The invention discloses a two-in-one permanent magnet synchronous traction machine special for an elevator, which overcomes the problem that the traditional elevator traction machine in the prior art is of a structure of a motor and a reduction gearbox and is relatively large in size, and comprises a control system, a traction system, a traction system, a traction system and a traction system, and is characterized in that the control system realizes real-time control on a permanent magnet synchronous motor through a magnetic railing ruler, an encoder and a frequency converter; the permanent magnet synchronous motor is located in the planetary gear speed reducing mechanism, provides power for the planetary gear speed reducing mechanism and drives the planetary gear speed reducing mechanism to rotate; the planetary gear speed reducing mechanism is located in the traction wheel and used for reducing the speed of the power provided by the permanent magnet synchronous motor and transmitting the power to the traction wheel; and the traction wheel receives the power decelerated by the planetary gear retarding mechanism and drags the steel wire rope to drive the elevator car to move up and down. A planetary gear reducing mechanism is added, so that the rotating speed of the motor is increased; the planetary gear speed reducing mechanism and the motor are installed in the traction wheel, space is saved, meanwhile, the outer diameter of the motor can be reduced, and efficiency and power density can be increased.
