description The utility model discloses a multispeed three-phase asynchronous motor for a tower crane. The motor comprises a main body and is characterized in that an air inlet and an air outlet are formed in the main body, wherein air inducing blades are mounted on the shaft of the main body. The multispeed three-phase asynchronous motor provided by the utility model has the benefits that the product structure is reasonable; and power generated by the motor shaft drives the air inducing blades to form negative pressure, air is induced into the motor and then exhausted, so that the interior of the motor is effectively cooled down, the temperature rise of the motor is reduced, and the equipment is protected.
