Abstract

The invention discloses an elevator traction machine. The elevator traction machine comprises a machine base, a stator arranged in the machine base, a rotor cooperating with the stator, a traction wheel and a rotating shaft, wherein one end of the rotating shaft is connected with the rotor, the other end of the rotating shaft is connected with the traction wheel, the end face, far away from the traction wheel, of the rotor is provided with fan blades, one side, far away from the traction wheel, of the machine base is provided with a connecting plate, and the connecting plate is provided with aventilation opening used for allowing air flow to be in and out. According to the elevator traction machine, the structural design is reasonable, the fan blades are arranged on the rotor, so that when the rotor rotates, the fan blades rotate together to stir air inside the traction machine, the air replacement of between the inner part and the outer part of the traction machine is increased, coldair from the outer side is continuously introduced, hot air inside the traction machine is discharged, then heat in the traction machine is taken away, the temperature in the traction machine is reduced, the purposes of dissipating the heat and reducing the winding temperature rise are achieved, and the efficiency of a motor is improved.

Description

technical field [0001] The invention relates to the technical field of traction machines, in particular to an elevator traction machine capable of rapid heat dissipation. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, elevators have become an indispensable part of daily life, and the quality requirements for elevator components are getting higher and higher. [0003] At present, the heat dissipation of the traction machine mainly depends on the natural heat dissipation of the outer surface of the machine base and the rotor exposed to the air. The internal hot air cannot be actively discharged to the outside of the casing, resulting in an excessively high internal temperature, which in turn leads to an increase in the winding resistance. Consumption increases, motor efficiency is low, and power resources are wasted. Contents of the invention [0004] In view of this, in order to overco...
