Radial forces between a stator segment and rotor
The force of attraction F
the air gap. The variable F
following diagram shows the relative dependency of the force of attraction F
the air gap.

NOTICE
Radial forces increase exponentially
The stator and rotor can suddenly slam together if the distance between the stator and rotor
is too low.
• When mounting and removing rotors, use the appropriate mounting equipment.
