Chris got me thinking about motors in another post
But if the voltage and current go down, so does the power and the amount of torque developed.
If the torque demanded of the motor remains the same, then wouldn't the current increase when the voltage drops?
I agree that a DC motor will draw less current with less voltage especially without a significant load on it.Chris;
We are talking about AC loads here driven by a transformer so the DC point is sort of moot.
Since you brought it up, ...I've always consider all motors it to be more inductive than resistive for the simple fact that the motor windings create magnetic fields where energy is stored.
Wouldn't a DC motor still draw more current (creating heat) trying to drive/maintain the same load at a lower voltage?
