1-11

 Resistance to vibration 

The resistance to vibration of the motor is as follows, and this value is the same in up/down, left/right 

and front/rear directions: 

Vibration acceleration: 25 m/s

2 

(frequency: 10 to 400 Hz) 

In our test, the motor is tested for 2 hours in each direction at a vibration frequency sweep period of 10 

minutes.
