Description
Technical field
This utility model relates to rotor structure of switching reluctance dynamo, specifically a kind of switch reluctance machine rotor integral structure.
Background technology
Switched reluctance machines is a kind of novel buncher, and governing system has direct current concurrently, exchanges the advantage of two class governing systems, is the latest generation stepless time adjustment system of frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor of continuing.Its simple in construction is firm, speed-regulating range width, and speed adjusting performance is excellent, and all has greater efficiency in whole speed adjustable range, and system reliability is high.Household electrical appliance air-conditioning, soy bean milk making machine, vacuum cleaner, wall-breaking machine, cooking machine, blender and small-sized electric tool are applied relatively broad.
The rotor of existing switched reluctance machines presses armature spindle after typically being laminated by rotor punching, installs fan and position sensor the most again.So existing when producing high-speed electric expreess locomotive and install trouble, concordance is bad, low precision, dynamic balance checking difficulty, noise and the shortcoming such as vibrations are big.
Utility model content
The utility model proposes a kind of switch reluctance machine rotor integral structure.
The technical solution of the utility model is achieved in that a kind of switch reluctance machine rotor integral structure, it is characterized in that: include rotor punching, armature spindle and molded portion, described rotor punching is multi-disc, and described multi-disc rotor punching overlaps together, and links together with armature spindle；Described molded portion includes molded portion leading portion, molded portion stage casing and molded portion back segment；Described molded portion leading portion is position sensor, and described molded portion back segment is fan blade, and described molded portion stage casing is connecting portion, and molded portion leading portion is coupled together by described molded portion stage casing with molded portion back segment；Rotor punching and armature spindle are fixed together by described connecting portion；Described molded portion leading portion, molded portion stage casing and molded portion back segment three are single injection-molded；Described connecting portion is provided with multiple cavity near one end of fan blade.
Owing to have employed technique scheme, this utility model has a beneficial effect highlighted below:
1, molded portion leading portion, molded portion stage casing and molded portion back segment three are single injection-molded.Rotor structure is pressed armature spindle by after originally first being laminated by rotor punching, the split-type structural of fan and position sensor is installed the most again, makes rotor punching, armature spindle, fan blade and position sensor become an entirety by the way of integral molded plastic.Making rotor structure more firm, concordance is good, and production efficiency is high, greatly reduces noise and vibrations.
2, described connecting portion is provided with multiple cavity near one end of fan blade, i.e. alleviates weight improve again the yield rate of injection by arranging multiple cavity.
3, simple in construction, using effect are good, it is simple to promote and use.
Accompanying drawing explanation
