To prevent magnet interference from affecting motor performance, there should be some space between
customer’s shaft and rotor magnet. The recommended dimension of outside diameter (
∅
D
) inside diameter
(
∅
d
) and flatness specification of rotor mounting surface (Flatness A) is given in Table 4.7, Table 4.8.
