The goal Basic concepts of electromechanical conversion.Operating principles of DC and AC machines.Construction and connections. Dynamic model. Air gap field and calculate the torque. Analyze the steady state operation and introduce equivalent circuits and mechanical characteristics. Ability to analyze and specify AC and DC motors and generators. Review the power supply and control requirements of EM.
The outcome Introduction to the principles of electrical machines, understanding the fundamental aspects of construction machines for direct current and alternating current machines, knowledge of proper alternative scheme for the stationary state, the basic knowledge of the mechanical properties of individual machines. Acquiring skills in modeling, specification, and use of EM.
