ELECTRICAL MACHINE DESIGN SYNCHRONOUS GENERATOR
An electrical machine is a device that converts mechanical energy to electrical energy or viceversa, and changes alternating current from one level to another level. The machine which produces three-phase power from mechanical power is called an alternator or synchronous generator. An alternator works on the fundamental principle of ...

Answer.4. Always Star connected. Explanation. Alternators are connected primarily in the star to achieve the following motives: More economical:-The phase voltages in star connection are 57.7 % of the line voltages, i.e. the armature winding in star connection is less exposed to voltage as compared to the delta connection which in turn prove more economic if we consider insulation, breakdown ...

Construction of Synchronous Motor | Electrical4U
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.

Construction of Synchronous Reluctance Motor
The efficiency of a reluctance machine may be higher than an induction motor because there is no rotor copper loss. Because of inherent simplicity, robustness of construction and low cost. The synchronous reluctance motor has no synchronous starting torque and runs up from stand still by induction action. There is an auxiliary starting winding.
