Variable frequency motor convenient for heat dissipation

The utility model discloses a variable frequency motor convenient for heat dissipation, which comprises a motor mounting seat, a variable frequency motor shell is fixed on the end face of the motor mounting seat, and a ventilation dustproof plate is fixed inside the right side of the variable frequency motor shell. The rotating shaft is driven to drive the heat dissipation fan blades to rotate at a high speed to generate suction force, so that external cold air can be sucked in, and the cold air enters the variable frequency motor shell through the combination of the annular air inlet screen plate and the dustproof air inlet screen plate, so that the heat dissipation effect on the interior of the variable frequency motor is realized; the problem that the variable frequency motor frequently breaks down due to the high temperature of the stator and the rotor is avoided, heat, sucked out from the interior of the variable frequency motor shell, of the heat dissipation fan blades can be rapidly discharged through
