Synchronous motor construction and working ...
Construction of a synchronous motor is similar to an alternator (AC generator). A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.Get Price

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 nonsalient construction. Nonsalientpole rotor: usually two and fourpole rotors.Get Price
What is meant by saliency in synchronous machines? Quora
Aug 11, 2018· There are two types of synchronous machines: (1) Salient pole synchronous machines. In these machines field poles are distinctly visible. A spider is mounted on the shaft. The spider carries rotor core and poles are radially fitted onto the core. This type of construction is adopted for hydro generators which are low speed machines. Due to low ...Get Price
