Road and multiple magnet 133, rotor and circuit connection are placed between magnet 133, and detection box 13 and the junction setting of rotor are more
A vibrating sensor 15, vibrating sensor 15 are connect with cylinder 14；
By the way that rotor to be placed in detection box 13, powering on makes rotor be rotated in magnetic field, and when rotation controls cylinder
14 put down vibrating sensor 15, the vibration frequency of various pieces when detection rotor rotates, to be carried out to the rotating property of rotor
Test；
Bolster 5 is set between support plate 16 and rack 3, bolster 5 includes axis 51, on axis 51 setting offset with support plate 16
Jacking block 52, the spring 53 that 52 lower section setting of jacking block offsets with rack 3, nut 54 is arranged in 51 bottom of axis；
In order to exclude some external interference, mechanism for testing 1 and rack 3 are arranged to one layer of buffer strip, pass through bolster 5
Cushioning effect, influence of the reduction system error to the result of test.
