All types of Motor & Generators - AC & DC‚ Starters:Induction Motor (3 Phase):The production of a rotating magnetic field (RMF) is essential for the operation of alternating current (a.c.) induction motors. The speed of rotation of an RMF is known as the synchronous speed and this will be governed by the value of the supply frequency and the number of poles wound within each phase winding. Each of the phase windings are 120 electrical degrees apart. Synchronous speed can be calculated using the following

How Humans Impact Each Cycle EVS-1001 January 23‚ 2014 Brett Pierce Abstract Humans impact to the carbon cycle with the circulation of the carbon among many living organisms and their environment as well. The carbon dioxide that is surrounded will be synthesized by the plants and their tissue that is swallowed by animals with transforming in to carbon dioxide again while living or dead. The humans affect this cycle with taking 40% from the photosynthetic effect of plants on land. Where

Laboratory No 4 Electrical Systems 100 AC CIRCUITS INTRODUCTION The purpose of this laboratory test was to make comparisons between theoretical and practical results and to develop a greater understanding of factors affecting the operation of complex AC networks. SUMMARY OF RESULTS The error in the results ranges from 0.02% to 22.63% and the phase angle errors ranged from 0.02° to 17.27°. This suggests that part of our results were very accurate (series parallel RC network) and the rest
