Abstract
The invention relates to an independent stator ventilating and cooling type permanent magnet motor. The problems that energy consumption is large and safety operation is affected due to the fact that an existing permanent motor is poor in cooling effect are solved. An air inlet is formed above an end cover of a transmission end. An air outlet is formed in an end cover of a non-transmission end. A ventilating shell is arranged on the periphery of a stator core. The inner wall of the ventilating shell is provided with a plurality of outer ventilating slots evenly distributed by using the center of the inner wall of the ventilating shell as the circle center. Two radially-distributed slot wedges are arranged inside each rectangular slot of the stator core. An air guiding plate sealed with the end cover of the transmission end and a slot wedge on the inner side of a stator end plate is arranged between the end cover of the transmission end and the slot wedge on the inner side of the stator end plate, and an air guiding plate sealed with the end cover of the non-transmission end and a slot wedge on the inner side of the stator end plate is arranged between the end cover of the non-transmission end and the slot wedge on the inner side of the stator end plate. According to the independent stator ventilating and cooling type permanent magnet motor, the structural design is reasonable and reliable, the special protective requirement of the permanent magnet motor can be met, a main heat source stator armature winding of the permanent magnet motor can be effectively cooled, and the heat dissipation capacity of the permanent magnet motor is brought into full play, so that the permanent magnet motor is efficient, saves energy and has the advantages of being simple in structure, convenient to machine and low in cost.
Description
Technical field
The present invention relates to magneto, be specially a kind of stator independent ventilation cooled magneto.
Background technology
Along with rare earth permanent-magnetic material develops rapidly, the progress of power electronics and Control Technique of Microcomputer, rare-earth permanent-magnet electric machine obtains application widely at industry-by-industry, in a large number efficiently, at a high speed, the product of high response speed and energy-conservation contour performance continues to bring out, magneto and supporting control system are with its superior performance, be that volume is little, quality is light, loss is few, efficiency is high, the shape and size of motor can be versatile and flexible etc. distinguishing feature, have the trend that progressively substitutes existing asynchronous machine and control system thereof.
In, high power density little, lightweight to magneto volume, high efficiency pursuit, design of electrical motor except Rational choice electromagnetic parameter, reduce heating and the loss of motor, also on motor cooling, constantly explore novel cooling structure to adapt to design of electrical motor requirement under different application environment, according to the custom-designed magneto of different loads characteristic, effectively utilize former having living space and electromechanics electrical apparatus interface and cooling system interface, carry out structural manufacturing process innovation and design optimization, substituting traditional Induction Motor System, is one of current magneto developing direction.
The cooling full-closed structure that substantially all adopts of existing magneto, cooling air can not enter stator core, armature winding, rotor core and magnet steel, and motor internal produces heat and mainly distributes by casing skin. Casing heat radiation mainly contains two kinds of modes: water-cooled and air-cooled. Water-cooling pattern is to have cooling water channel in the casing interlayer of motor, and in position intake-outlet is set, and cooling water flows through casing, takes away the heat producing in motor internal armature winding and iron core; Air cooling way adopt blower fan directly to motor housing blast-cold take away from motor internal heat. It is far from being enough that these two kinds of types of cooling only depend on the outer heat radiation of casing, the copper loss more than 80 percent producing by electric current from stator armature winding of magneto heating, and the iron loss that under high frequency, stator and rotor cores produces, this part heat cannot effectively distribute, energy consumption is larger, affects the safe operation of motor.
Summary of the invention
There is the poor problem that causes energy consumption greatly and affect safe operation of cooling effect in order to solve existing magneto in the present invention, a kind of stator independent ventilation cooled magneto is provided.
The present invention adopts following technical scheme to realize: stator independent ventilation cooled magneto, comprise stator core and be positioned at driving end end cap and the non-transmision end end cap of its left and right sides, the two ends of stator core are provided with stator end plate, driving end end cap top is provided with air inlet, on non-transmision end end cap, be provided with air outlet, the surrounding of stator core is provided with ventilation shell, and ventilation outer casing inner wall is provided with the separate ventilation groove that some Yi Qi center is the uniform setting in the center of circle; In the rectangular channel of stator core, be provided with two radially-arranged slot wedges, between slot wedge, be provided with the wind deflector with both sealings inside driving end end cap, non-transmision end end cap and stator end plate.
While ventilating cooling operations, cooling air enters to divide a two-way to carry out cooling to motor from motor air inlet, the separate ventilation groove of ventilation shell of leading up to carries out cooling to casing, the ventilation slot that two slot wedges of separately leading up to surround carries out cooling to electric machine stator iron and armature winding, wind deflector is guided to cooling air on stator core and armature winding, effectively isolate again the rotor with permanent magnet, overcome existing magneto and had the poor problem that causes energy consumption greatly and affect safe operation of cooling effect.
Reasonable in design of the present invention is reliable, can meet the special requirement of shelter of magneto, can carry out effectively cooling to the main thermal source stator armature of magneto winding again, give full play to the heat-sinking capability of magneto, make magneto energy-efficient, have advantages of simple in structure, easy to process and cost is low.
