value (of say 132kV to 400kV) the use of AC power has increased rapidly and the DC power is used only at remote places where AC power cannot be supplied through power lines or cables or for a few social purposes. A synchronous generator is an electrical machine producing alternating emf (Elec-tromotive force or voltage) of constant frequency.
· DC Motor Introduction, Principle and Working Introduction: DC motors are rarely utilized in normal applications as a result of all electrical supply firms furnish electrical energy but, for special applications like in steel mills, mines and electric traction, it's advantageous to convert AC into DC so as to use DC motors.
Lecture Notes Elements of Electrical Machines 12 Figure 2.3 : Torque in DC Motor Figure 4 : Current Flow in DC Motor Constructionally, there is no basic difference between a dc generator and motor. In fact, the same dc machine can be used interchangeably as a generator or as a motor. The basic construction of a dc
The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. Read: Working of DC Motor Save All dc machines …

The armature reaction in a dc generator is explained as below, Consider no current in armature conductors, then MNA coincides with GNA.. Now, when current start flowing through the armature conductors, due to the combined action of main flux and armature flux the MNA get shifted from GNA.. In case of a generator, the M.N.A. is shifted in the direction of rotation of the machine.

· The construction of a synchronous motor is very similar to the construction of an alternator. Both are synchronous machines where one we use as a motor and the other as a generator. Just like any other motor, the synchronous motor also has a stator and a rotor. We will look into the construction details of the various parts one by one in detail.

AC generators can be classified as Synchronous generators and Induction generators. There is significant difference between operating principles of synchronous and induction machines. For now, let us discuss the difference between synchronous generator and induction generator.
A DC motor is an electrical machine which converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming’s Left-hand Rule and its […]
