Can a Series Capacitor Create Phase Alignment in DC Shunt Universal Motors?

AI Thread Summary
Universal Motors have field windings in series with the armature, lacking shunt fields due to their inductive reactance, which results in negligible torque on AC supply. The phase difference between currents in the series and shunt paths can lead to non-unidirectional torque, affecting performance. The discussion proposes using a series capacitor to align the phase of both currents, potentially reducing the impedance of the shunt path. The feasibility of this configuration is questioned, with a call for simulations or experimental assistance to explore the concept further. The exploration of phase alignment through a series capacitor could enhance the functionality of DC Shunt Universal Motors.

We know that Universal Motors have field winding always in series with the Armature.They do not have field in shunt because of shunt fields' inductive reactance & they will produce negligible torque on AC supply.
Also because of different phase angles of currents in series & shunt path, the 'DC Shunt Universal Motor' may not even have unidirectional torque.(since the field & Armature should be 'in phase' so that torque is unidrectional & having less ripples.)
So my quuestion is "what if we use a series capacitor having such a value so that both the currents are in phase ? And capacitor also will reduce the impedance of shunt path."
will this type of configuration be feasible?

Can anybody perform simulations/do experiments or help me in the same for above problem?
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
