Guiding and shunting structure of generator motor rotor magnet yoke

The invention discloses a guiding and shunting structure of a generator motor rotor magnet yoke. The guiding and shunting structure is composed of a magnet yoke assembly, a slotless magnet yoke forging, a slotted magnet yoke forging, a ventilating slot, a screw, a nut and a magnetic pole. The structure is composed of a guide shunt block, a magnet yoke bypass air duct, a magnet yoke main air duct,an excitation coil, an excitation coil bypass air duct, an excitation coil main air duct and a key. According to the structure, the cooling problem of the rotor of the high-capacity and high-rotating-speed generator motor is effectively solved, and the cooling structure of the rotor is simple and reliable through the design of the magnet yoke air duct structure. The air volumes of the bypass air duct and the main air duct can be distributed by adjusting the structural size of the guide air flow block, so that the convective heat exchange capacity between air and a rotor heating part is enhanced, and efficient cooling
