Brushless DC Motors – Part I: Construction and Operating Principles
... has lower inductance, thus it can run at very high speeds. Because of the absence of teeth in the lamination stack, requirements for the cogging torque also go down, thus making them an ideal fit for low speeds too (when permanent magnets on rotor and tooth on the stator align with each other then, ...

From Faraday`s Law to Displacement Current
... Consider the parallel plate capacitor and suppose a current ic is flowing charging up the plate. If Ampere’s law is applied for the given path in either the plane surface or the bulging surface we should get the same results, but the bulging surface has ic=0, so something is missing. ...
