The invention provides a wire-drawing device of a stator coil of a motor, and relates to the technical field of removal of mining explosion-proof motor stator coils. The device comprises a support frame, a heating portion, a moto clamping portion and a withdrawing portion, the support frame comprises a chassis, a support rod vertically fixed at one side of the chassis, a motor fixing disc arrangedabove the chassis, and an upper support arm arranged above the motor fixing disc, the heating portion comprises a first telescoping cylinder vertically fixed on the chassis, a lower cover is fixed atthe top end of the first telescoping cylinder, a preset number of electric heating rods are vertically fixed on the lower cover, the withdrawing portion comprises a third telescoping cylinder vertically fixed on a lower end surface of the upper support arm, and a telescoping hook is fixed at the bottom end of the third telescoping cylinder. According to the wire-drawing device of the stator coilof the motor, the removal operation of the mining explosion-proof motor stator coils can be conveniently realized with high efficiency, and offset or damage of laminated silicon steel sheets of internal wire slots of a stator can be avoided.
