Hello,
I'm currently designing a mounting base for a motor running at a constant speed of 1700 rpm for an undergraduate project.
I've already run a linear static stress simulation and a modal analysis. The first two natural frequencies resulted in about 143 Hz and 292 Hz.
However, I wonder how to tell at what frequency of vibration the motor base will be subject to, in order to guarantee a safe operation of the motor.
Can you help me with that?
Thank you,
Roberto

Hi Roberto,
The mounting base will vibrate due to resonance with the motor if the motor operates at 143 rev/sec (8580 RPM) or 292 rev/sec (17,520 RPM). (In other words, 1 Hz = 1 cycles/sec = 1 rev/sec.) Since the motor is operating at a much lower speed, there should not be a problem with resonance. Unless the motor or its load is severely unbalanced, I think that it is unlikely that the motor will cause any vibration problem.
