Performance curves means when motor performance is shown as a graph from starting of the motor to running. Generally variation of following parameters are noted at various loading of the…
Both crawling and cogging effect is only observed in squirrel cage induction motor as in wound rotor inductor motor, this effect is not observed as toque is very large. Crawling:…
Synchronous condensor is just a synchronous motor without any load , but with over excitation. Generally it is used in receiving grid electric substations to improve power factor. The synchronous…
When the motor becomes wet due to being flooded or climatic conditions or when the motor rewinding is done. It shows very low value of insulation resistance. The low value…
