Abstract
The utility model relates to an outer rotor stepless speed regulating motor. The utility model solves the long-standing problem of the heating of the rotor when the motor is adjusted to run in a state of low speed and constant-torque moment by the adoption of a compound outer rotor, a heat radiation rib which is attached to the outer surface of the rotor, fan cooling technology, etc. to achieve the purposes of raising the operation range and reliability of the speed-regulating motor. The utility model has the advantages of simple structure, easy fabrication, low cost and convenient operation.
Description
The utility model belongs to the AC induction motor technical field.
Two class technical measures below present motor with stepless speed regulation adopts when solving heat dissipation problem usually, one class is the coil wound rotor motor, by the outer meeting resistance speed governing operation, the rotor loss is dispelled the heat through outer meeting resistance, make the motor internal temperature rise lower, this type of electric machine structure complexity has slip ring processed complex, cost higher; Another kind of is to adopt hollow shaft to make rotating heat pipe in the motor internal rotor to solve rotor heat dissipation problem (referring to " middle and small motor " application of the 4th phase-rotating heat pipe on phase asynchronous adjustment motor in 85 year), this type of motor processed complex, cost height.
The purpose of this utility model provides a kind of compact conformation, speed adjustable range is wide, the motor with stepless speed regulation of rotor good heat dissipation effect.
For achieving the above object, the technical solution of the utility model is: adopt the outer-rotor structure form, external rotor and rotating shaft fixed axisymmetricly, with stator be fixed on one "
" on the horizontal gird of shape support; machine shaft passes from this crossbeam center; the two ends of this support vertical beam are separately fixed on the support; external rotor is sleeved on the stator periphery; in addition; the outer surface at external rotor is attached with some radiating ribs vertically, heat on the external rotor can be propagated in air by these radiating ribs, corresponding with the thermolysis of radiating ribs, seam is equipped with cooling fan behind support, and the support front portion has the ventilation and heat mouth, like this, the heat that the air-flow that produces when fan rotates just can be transmitted to external rotor on the radiating ribs effectively is discharged to motor body space in addition, thereby reduces the temperature rise of motor internal.
In addition, consider that motor is at a high speed or the state of low cruise through regular meeting, outside in the rotor core material; some conductivity that evenly distribute vertically are higher than the metal conductive strips of core material; like this, when the motor high-speed cruising, these metal conductive strips can play the effect that reduces the wastage.
The utility model has promptly kept asynchronous machine machining characteristics simple in structure, easy; improved simultaneously rate of heat exchange again; solved the problem of the permanent torque rotors heat radiation of buncher low speed for a long time; the range of operation and the reliability of buncher have been improved greatly; be used with microcomputerized controller; can realize multiple functions such as adjusting microinching operation, brake shutdown, soft start, soft stop, rotating, stepless speed regulation, control automatically, fault self-diagnosis, greatly facilitate the user and use.
Accompanying drawing 1 the utility model structure division cutaway view
Below in conjunction with accompanying drawing, introduce a most preferred embodiment of the present utility model.
Support (5), support (3) all cylinder iron or low carbon steel plate make, stator (6) adopts silicon steel plate to be overrided to form, stator (6) is fixed on the support (3), rotating shaft is passed from the rack beam center, external rotor (7) adopts cantilever (8) support structure to be fixed on support (3) the middle back shaft extension (9), detecting element (2) is housed on the front axle (1), seam is equipped with cooling fan (10) behind the support, there is heat dissipation ventilation mouth (4) the support front portion, the core material of external rotor (7) adopts common medium-carbon steel or mild steel to process, again through boring, technologies such as cast aluminium embed aluminum strip, cast out some radiating ribs vertically at rotor outer surface in addition, and aluminum strip and end ring are together cast out.Most of heat when this motor low cruise on the external rotor is transmitted on the radiating ribs, the air-flow that the fan that is cooled then produces is taken out of outside the motor body, when this motor high-speed cruising, because kelvin effect, aluminum strip plays a major role, can reduce the loss of rotor, improve upper limit rotating speed.
