The word "windings" is correct and usable in written English.
It is a noun that refers to the coils or turns of rope, wire, cloth, etc., or the bends of a road or river. For example, "The windings of the river created the perfect spot for fishing."
One advantage of the synchronous motor is that the magnetic field of the machine can be produced by the direct current in the field winding, so that the stator windings need to provide only a power component of current in phase with the applied stator voltage i.e., the motor can operate at unity power factor.
An alternative means of providing a rotating field for starting is to use two stator windings, as in the figure, where the auxiliary winding b-b′ is made of more turns of smaller conductors so that its resistance is much larger than that of winding a-a′.
Remy, for example, invented a new stator-winding design that uses rectangular wire, rather than round wire, with windings that are arranged in multiple layers.
With an alternating current now circulating within it, the rotor creates a rotating magnetic field of its own, which proceeds to chase the stator's rotating field causing the rotor to spin in the process and generate torque.Modern AC induction motors usually have three (or more) sets of stator windings, which smooths things out and allows more torque to be generated.
The rotor attempts to align itself to the flux in a way that reduces reluctance to a minimum, and that causes it to turn.The control system, however, constantly anticipates the rotor's movement and switches the current between windings so as to stop the rotor settling into its preferred alignment.
The motor works by the periodic reversal of the current running through these windings.
Current is fed to these windings on the say-so of the control system, generating flux.
And iron, a material that is nice and cheap, has very low reluctance.Inverto's reluctance motor has a rotor made of iron sheets, while the inside of the stator is covered with copper windings.
Over the past year the price of neodymium has quadrupled as electric motors that use permanent magnets instead of electromagnetic windings have gained even wider acceptance.
An alternating current applied to the stator's windings creates a rotating magnetic field, while simultaneously inducing a current in the separate conductors surrounding the rotor.
The rotor, which turns inside that casing, is surrounded by copper windings that act as electromagnets.
