Articles on Synchronous Motor



As there in no constructional difference between dc generator and dc motor, similarly there is no difference between the construction.....


A device which converts an electrical energy into a mechanical energy running at synchronous speed is called as Synchronous Motor. Its speed is constant.....


A device which converts an electrical energy into a mechanical energy running at synchronous speed is called as Synchronous Motor. Its.....


When synchronous motor is loaded, its rotor falls back in phase by the load angle ' α '. When load increases slowly, angle ' α ' also increase so.....


If Synchronous motor is on no-load and over excited ( Eb  >  V ) then the current drawn by it leads the voltage by nearly 90°. This is shown in the.....


When the three phase uniformly distributed winding suitably wound on the stator is supplied with 3-φ a.c supply, a rotating magnetic field of constant.....


When synchronous motor is loaded and load is kept constant, the input power drawn by motor will remain constant i.e., √3 V I Cos φ is.....


In synchronous motors performance characteristics obtained by v-curves and inverted v-curves. Synchronous machines have parabolic type.....


Let,V = Supply voltage / phase, Ia  = Armature current / phase, Ra  = Armature resistance / phase, α = Load angle, φ  = Power factor angle.....


Synchronous impedance may be defined as the vector sum of the armature resistance and synchronous impedance.....


Difference Between Induction Motor and Synchronous Motor
