Eli5. Why does the top part of a blender where it only spins whenever the motor spins gets so hot whenever you turn on the blender

Question

I’m not talking about the motor. I’m talking about the other part where you put liquids.

Answer 1

For the blades to spin, there has to be a connection between the motor that is outside the pitcher and the blades inside the pitcher. Obviously this connection needs to be water tight. To make it water tight, there is a seal on the bottom of the pitcher that squeezes against the spinning shaft that connects the motor to the blades. Especially when the blender is empty and dry, there is a lot of friction on the seal so it generates a lot of heat.
