Study Committee Introduction
2
Scope
Study Committee A1, dealing with Rotating Electrical Machines,
facilitate and promote the progress of engineering and the
international exchange of information and knowledge in the field of
electrical rotating machines by means of synthesizing state-of-the-
art practices and developing new recommendations;
SC A1 is active in the areas of Turbo-Generators, Hydro-Generators,
Large Motors, High Efficiency Motors and New Technologies
Material presented by Canadian representative or delegate.
Strategic Direction
Create greater awareness of study committee activities in Canada
Generate interest and promote Study Committee work
Involve a broader audience
Objectives of the
study comittee
Strategic Direction
SC A1 has 24 regular members, 13 observer members, 8 technical
advisors, chairman and secretary and around 309 experts from 41
countries contributing to A1 activities and attending A1 meetings
and colloquiums. Members of our Study Committee are from
Utilities, Manufacturers, Consultants, Research Centers and
Universities;
The activities of the Study Committee have been driven by the
following six key main Strategic Directions:
SD 1: Asset Management
SD 2: Machine/System Interaction
SD 3: Renewable Generation
SD 4: Large Motors
SD 5: Machine Monitoring, Diagnosis and Prognosis
SD 6: Efficiency of Electrical Machines
