Is there an air duct inside the motor? How to reduce the temperature?

There are air ducts inside the large motor to cool down through heat exchange!

Small motors rely on fan blades to dissipate heat outside, larger motors have centralized air ducts, and larger motors are water-cooled.

Inside the large motor, there are fan blades at the front and rear of the rotor, and an air duct between the stator and the casing, which allows the heat inside the motor to flow and dissipate through the internal wind pressure. There is also water cooling, some immerse the motor in Freon liquid, and other small motors rely on external fans to dissipate heat.
