Patent Office of the People's Republic of China also discloses one piece of utility model patent relevant with the direct driving motor testing table, promptly a kind of 1500kW permanent magnet direct-driving aerogenerator group emulation test system (ZL200820153636.X).This utility model patent uses variable-frequence governor control dragging motor through the power source of speed reduction unit as the 1500kW permanent magnet direct-driving aerogenerator, to reach the purpose of emulation testing; The testing table of this utility model only can be tested the permanent magnet direct-driving aerogenerator that power is not more than 1500kW.This structural design is that the mode of drive motor acceleration and deceleration device drags tested motor in essence.
Summary of the invention
In order to solve the stuck phenomenon that structural shape that present two motor free beam modes drag back-to-back occurs once in a while in process of the test, and the structural shape that adopts drive motor acceleration and deceleration device to drag tested motor is subjected to the problem of place restriction again, the utility model provides a kind of direct driving motor testing table, can test the direct driving motor of different structure, different capacity and different exciting mode.This device comprises: basis, melt pit, motor fixed rack, interface cover and shaft coupling.Wherein the basis is a reinforced concrete structure, is provided with melt pit in the middle of the basis and is used for holding two direct driving motors; The basis of melt pit both sides is equipped with two motor fixed racks and is used for fixing two direct driving motors; Shaft coupling is used for connecting the interface cover that the moving axis that is installed on two direct driving motors on the motor fixed rack is joined.
The key distinction of this utility model and existing direct driving motor testing table is: one, electric machine structure is not limit: dragging motor and tested motor all can be internal rotor or outer rotor; Two, the motor excitation mode is not limit: dragging motor and tested motor all can be permanent magnet excitation or electric excitation; Three, power of motor is not limit: other direct driving motor of different capacity level all can be tested on testing table; Four, connecting mode is flexible: can be equipped with different joint flanges, interface cover and current transformer the direct driving motor of two different sizes is tested.
The utlity model has that parts are few, simple in structure, disassembling and assembling machine is convenient and do not need medium characteristics, its beneficial effect comprises:
The first, can apply to the test of the direct driving motor of different structure, different capacity, different exciting mode;
The second, can carry out polytype tests such as delivery test, performance test and type approval test;
Three, when the direct driving motor of different size is tested, can install by different joint flange and interface covers according to their different structure designs, being equipped with corresponding separately current transformer simultaneously can test;
Four, can be when testing table be installed disposable centering of finishing the motor fixed rack of both sides, no matter be the test of carrying out the same size motor, still carry out the test of different size motor, only need to install corresponding joint flange, interface cover and shaft coupling, need not centering when testing the motor test that more renews after finishing, avoided this loaded down with trivial details work from design, easy to use;
Five, direct driving motor testing table floor area of the present utility model is little.
