Questions about motor current consumption

[little_carlos]

Hey guys
Ive been wondering, how or why the current that a motor takes increases with the amount of load taken by the motor?
i mean, is there a magnetic consumption or something? how do this works?

Basically a motor turns electrical energy into mechanical energy.
Or where did you think the mechanical energy came from?

Spinning motor generates a back EMF from the coil moving in a magnetic field ( basic electromagnetism) and as you load it the speed drops, so the back EMF drops and the opposing voltage drops so more current can flow in the motor, limited by the resistance. This increased current provides the force turning the coil so it provides more torque till the torque into the load equals the power applied.
