Do Displacement Currents Exist In Electric Motors

[kmarinas86]

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.

I can provide an informed response to this question. Displacement currents do exist in electric motors, but their impact on motor performance may vary depending on the specific design and operating conditions of the motor.

Displacement current is a phenomenon that occurs when a changing electric field induces a magnetic field. This is described by Maxwell's equations and is a fundamental concept in electromagnetism. In an electric motor, displacement current can occur in the air gap between the stator and rotor, as well as in the windings of the motor.

While displacement current may not be a primary consideration in the design of electric motors, it is still a factor that can affect motor performance. For example, in high-speed motors, the displacement current in the air gap can lead to eddy currents, which can cause heat buildup and decrease efficiency. In addition, displacement current in the windings can result in increased losses and reduced power output.

Therefore, while displacement current may not be a major factor in motor design, it is still present and can impact the performance of electric motors. It is important for motor designers to consider displacement current and its potential effects in order to optimize motor performance.
