The invention provides a method for reducing the explosion of welding points of a winding at an armature commutator end and risers. After the winding at the armature commutator end and the risers are welded, cushion blocks which are expanded and plugged between the risers are 0.5mm-1.5mm higher than the risers; the peripheral surfaces of the risers are coated with room temperature epoxy glue; the risers are bound with weftless tapes; an armature is erected, the axial welding points of the risers and the winding at the armature commutator end are coated with the room temperature epoxy glue; and the armature is vertically impregnated in an insulating paint and is vertically baked and cured. The application of the method can greatly reduce the probability of an explosion accident at the welding points of the winding and the risers in the using process of the armature.
