Comparison of water pumping between pump driven by wind mill and electric motor into Brazil
(2014-04-01)
The proposed work consists in the comparison of the application of two systems for the pumping of water. With a pump drive by electric motor and the other by wind mill, in order to demonstrate the efficiency and pay-back ...
Rebobinadora elétrica com ajuste de velocidade e contagem do número de voltas
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Manutenção IndustrialUTFPR, 2015-06-15)
One of the greatest difficulties found in rewinding electric motors is the expertise of professionals that know such a procedure. Rewinding is widely used because it leads to low maintenance costs and because it is not ...
A Study of Influence of Configurations of the Windings on the Performance of Single Phase Induction Motor with Capacitor Start
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
The single phase induction motors needs two stator windings to produce rotating magnetic field : one main winding and the other auxiliary winding. The aim of the auxiliary winding is to create the rotating electromagnetic ...
Proposta de uma metodologia de rebobinamento para converter motor de indução trifásico em monofásico
(Universidade Estadual Paulista (Unesp), 2015-02-13)
This paper proposes the conversion of a three-phase induction motor into single phase through rewinding its stator. It presents a methodology to calculate this rewinding process considering the constructive parameters of ...
