る。Next, the operation will be explained. Heat is generated when current flows through the stator coil (2), and this heat is conducted to the stator core (1) via the ground insulation material wrapped around the outer circumference of the stator coil (2). This generates a heat flow in the stator core, but this heat is cooled by the axial cooling air holes (8) provided in the stator core (1).

る。Next, the operation will be explained with the arrow A of the zero rotor core (2).
Rainbow stator core (1) and rotor core (2) in the direction of rotation
A swirling flow B is generated due to the viscosity of the fluid in the air gap (2) between the two, and this swirling flow generates pressure due to centrifugal force. Using this pressure, the stator coil (2)
The same ventilation duct? Form a forced flow like arrow 0 at υ,
This ventilation provides effective cooling.
