Abstract
The utility model relates to a novel rotor core heat radiation apparatus of switch magnetic resistance motor, which comprises a motor shaft; the motor shaft is passed successively through a through hole formed on the center of the motor rotor and the through hole formed on the fan center; a bayonet catch is disposed on the fan; and the bayonet catch is clamped in a groove formed on the motor shaft. In the utility model, a fan is fixed on the motor shaft of the switch magnetic resistance motor; while the motor rotor is rotating at a high speed, the fan is also rotating at a high speed to discharge the hot-air inside the motor to outside, and take new air into the motor simultaneously to form a ventilation loop. Thereby the apparatus of the utility model can guarantee the temperature of the motor to rise very slow when the rotor is rotating at a high speed, has a good heat radiation effect, and enable the switch magnetic resistance motor to work for a long time under the condition of high torque.
Description
Technical field
The utility model relates to a kind of heat abstractor, especially a kind of novel switched reluctance motor rotor core heat abstractor.
Background technology
There is not fan on the rotor of conventional switch reluctance motor, the inside of the motor stream of can't ventilating, it is very fast that the internal temperature of rotor motor under the situation of high-speed cruising rises, what cause that the temperature of whole motor rises is also very fast, radiating effect is poor, causes switched reluctance machines to work under the condition of long-time, high torque (HT).
The utility model content
The purpose of this utility model is to provide that a kind of cost is low, the novel switched reluctance motor rotor core heat abstractor of good heat dissipation effect.
For achieving the above object, the utility model has adopted following technical scheme: a kind of novel switched reluctance motor rotor core heat abstractor, comprise motor shaft, pass in the through hole that the through hole that described motor shaft is offered from the rotor center successively, fan center offer, buckle is set on the fan, and this buckle is stuck in the groove of offering on the motor shaft.
As shown from the above technical solution, the utility model sets firmly a fan on the motor shaft of switched reluctance machines, rotor is under the situation of high-speed cruising, fan makes the hot-air of motor internal discharge to the outside of motor also at high-speed cruising, has new gas to enter motor internal simultaneously, form ventilation circuit, what guarantee rotor temperature rises when high-speed cruising is very slow, and good heat dissipation effect can be worked switched reluctance machines under the condition of long-time, high torque (HT).
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of fan among Fig. 1.
Embodiment
A kind of novel switched reluctance motor rotor core heat abstractor, comprise motor shaft 1, pass in the through hole that the through hole that described motor shaft 1 is offered from rotor 2 centers successively, fan 3 centers are offered, buckle 7 is set on the fan 3, this buckle 7 is stuck in the groove of offering on the motor shaft 1, as shown in Figure 1.
As shown in Figure 1, 2, offer groove on the described rotor, the flat key that is provided with on this groove and the motor shaft 1 matches.Two bearings 4 are set on the described motor shaft 1, described bearing 4 is a rolling bearing, rotor 2 and fan 3 are between two bearings 4, the flabellum 6 of fan 3 is arranged towards bearing 4, offer 2～4 holes 5 on the flabellum 6 of described fan 3, the effect of further help heat radiation is played in hole 5 on the one hand, can alleviate the weight of fan 3 on the other hand, guarantees radiating effect.One end installation and control device of motor shaft 1, the other end of motor shaft 1 links to each other with the gearbox input.The utility model has been fixed a fan at an end of the motor shaft of switched reluctance machines, make rotor rapid heat dissipation when high-speed cruising, overcome the slow shortcoming of conventional switch reluctance motor heat radiation, the slow failure rate of motor radiating is reduced, safe and reliable, guarantee that switched reluctance machines can work under the condition of long-time, high torque (HT).
