The poles can be varied at a ratio of 1:2 and thus the speed can be varied at 2:1. [ 7 ] [ 8 ] [ 9 ] Normally, the electrical configuration of windings is varied from a delta connection (Δ) to a double star connection (YY) configuration in order to change the speed of the motor for constant torque applications, such as the hoists in cranes .

Although the LWF program called for a structural life of 4,000 flight hours, capable of achieving 7.33 g with 80% internal fuel; GD's engineers decided to design the F-16's airframe life for 8,000 hours and for 9-g maneuvers on full internal fuel. This proved advantageous when the aircraft's mission changed from solely air-to-air combat to ...

The modified F-16 demonstrated a maximum speed of Mach 2.0 (Mach 2.0 is the F-16's clean certified maximum speed) and handling characteristics similar to a normal F-16. Subsonic specific excess power was slightly improved. The trade studies involved additional CFD, testing, and weight and cost analyses.
A DC armature of a miniature motor (or generator) An example of a triple-T armature A partially-constructed DC armature, showing the (incomplete) windings In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1]
(The Center Square) – Business owners from historically disadvantaged communities in Pennsylvania will soon have access to special grants meant to assist with start-up and expansion costs. For ...
Next the pins are inserted into the stator stack. The insertion process is limited by overlaps in the winding head geometry. The hairpins are usually pre-assembled in an assembly nest. [11] Individual pins are arranged in accordance with the winding scheme. In general, a single hairpin stator uses 3-16 different hairpin geometries. [12]
