Permanent magnet DC motors are similar to normal DC shunt motor, the only difference is that they consist of permanent magnets for producing magnetic flux instead of stationary field winding. By the interaction of flux produced by permanent magnet and armature current, the torque is developed in motor.
READ MOREThis does three things. First, since the permanent magnet is lossless it eliminates the energy required for excitation, usually improving the efficiency of the machine. Second, since eliminating the excitation loss reduces the heat load it is often possible to make PM machines more compact.

READ MOREDC generators are classified based on how their fields are excited (i.e. produced). There are three methods of excitation, and thus three main types of DC generators: Permanent Magnet DC Generators – Field coils excited by permanent magnets. Separately Excited DC Generators – Field coils excited by some external

READ MOREThe synchronous generator is such a device that transforms mechanical energy into the electrical energy delivered by the prime mover of the generator. It is also known as an alternator. It is called a synchronous generator because its rotation speed is equal to the rotating speed of the field at the stator of the generator called synchronous
