How does a self winding clock work?
A self-winding clock works by using a mechanism that winds itself through the natural motion of the clock itself. As the clock operates, a small part of the energy produced is used to wind the mainspring, which powers the clock's movement. This eliminates the need for manual winding and ensures the clock continues running accurately.
What is the abbreviation for winding?
The abbreviation for winding is "wnd" or "wdg".
What is the advantage and disadvantage of wave winding?
Advantage: Wave winding provides a higher voltage output compared to lap winding with the same number of turns in the armature. This winding type also allows for better cooling due to the interleaved nature of the winding. Disadvantage: Wave winding is more complex to construct and repair compared to lap winding. It also requires more insulation material between the turns, which can increase the overall size of the winding.
What is the difference between a wristwatch and a stopwatch?
A wristwatch is worn on the wrist and tells the current time. A stopwatch is held in the hand, and is used to time the duration of an event. A wristwatch is always running, telling the time. A stopwatch is started and then stopped.
Which is higher run or start winding?
The run winding is typically rated to handle higher current than the start winding in an electric motor. The run winding is designed to sustain continuous operation once the motor is running, while the start winding provides the initial torque required to start the motor.

Answering Which one is a separately excited generator - ac generator or dc generator?
Excitation is the phenomenon by which you control the excitation of field winding of a generator. In DC generator field winding is placed on stator and this field winding can be self excited or seperately excited depending upon the type on generator used. AC generators can also be self excited or seperately excited type but field winding is placed on rotor nad armature winding on stator.
Where can self winding watches be bought?
Self winding watches have been around for many years. Any leading jeweler will carry different brands. Kay Jewelers, Zales, Jarrod Galleria, and The Jewel Box all have them.
