  1. 16. Electromagnetical model of an induction motor in COMSOL Multiphysics

    University essay from KTH/Elektrisk energiomvandling

    Author : Viktor Wilow; [2014]
    Keywords : Electromagnetical model; Induction motor; Finite element method; COMSOL Multiphysics;

    Abstract : Ansys, Flux or COMSOL are examples of software-tools that can be used to study magnetic noise, caused by magnetic forces in the air-gap, in induction motors. The project team wanted to use COMSOL in this thesis. The electromagnetical domain needs to be coupled to the mechanical domain to complete the study. READ MORE

  3. 17. Electric Motors for Vehicle Propulsion

    University essay from Fordonssystem; Tekniska högskolan

    Author : Martin Larsson; [2014]
    Keywords : electric motor; vehicle propulsion; efficiency map; DC; induction; permanent magnet; switched reluctance;

    Abstract : This work is intended to contribute with knowledge to the area of electic motorsfor propulsion in the vehicle industry. This is done by first studying the differentelectric motors available, the motors suitable for vehicle propulsion are then dividedinto four different types to be studied separately. READ MORE

  4. 18. Non-Invasive Technologies for Condition Monitoring of Synchronous Motors

    University essay from Elektricitetslära

    Author : John Sjölander; [2014]
    Keywords : Condition Monitoring; Co-simulation; Synchronous Motors;

    Abstract : The modern industry today is highly dependent on electric motors of differenttypes and sizes. Synchronous motors are used in applications where a fixedspeed is desired. These machines are often found in high power applicationswhere they are preferred over induction motors due to their higher efficiency. READ MORE

  5. 19. Predicting Electromagnetic Noise in Induction Motors

    University essay from KTH/Numerisk analys, NA

    Author : Minh Khoa Nguyen; [2014]
    Keywords : ;

    Abstract : Induction motors are used in many applications, especially in our daily modes of transportation such as trains, cars, buses, trucks, etc. As a consequence, they contribute a significant amount of noise in the environment, which can cause serious problems on the human well-being.

  6. 20. Reducing Pumping Related Electricity Costs - A Case Study of Three Water Utility Companies in Zambia : Energy Efficiency in Pumping

    University essay from KTH/Energiteknik

    Author : Bennet Siyingwa; [2013]
    Keywords : Pumping costs; Pump Rehabilitation; Energy Audits; Reducing Electricity Costs; Pumping; Energy Efficiency; Pumping Infrasturcture; Centrifugal Pumps; Induction Motors;

    Abstract : Electric pumps are extensively used in many industrial and commercial applications worldwide and account for about twenty percent of the world’s electrical energy demand. The useful energy consumed by the pumps is less than what they demand due to inefficiency caused by a number of reasons including the mismatch between the rated operating conditions and their actual operating conditions.
