Load != resistance?

Question

Electronics

Explain the difference between load and resistance? This is the same? If so, then take a motor that has a rated current consumption during idle rotation, if you start squeezing it with your hand, then the current starts to increase, everything heats up and the source burns out, but the resistance has increased, so the current should fall. If not, please explain what it is.

Answer 1

How you cleverly connected the mechanical resistance to rotation with the resistance to current. Only wrong.
If we take a DC motor, a collector type (the simplest option), then at idle the windings in the motor are switched at a certain speed. As soon as you put a load on the motor shaft, the switching speed of the windings will drop. Given the inductive nature of the winding (it's a coil, isn't it?), the current in the coil increases gradually. That is, the lower the engine speed, the more current passes through the motor windings. If the motor stops at all, part of the windings turns into a constantly on heater. And the windings are not designed for the constant passage of current through them.

Answer 2

In electric motors, the current is proportional to the torque, so when you brake the motor shaft, the torque increases and therefore the current.
