When a motor is coasting to standstill, if I apply a DC voltage across the windings I will brake that motor... We'll at least that's what I've read.
Now here's the thing. With reverse current braking I literally reverse the direction of the motor until it's at 0rpm,and then I disconnect the supply. Which is understandable. But when it comes to DC braking, I just apply the voltage across a winding, without taking current direction into consideration, and the rotor will stop. How does this happen? In fact, why does it stop to begin with?
