating properties; Stator core inner periphery arranges wedge-shaped coil groove, the lead-out wire of enamelled wire effectively can be protected while improve winding efficiency, enamelled wire damage can be avoided to contact with iron core causes motor to puncture, thus improve the useful life of motor, and this wedge shape winding slot coiling amount is more, iron core winding utilance with size is high, and power is large, improves the performance of stator; Wedge-shaped coil groove itself plays good fixation to coil, add the insulation board that wedge-shaped coil channel opening place is arranged, not only good insulation effect is played to coil, and by coil compression tightly be fixed in wedge-shaped coil groove, improve the winding density of coil, can avoid while adding the twining amount of coil in use making because of vibrations coil landing cause motor failure.
