Basic requirements for motor shafts What are the basic requirements for motor shafts?

(1) Must have sufficient strength. That is to say, under normal load and specified special conditions (such as sudden short circuit, etc.), any part of the shaft cannot produce residual deformation or damage.

(2) Must have sufficient rigidity. That is, the deflection of the rotating shaft must be within the allowable range.

(3) There should be sufficient difference between critical speed and working speed to avoid resonance.
