Abstract
A motor casing with an outer rotor belongs to the technical field of motor manufacturing and mainly comprises an outer rotor iron core 1, a casing 2 and a conducting bar 3. The utility model has the advantages of reasonable design, reduced external rotor electric machine's spare part, practiced thrift a large amount of man-hours of processing to it is more reliable when making motor external rotor transmission torque.
Description
The utility model relates to a kind of motor case with external rotor, belongs to the motor manufacturing technology field.
Existing external rotor electric machine, motor case is two parts that separate with external rotor, after promptly casing and external rotor process respectively, then external rotor is pressed in the casing, and form certain interference fit, rely on the torque that the magnitude of interference that casing cooperates with external rotor transmits motor.This structure workpiece is many, makes complexity, and quality of fit requires high.And, make casing and external rotor all be subjected to bigger mechanical stress owing to rely on interference to come transfer torque.And the casing of external rotor electric machine is generally thin-wall construction, and excessive mechanical stress is easily brought hidden danger to casing.
The purpose of this utility model provides a kind of reasonable in design, can make the motor case of the band external rotor of the novelty that motor case and external rotor combine together.
The utility model comprises outer rotor iron core for the motor case of band external rotor, and casing places the sliver in the external rotor, it is characterized in that described outer rotor iron core and casing, and sliver is cast into an integral body.The material of described casing and sliver can be aluminium alloy.
The utility model reasonable in design, the casing and the external rotor die casting of motor is as a whole, saved each road manufacturing procedure of chassis cavity and external rotor cylindrical, overcome the mechanical stress that because of interference fit casing is caused in the prior art, because casing and external rotor combine together, have improved the ability of transfer torque between the two greatly.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is an A-A face structure cutaway view shown in Figure 1.
Below in conjunction with embodiment the utility model is further described:
The utility model mainly comprises outer rotor iron core 1, and casing 2 places the interior sliver 3 of outer rotor iron core etc.During manufacturing, the blower fan external rotor electric machine that with rated power is 2.1KW is an example, earlier become outer rotor iron core 1 by the thick silicon steel plate stacking of 0.5mm, and aluminium alloy is gone in die casting in iron core cylindrical and appearance wire casing, after treating that aluminium alloy solidifies, promptly constitute the casing 2 and the rotor bar 3 of motor, thereby constituted, the motor case that outer rotor iron core 1 and sliver 3 combine together by motor case 2.
Claims (2)
1, a kind of motor case with external rotor comprises outer rotor iron core (1), casing (2), and sliver (3) is characterized in that described outer rotor iron core (1) and casing (2), sliver (3) is cast into an integral body.
2, by the motor case of the described band external rotor of claim 1, it is characterized in that the material of described casing (2) and sliver (3) can be aluminium alloy.
