Abstract
The utility model discloses an aluminum casting rotor core of an explosion-proof motor. The rotor core comprises an iron core, wherein the iron core is equipped with a bearing hole and air vents, a first aluminum ring and a second aluminum ring are respectively arranged in sides of the iron core along the circumferential direction, and the first aluminum ring is equipped with multiple wind wheel along the circumferential direction. Preferably, the first aluminum ring is equipped with 13 wind wheels along the circumferential direction. By employing to aluminum casting rotor core to produce the explosion-proof motor, an explosion-proof motor manufactures requires no additional blower fans for heat radiation, wherein the built-in wind wheels of the rotor core can achieve heat radiation effects, thereby saving production procedures, and improving the sealing and safety performance of the whole motor.
Description
Technical field
The utility model relates to a kind of fire-proof motor cast-aluminum rotor iron core.
Background technology
Present fire-proof motor rotor does not arrange the fan blade of heat transmission usually, motor manufacturer needs extra design heat abstractor when the design fire-proof motor, method commonly used is that the blower fan of heat transmission is installed at motor, this design has caused the increase of installation procedure on the one hand, on the other hand owing to increased electric wiring, cause the sealing effect to reduce, affect the explosion-proof effect of fire-proof motor.
The utility model content
The purpose of this utility model is to provide a kind of fire-proof motor cast-aluminum rotor iron core, has reduced installation procedure and energy Effective Raise fire-proof motor overall tightness and fail safe in the motor manufacture process.
For achieving the above object, the technical solution of the utility model is: a kind of fire-proof motor cast-aluminum rotor iron core, comprise that iron core, this iron core are provided with dead eye, ventilation hole, it is characterized in that: the iron core side also along the circumferential direction is provided with the first aluminium ring, the second aluminium ring, also along the circumferential direction is provided with some fan blades on the first aluminium ring.
Also along the circumferential direction be provided with 13 fan blades on described the first aluminium ring.
The beneficial effects of the utility model are: should be in the energising situation, cast-aluminum rotor begins to rotate, the fan blade that cast-aluminum rotor is provided with can play the effect of heat radiation, fire-proof motor manufacturer is when producing fire-proof motor with this cast-aluminum rotor, the blower fan that does not need again extra increase heat transmission, the fan blade that relies on rotor to carry can reach radiating effect, thereby has saved the operation that blower fan is installed and the required electric wiring of blower fan, the sealing and the fail safe that have improved motor integral body are installed.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2: a kind of fire-proof motor cast-aluminum rotor iron core, comprise that iron core 1, this iron core 1 are provided with dead eye 6, ventilation hole 3, iron core 1 side also along the circumferential direction is provided with on the first aluminium ring 4, the second aluminium ring 5, the first aluminium rings 4 and along the circumferential direction is provided with some fan blades 2.Also along the circumferential direction be provided with 13 fan blades 2 on described the first aluminium ring 4.
When the utility model uses, in the energising situation, cast-aluminum rotor begins to rotate, the fan blade that this cast-aluminum rotor is provided with can play the effect of heat radiation, fire-proof motor manufacturer does not need the blower fan of extra increase heat transmission again when producing fire-proof motor with this cast-aluminum rotor, the fan blade that relies on cast-aluminum rotor to carry can reach radiating effect, thereby saved the operation that blower fan is installed and the required electric wiring of blower fan, the sealing and the fail safe that have improved motor integral body have been installed.
