Wrap a synchronous method in Asynchronous call c#

I am looking to wrap synchronous methods into asynchronous code in order to expose those methods as asynchronous - the reason is I do not want to duplicate the code inside the synchrnous methods as I would like it to be DRY and already knowing the functionality of the syunchronous code works - no need to manage separate method as well.

What are the industrial applications of synchronous machines?

May 14, 2018  Large synchronous motors are often used in the mining industry to run mills. These applications tend to span from about 400Hp (300kW) to twin 7,000Hp (5.2MW x 2). As someone else noted, by over-exciting the field windings of these motors, they can...

Belts and Pulleys - Motion Control Tips

Minimum wrap angle is a measure of how much the belt wraps around the smallest pulley. Belt length is how long the belt would be if cut and laid flat. Finally, in the case of toothed belts (also called synchronous belts) the pitch is the number of teeth per some length—so a 3-mm pitch means that the belt has one tooth every 3 mm, for example.

Field coil - Wikipedia

A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator.It consists of a coil of wire through which a current flows. In a rotating machine, the field coils are wound on an iron magnetic core which guides the magnetic field lines. The magnetic core is in two parts; a stator which is ...

Synchronous Motors: Applications And Working Principle

Jul 11, 2019  Synchronous motor finds application where operating speed is less (around 500 rpm) and high power is required. For power requirement from 35 kW to 2500 KW, the size, weight and cost of the corresponding three phase induction motor is very high. Hence these motors are preferably used. Ex- Reciprocating pump, compressor, rolling mills etc.

Synchronous motor - Wikipedia

A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line ...

AC Synchronous Motors Kollmorgen Synch Motors ...

AC synchronous motors are the workhorses of industry. With synchronous motor technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply use gearing or a belt- or chain-drive ...

How does synchronous motor work? Yahoo Answers

Jul 11, 2009  Simplest synchronous motor: The stator is an electromagnet, fed with alternating current. The armature is a permanent magnet. The polarity of the stator reverses in time with the supply current, thus alternately attracting and repelling the armature. The speed of the motor depends on the frequency of the supply current.
