Frequently asked question (FAQ)

Question: The material of this product is aluminum alloy. Is it strong enough?
Answer: After testing, the stress generated by the motor at 6,000 revolutions per minute is 19MPa, which is fully sufficient for use considering that the yield strength of aluminum alloy A6061 is 55MPa. In addition, when the motor rotates at 6,000 revolutions per minute, the maximum deformation of the mounting hole of the motor bracket is 0.00206mm, so the deformation will not lead to screw loosening or cause the motor to fall off.
Question: What is the strength grade of the screws used for the motor flange mounting holes of this product?
Answer: There is no problem even with screws of grade 12.9. If you want to use screws of other special specifications or fix the motor in other ways, please contact MISUMI for confirmation.
