THEORY, CONSTRUCTION, AND OPERATION

PART ITHEORY, CONSTRUCTION, AND OPERATION1 CHAPTER 1 PRINCIPLES OF OPERATIONOF synchronous MACHINESThe synchronous electrical generator (also calledalternator) belongs to thefamily of electric rotating machines. Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a numberof derivatives of all these three. What is common to all the members of this fam-ily is that the basic physical process involved in their OPERATION is the conversionof electromagnetic energy to mechanical energy, and vice versa.

Python is an interpreted language, which means you just type in plain text to an interpreter, and things happen. There is no compilation step, as in languages such as c or FORTRAN. To start up the Python interpreter,just type python from the command line on climate. You’ll get a prompt, and can start typing in python commands.

Construction of synchronous machines The rotor of a synchronous machine is a large electromagnet. The magnetic poles can be either salient (sticking out of rotor surface) or non-salient construction. Non-salient-pole rotor: usually two- and four-pole rotors. Salient-pole rotor: four and more poles.

synchronous motor has a synchronous reactance of 1.95 ohm/phase. Compute the max. torque in N-m which this motor can deliver if it is supplied from a constant frequency source and if the field excitation is constant at the value which would result in unity power factor at rated load. Assume that the motor is of cylindrical rotor type.
