SUMMARY

Superconducting motors and generators enhance performance by utilizing superconductors to expel magnetic fields, thereby generating Lorentz forces in motors and induced EMF in generators. The discussion highlights the potential of superconducting windings to create stronger magnetic fields, which, when combined with superconducting rotors, can lead to increased torque and speed due to higher currents. Numerous resources, including articles and studies, confirm the viability and benefits of superconducting electric machines.

How can superconductors improve motor/generator's performance?

A superconductor will expel a magnetic field, how can it generate a Lorentz force in the case of a motor, and a induced EMF in the case of a generator?

It's makes sense that we can only improve the windings of the electromagnet, to make it superconducting generating higher fields. But what about the rotor of a motor if it's a superconducting... having higher currents would lead to greater torques & speeds,due to the combination of a stronger field & higher current?

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
