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.
The present paper attempts to develop the rotating-field theory of synchronous and induction machines as an important alternative to the 2 the general operational equations of the synchronous machine two-reaction theory.
Permanent magnet synchronous motor, pmsm is a kind of synchronous motor in which permanent magnet is used as rotor to create field poles.No field winding is wound on the rotor.Construction of permanent magnet synchronous motor pmsm the basic construction of pmsm is same as that of synchronous motor.The only difference lies with.
