A winding engine is a stationary engine used to control a cable, for example to power a mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as winding engines. Early winding engines were hand, or more usually horse powered. [1]
A winding on a motor or generator to improve commutation at heavy load. computed tomography Production of images of a cross-section through an object by multiple X-ray measurements processed in a computer. computer engineering The profession of designing computers. computer hardware That part of a computer system with physical existence.
A drum hoist (steel wire rope visible) and motor. In underground mining a hoist or winder [1] is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), although modern large hoists use alternating current drives that ...
When the stem is pushed in, a lever slides the clutch out, and the outer set of teeth engages a small wheel train which turns the mainspring arbor, winding the mainspring. When the stem is pulled out, the clutch slides in, and the inner teeth engage another wheel, which turns the hour wheel in the motion work, turning the watch's hands.
The primary winding carries the low voltage battery current, and the secondary winding generates the high voltage for the spark plug. Attached to the end of the coil is an interrupter or trembler , a magnetically operated switch , which repeatedly breaks the primary current to create flux changes in the transformer needed to produce high voltage.

Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies, the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack. These copper bars, also known as hairpins ...
