Abstract
The utility model disclose an interelectrode-wiring structure of a high-speed motor rotor, which includes a rotating shaft, a magnetic yoke sleeved on the rotating shaft, magnetic poles uniformly distributed and mounted on the outer surface of the magnetic yoke, and magnetic pole coils wound around the magnetic poles, wherein an annular connecting rank is arranged overhead on the surface of the rotating shaft and close to one end surface of the magnetic yoke; and the joint of every magnetic pole coil, which is close to the magnetic yoke, and is led to the outer surface of the connecting rank according to proximity principle, and radially fixed on the connecting rank through a bolt. The interelectrode-wiring structure of the high-speed motor rotor enables joint connecting points among the magnetic pole coils and close to the magnetic yoke to be reliably guaranteed in the aspects of mechanical insulation and electric insulation.
Description
Technical field
The utility model relates to a kind of interpolar connecting line construction of high speed rotor of motor.
Background technology
Four common utmost point synchronous motor structures are very compact and have a high rotational speed, its rotating speed reaches 1500r/min, runaway speed reaches 1800r/min, thus to its rotating part particularly the stress of rotor coil, pole shoe, pole shoe bolt, wiring etc. require just than higher.Traditional pole coil near the interpolar connecting line construction of yoke is: the joint 40 of the pole coil 4 of rotor directly in the space between two adjacent magnetic poles 3 and the headgear weldering connect bag insulation 8 again, as Fig. 1.Its drawback is: because the narrow space between the magnetic pole, operating difficulties when not only welding, and the position and the space of no any fixing, colligation after welding, therefore at the bigger high-speed electric expreess locomotive of relative linear velocity, especially large-diameter rotor is a big hidden danger place that easily produces mechanical failure, damage in insulation herein.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of interpolar connecting line construction of high speed rotor of motor to be provided, and it can make the joint tie point of the close yoke of pole coil reliably be guaranteed at machinery and electric insulation.
The technical scheme that realizes above-mentioned purpose is: a kind of interpolar connecting line construction of high speed rotor of motor, comprise rotating shaft, be sleeved on yoke in the rotating shaft, some uniform magnetic poles that is installed in the yoke outer surface and the pole coil on the magnetic pole, wherein, the vacant lot of putting on the shelf on the surface of the described rotating shaft of an end face of pressing close to described yoke is provided with the connection row of a ring-type, is introduced to described connection row near the joint of described yoke on the described pole coil and radially is fixed in the described rotating shaft in the lump with bolt.
The interpolar connecting line construction of above-mentioned high speed rotor of motor, wherein, the connected mode of the joint of close described yoke is to guide to described connection row near the joint of described yoke on two adjacent pole coils on described each pole coil, row connects by described connection, and with described bolt with described joint with described be connected to arrange be fixed in the lump in the described rotating shaft.
The interpolar connecting line construction of above-mentioned high speed rotor of motor, wherein, described connection row is built on stilts by a plurality of lip-deep bakelite plates of described rotating shaft that are fixed in uniform way.
The technical scheme of the interpolar connecting line construction of high speed rotor of motor of the present utility model, employing will move to the termination of pole coil from two adjacent interpolars near the joint tie point of yoke on the pole coil, easy to operate in the time of can making connection, and the joint tie point of close yoke on the pole coil is reliably guaranteed at machinery and electric insulation.
Description of drawings
Fig. 1 is the schematic diagram of interpolar connecting line construction of the high speed rotor of motor of prior art;
Fig. 2 is the schematic diagram of the interpolar connecting line construction of high speed rotor of motor of the present utility model.
Embodiment
Also in conjunction with the accompanying drawings the technical solution of the utility model is described below by specific embodiment:
See also Fig. 2, the interpolar connecting line construction of high speed rotor of motor of the present utility model comprises rotating shaft 1, is sleeved on yoke 2 in the rotating shaft 1, four uniform magnetic poles 3 that are installed in yoke 2 outer surfaces and the pole coil 4 on the magnetic pole 3.
Be provided with the connection row 5 of a ring-type on the surface of the rotating shaft 1 of an end face of pressing close to yoke 2, this connections row 5 is maked somebody a mere figurehead by a plurality of rotating shaft 1 lip-deep bakelite plates 6 that are fixed in uniform way also built on stiltsly.
Joint near yoke 2 on each pole coil 4 is introduced to connection row 5, and is fixed in the lump in the rotating shaft 1 with bolt 7.
In order to improve operating efficiency, the best connected mode of joint near yoke 2 on each pole coil 4 is that the joint near yoke 2 on two adjacent pole coils 4 is introduced to connection row 5, and is fixed on together in the rotating shaft 1 with bolt 7 and bakelite plate 6.
The interpolar connecting line construction of high speed rotor of motor of the present utility model, because connecting row 5 is maked somebody a mere figurehead by bakelite plate 6, so whole connector need not insulation, therefore this connecting line construction is simple and be convenient to operation, and the joint tie point of the close yoke 2 between pole coil is reliably guaranteed at machinery and electric insulation, make this ring weak in the rotor of four utmost point motors, promoted a step from designing quality.
By the secure fixation of bolt 7 being connected row 5 Stress calculation, the stress that draws bolt 7 is significantly smaller than the allowable stress of general bolt in addition.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
