Do Displacement Currents Exist In Electric Motors

  1. May 15, 2008 #1
    I am not asking if they are considered as input into the armature's magnetic field. I strongly believe they are NOT even considered when designing motors.

    The question is, "DO THEY EXIST IN MOTORS?"

    Based on evidence from conventional theory, it appears they do infact affect the output of the magnetic field, but to what degree will depend on the design of the motor. I believe that looking in most designs for motors will suggest the displacement current is irrelevant when determining the performance of the motor.

    I am just looking for an answer from someone who knows about this better than I do.

    Any time there is a changing magnetic field in a region of space where there are no currents, there is a displacement current. So, yeah, there are displacement currents.
