Synchronous motor is one of the most efficient motors. the ability to control their power factor makes it very demandable especially for low speed drives. this post will discuss synchronous motor, its construction, working principle, types, characteristics, starting methods, applications, model phasor diagram, advantages and disadvantages.
Synchronous motor and induction motor are the most widely used types of ac motor. 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.

Principles of operation of synchronous machines the synchronous electrical generator also called alternator belongs to the family of electric rotating machines. other members of the family are the direct
Thus the rotor rotates in the same direction as that of stator flux to minimize the relative velocity. however, the rotor never succeeds in catching up the synchronous speed. this is the basic working principle of induction motor of either type, single phase of 3 phase. synchronous speed
Work. there are many different electrical motors, but this thesis and the course that was made, focus mostly on the ac induction motor. the ac induction motor is the most used electrical motor in industrial applications worldwide. other motors that are included are 1
This cycle continues as conductor rotates at a certain speed. so if we plot the magnitudes of the induced emf against the time, we get an alternating nature of the induced emf shown figure above. this is the working principle of synchronous generator or alternator.
This motor has the unique characteristics of operating under any electrical power factor. this makes it being used in electrical power factor improvement. principle of operation synchronous motor. synchronous motor is a doubly excited machine i.e two electrical inputs are provided to it.
Hysteresis motor a hysteresis motor is a synchronous motor with a uniform air gap and without dc excitation. it operates both in single and three phase supply. the torque in a hysteresis motor is produced due to hysteresis and eddy current induced in the

Synchronous motors synchronous motors usually run at synchronous speed ns120fp, the synchronous motor speed is constant regardless of the load or 3
A synchronous motor is a constant speed ac motor. it takes ac power by the stator from mains supply for its working in addition it utilizes a small amount of dc power which is fed to its rotor, we need two kinds of power sources that is one is ac and another is dc as shown in the fig below.
