9.1.2.1
Frequency sweep vibration
Drive motors and drive motor controllers shall be able to withstand frequency sweep vibration tests of three
directions - X, Y, Z. If there is no special provision, according to installation position, severe grade of frequency
sweep vibration test of drive motors and drive motor controllers shall meet regulations of

Note 1: Amplitude and accelerated speed are used for “Z” direction; for the “X” and “Y”, its amplitude and
accelerated speed can be divided by 2 in the table.
Note 2: Stipulated direction during vibration test shall be: parallel direction of engine cylinder-hole axis
when products are installed at engine; parallel direction of the vertical direction of vehicles when
product is installed at other parts.
Drive motors and drive motor controllers shall usually be inspected under the condition of not-energized.
Checkpoints of vibration test generally are the junction of test fixture and test-bed. After vibration test, parts
shall have no damage, fasteners shall not be loose; drive motors and drive motor controllers shall work properly
under the rated voltage, continuous torque and continuous power.
9.1.2.2
Random vibration
Drive motors and drive motor controllers shall bear random vibration tests of three directions- X, Y, Z. If there is
no special provision, according to installation position, severe degree limit of random vibration and test duration
of motors and controllers shall comply with regulations of GB/T 28046.3-2011.
Drive motors and drive motor controllers shall usually be inspected under the condition of not-energized.
Checkpoints of vibration test generally are the junction of test fixture and test-bed. After vibration test, parts
shall have no damage, fasteners shall not be loose; drive motors and drive motor controllers shall work properly
under the rated voltage, continuous torque and continuous power.
