    Why don't electric motors use exciter coils like generators do?

    Hi everyone, Jeff, perhaps you are seeing squirrel cage rotors, which look like they aren't really coils, but in fact are. Both single and three phase induction motors can use these kinds of rotors. I'm not aware of any externally excited AC motor other than the synchronous motor or synchronous...

    Magnetic flux in tap changing transformers

    Hi guys, Thank you both so much for your interesting responses. I have done a little more reading, and now understand the 'EMF equation of a transformer', and so can indeed see that by reducing the number of primary turns we have increased the maximum flux. I find this quite interesting, as...

    Magnetic flux in tap changing transformers

    Hi guys, Non engineer here trying to understand an engineering principle. I think I must be going wrong somewhere in my thought process. 1. Faraday tells us that the EMF generated in the secondary of a transformer is equal to the change in magnetic flux divided by the change in time. 2. The...

    Exploring Power Networks and Electricity Generation: A Scientist's Introduction

    Hi guys, new member here so just introducing myself. I hope to be able to contribute to discussions surrounding power networks and electricity generation, and hopefully interest some of you guys in some probing discussions! I currently work as an operator in a power station.
