Abstract
The utility model discloses a motor rotor structure, comprising a cast-aluminum rotor (1) and a rotating shaft (2), wherein the cast-aluminum rotor (1) is mounted on the rotating shaft (2), the cast-aluminum rotor (1) comprises an iron core (11), an aluminium strip (12) embedded into the iron core (11) and a short circuit ring (3) located on the end face of the iron core (11), the short circuit ring (3) is connected with the aluminium strip (12), a plurality of fan blades (4) are arranged on the outer end face of the short circuit ring (3), the cross section of the fan blade (4) is S-shaped. According to the utility model, by increasing the air blow area of the fan blades, the motor temperature reduces rapidly, the motor temperature rise is effectively improved, and the performance indexes of the motor are improved.
Description
Technical field:
The utility model relates to the rotor technology, particularly a kind of motor rotor construction that increases rotor fan blade wind cutting face area.
Background technology:
At present, most motor rotor constructions all adopt straight type plane fan blade, and there are the following problems: 1) area of straight type plane fan blade is less, and therefore, the wind cutting area of fan blade is just smaller when rotor rotation, causes its radiating effect bad; 2) radiating effect is bad, and motor temperature raises very fast, and motor torque reduces, and causes the motor performance instability.
Summary of the invention:
The purpose of this utility model provides a kind of motor rotor construction, can form S type fan blade, increases rotor fan blade wind cutting face area and accelerates heat radiation, thereby reduce electric machine temperature rise, makes machine operation in preferable temperature, and the working stability life-span is longer.
The utility model is to be achieved by following technical scheme.
A kind of motor rotor construction, comprise cast-aluminum rotor and rotating shaft, cast-aluminum rotor is installed in the rotating shaft, cast-aluminum rotor comprises iron core, be embedded into the aluminum strip of iron core the inside and be positioned at short-circuited conducting sleeve on the iron core end face, short-circuited conducting sleeve and aluminum strip couple together, be provided with some fan blades on the outer face of short-circuited conducting sleeve, the shape of cross section of fan blade is the S type.
Above-mentioned described some fan blades are evenly distributed on the end face of cast-aluminum rotor.
Above-mentioned described short-circuited conducting sleeve, aluminum strip and fan blade are one-body molded.
Above-mentioned described fan blade is thicker near an end of short-circuited conducting sleeve, and is thinner away from an end of short-circuited conducting sleeve.
The utlity model has following advantage: the shaped design of fan blade becomes the S type, has increased the wind cutting face area of fan blade, accelerates heat radiation, thereby reduces electric machine temperature rise; Experimental results show that: the wind cutting face area of fan blade has increased about 14%, makes motor temperature reduce comparatively fast, and is more, heat dissipation capacity has increased about 20% in the working unit time, make machine operation in preferable temperature, the working stability life-span is longer, has improved motor performance index.
