Air gap and assembly concentricity
Air gap, existing between stator and rotor, prevents the motor from any damage during rotation. As long as you
follow the standard value of air gap and the requirement of assembly concentricity established in Fig. 4.10 and
the Table 4.9 to Table 4.11, the motor will not be interfered during rotation.
