EEE :: Synchronous Motors
- In a synchronous motor it the back e.m.f. generated in the armature at noload is approximately equal to the applied voltage, then
- A synchronous motor connected to infinite bus-bars has at constant full load, 100% excitation and unity power factor. On changing the excitation only, the armature current will have
- The maximum constant load torque under which a synchronous motor will pull into synchronism at rated rotor supply voltage and frequency is known as
- Change of D.C. excitation of a synchronous motor changes
- Mostly, synchronous motors are of
- A synchronous machine with low value of short-circuit ratio has
- In a synchronous motor which loss varies with load ?
- The magnitude of field flux in a 3-phase synchronous motor
- The efficiency of a properly designed synchronous motor will usually fall in range
