Viesturs Bražis. Asynchronous electric drive with frontal part winding
... the full supply voltage does not provide the quality starting process because motor torque and current are not restricted at all. The induction motor parametric control includes the stator voltage control during start. In the second half of 20th century this method were researched by L. Petrov [10] ...

Volume/Weight/Cost Comparison of a 1 MVA 10kV/400V
... Fig. 1(a) shows the basic schematic of a three-phase LFT in delta-wye connection. The electrical part consists of two times three copper (or aluminum) windings and a magnetic core, which is usually made of low-loss silicon steel laminations. While dry-type solutions are available, distribution trans ...

Final Report - Senior Design
... Centerville, Iowa, currently has a systems using UV technology with a single lamp that can only cure a small area roughly 16 inches in diameter. The goal of this project is to expand upon this system to cover a much larger area. The proposed final area is to be 3 to 4 feet on each side. This report ...

... Since the speed of sound varies with altitude and atmospheric conditions, a calibration mode is quite useful. Our program is designed such that if in calibrate mode, the user can place the device a known distance 5 centimeters and send a pulse. The device then uses the time necessary for the pulse ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
