| 英文摘要: |
| To address the problem of poor heat dissipation in the axial ventilation holes of the rotor of the current AC traction motor, a
new axial ventilation slot structure is proposed for the teeth of the rotor. According to this distribution diagram, a new rotor teeth axial
venting slot structure is proposed for the problem of high temperature of the rotor end rings and teeth; the influence of the new venting
slot structure parameters on the motor rotor heat dissipation effect and the motor related performance indexes is analyzed, and a new rotor
teeth axial venting slot structure is proposed. The results show that the proposed new rotor teeth axial venting slot structure significantly
reduces the temperature of the rotor teeth and end rings compared to the traditional axial venting slot structure, while keeping the motor
performance indexes basically unaffected, thus significantly reducing the temperature of the rotor teeth and end rings. It improves the
ventilation and heat dissipation effect, which is important for reducing the total body temperature rise of the motor and thus extending its
service life. |
