In the case of a capacitor-start motor, the main winding is the running winding and the auxiliary winding is the starting winding.
How many turns in primary winding of a welding machine?
primary winding and secondary winding how this turn.
Which winding has the higher resistance start or run in single phase motors?
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.
Are all rolex watches self winding?

What watches have self moving parts?
One type of watch is known as the "self-winding" or "automatic watch," which winds itself using the natural motion of the wearer. Movement rotates a winding rotor, which winds the watch via a ratchet. Other analog watches also bear self-moving parts, though for most this merely consists of the watch hands and associated gears.
Do clocks and watches use the same mechanism?
Clocks and watches use different mechanisms for movement. A clock uses power source, wheel train, escapement, and oscillator mechanisms. A watch uses full plate movement, three -quarter movement, bridge movement, manual or hand winding, and automatic or self winding.

No
What do the different movements of watches?
The two main categories are mechanical and quartz. Mechanical watches are split into two categories: manual and self-winding (aka automatic watch). Mechanical watches are powered by a wound spring that drives the gears. Automatic watches have a small spinning weight (called a rotor) that helps wind the spring which powers the watch. Manual watches rely on the watchwearer to wind the crown (knobs on a watch). Quartz watches are mostly powered by batteries and use the fast vibration of a quartz crystal to keep time.
