The invention relates to a double-stator-coil traction machine. The traction machine is provided with a rotating main shaft. A traction wheel is arranged at the front end of the rotation main shaft. A rotor is connected to the rotation main shaft. A left stator coil and a right stator coil are arranged at the bottom of the rotor. An overhead wheel and a counterweight wheel are arranged on the left side and the right side of the traction wheel respectively. A steel wire rope is connected with the overhead wheel, the traction wheel and the counterweight wheel in sequence. The bottom of the overhead wheel and the bottom of the counterweight wheel are fixedly connected with a lift car and a counterweight block respectively. The double-stator-coil traction machine has the advantages that the double stator coils are arranged in the traction machine, one or two coils can be started according to the requirement for the practical carrying capacity of a lift, so that a large amount of energy consumption is reduced, if one coil goes wrong, the other coil can still support the running of the lift, and therefore the safety of the lift is greatly improved. The double-stator-coil traction machine is simple in structure and convenient to operate.
