Web5 jul. 2024 · For both DC and AC drives the input current is about 100%. We now begin to reduce the speed. For the DC drive the input current magnitude remains unchanged, and we can only tell that the speed is falling if we look at its active component (in phase with the voltage). For the AC drive the input current falls, not quite proportionately to the speed. WebThe basic process of generating currents with magnetic fields is called induction; this process is also called magnetic induction to distinguish it from charging by induction, which uses the electrostatic Coulomb force. When Faraday discovered what is now called Faraday’s law of induction, Queen Victoria asked him what possible use was electricity.
