Abstract
The utility model discloses a kind of series excited motor rotor with internal heat dissipation structures, including rotating shaft, chip, dividing plate, middle and lower part is provided with the groove of column on the inside of the rotating shaft, exhaust vent is provided with the middle part of the rotating shaft, the exhaust vent is connected with groove, and the chip nesting is arranged in the middle part of rotating shaft, and dividing plate is additionally provided between the chip, air guide hole is provided with the dividing plate, the air guide hole is connected with exhaust vent.Centrifugal force is produced during running at high speed by series excited motor rotor, suction air effect is occurred according to groove on rotor, cool exterior air is sucked internal rotor and absorbs internal heat and is discharged by the opening on dividing plate, effectively cool to rotor, solve the problems, such as that rotor heating is serious, make motor stabilizing safe handling.
Description
Technical field
It the utility model is related to series excited machine field, and in particular to a kind of series excited machine with internal heat dissipation structures turns
Son.
Background technology
The radiating mode of existing common series-wound motor, mainly by the cooling fan and casing installed on armature spindle
Heat emission hole radiated, and reach the cooling purpose of motor.This method is come for the stator of motor with rotor surface
Say it is effective, but for the internal rotor pyrotoxin of motor, the effect of radiating is limited.Thus in motor interior
The heat dissipation problem of rotor is so far without relatively effective method.
Utility model content
In view of the above-mentioned problems, the utility model aims to provide a kind of series excited motor rotor with internal heat dissipation structures.
To realize the technical purpose, scheme of the present utility model is：A kind of series excited machine with internal heat dissipation structures turns
Son, including rotating shaft, chip, dividing plate, rotating shaft inner side middle and lower part are provided with the groove of column, are provided with the middle part of the rotating shaft
Exhaust vent, the exhaust vent are connected with groove, and the chip nesting is arranged in the middle part of rotating shaft, are additionally provided between the chip
Dividing plate, air guide hole is provided with the dividing plate, the air guide hole is connected with exhaust vent.
Preferably, the chip is three, one piece of dividing plate is each provided with respectively between the chip.
The beneficial effects of the utility model, centrifugal force is produced during running at high speed by series excited motor rotor, according to
Suction air effect occurs for groove on rotor, and cool exterior air is sucked into internal rotor and absorbs internal heat by opening on dividing plate
Mouth discharges, and effectively cools to rotor, solves the problems, such as that rotor heating is serious, makes motor stabilizing safe handling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is profile of the present utility model.
Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-2, specific embodiment described in the utility model is a kind of series excitation electricity with internal heat dissipation structures
Machine rotor, including rotating shaft 1, chip 2, dividing plate 3, the inner side middle and lower part of rotating shaft 1 are provided with the groove 4 of column, the rotating shaft 1
Middle part is provided with exhaust vent 5, and the exhaust vent 5 connects with groove 4, and the nesting of chip 2 is arranged on the middle part of rotating shaft 1, described
Dividing plate 3 is additionally provided between chip 2, air guide hole 6 is provided with the dividing plate 3, the air guide hole 6 is connected with exhaust vent 5.
In order that more preferably being radiated between chip, the chip 2 is three, and one piece is each provided with respectively between the chip 2
Dividing plate 3.
The solid rotor axle of motor on the premise of intensity requirement is met, hollow shaft is changed to by solid shafting by this practicality,
Groove is set among rotating shaft, while is each provided with one piece of dividing plate respectively between the chips, air guide hole is provided with dividing plate, is formed
Complete air-guiding aisle.Suction air effect is occurred according to groove on rotor, cool exterior air is sucked into internal rotor and absorbed
Internal heat is discharged by the opening on dividing plate, effectively cools to rotor, solves the problems, such as that rotor heating is serious, make motor
Stable safe handling.
Described above, preferred embodiment only of the present utility model is every according to this not to limit the utility model
Any trickle amendment, equivalent substitution and the improvement that the technical spirit of utility model is made to above example, it should be included in this
Within the protection domain of utility model technical scheme.
