A model for the fringing field in sections of circular parallel plates is derived using potential‐theoretic methods. The calculation accurately predicts fringing effects when the overlapping area is varied by one plate being slided on top of one another. This capacitance calculation can be useful to estimate torque in several micromotor configurations.
