(1) Motor; single-phase series motor for self-ventilation protection. The insulation is class E. The stator and armature wires are made of high-strength polyester enamelled round copper wires, and they have been specially insulated to ensure reliable quality. All wiring uses an exceptional structure, with excellent touch. The commutator is made of trapezoidal copper bar, with thermosetting plastic and mica sheet as the insulating medium. Thermosetting engineering plastics are pressed between the electrode shaft and the iron core. The casing and handle cover of the 6, 10, 13 mm electric drills are made of thermoplastic engineering plastics. The 19, 23 mm electric drills are equipped with plastic bushings in the aluminum shell to form two layers of insulation structure.

(2) Switch: The electric drill switch with hand-press quick blocking and self-locking equipment is selected.

(3) Capacitor: A capacitor is installed in the handle of the anti-disturbance electric drill, which can suppress the disturbance of infinite power and TV.
