Goes into technicalities

The lead paragraph of the article goes into a lot of technical terms without explaining them:

The universal motor is so named because it is a type of electric motor that can operate on both AC and DC power. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. It is often referred to as an AC series motor. The universal motor is very similar to a DC series motor in construction, but is modified slightly to allow the motor to operate properly on AC power. This type of electric motor can operate well on AC because the current in both the field coils and the armature (and the resultant magnetic fields) will alternate (reverse polarity) synchronously with the supply. Hence the resulting mechanical force will occur in a consistent direction of rotation, independent of the direction of applied voltage, but determined by the commutator and polarity of the field coils.[1]

This assumes that the reader understands terms like "commutated series-wound motor". NotYourFathersOldsmobile (talk) 02:07, 18 March 2016 (UTC)[reply]

Torque speed characteristic

First paragraph, last sentence of this section: This suits large inertial loads as the speed will drop until the motor slowly starts to rotate and these motors have a very high stalling torque. Surely this is incorrect; the speed won't/can't drop from zero but certainly the current will. 2404:4402:17AC:DF00:4DDE:11E4:7310:F8E0 (talk) 22:05, 21 October 2021 (UTC)[reply]

"Working" is a weird section title

"Working," the first section of this article after the lede, seems like a very peculiar title. I suspect it may have been written by a non-native English speaker? We don't usually use the word "working" in that way in English, nor in Wikipedia. I'm not quite sure what it should be: "Workings" (as in "inner workings of"), "How it works", &c. seems possibilities.

But maybe the section heading should be removed and its contents promoted up one level of the hierarchy? Thoughts/suggestions? jhawkinson (talk) 00:59, 23 December 2023 (UTC)[reply]
