When the coupling is linked, can the drive shaft be thinner than the motor shaft?
Coupling calibration is not required if the motor shaft and the drive shaft misalignment is that your motor installation seat problems both have, because you find it to two concentric since coupling is not so high the
More consideration should be given to the load capacity of the transmission shaft (strength, rigidity, mechanical performance), and if the load is small and the shaft length is not long, the transmission shaft can be smaller than the motor shaft.
Actually, the problem is mechanical mechanics.On the one hand, the size of the drive shaft in addition to considering the matching of the motor shaft
