What is the principle of the electric drill?
The rotor winding single-phase electric drill motor series through the brush and the field winding phase, when AC or DC power, magnetic field and rotor winding field winding generated by magnetic interaction torque the motor rotation, and then through the deceleration gearbox, and increases the bit rotation torque.
The main components of a drill are a drill chuck, an output shaft, a gear, a rotor, a stator, a casing, a switch and a cable
Electric drill is the electric tool industry's biggest selling products, widely used in construction, decoration, furniture and so on Pan industry, opening for the object or objects in the past, also known as hammer in some industries.
A flashlight is a drilling tool powered by alternating current or direct current batteries. It is a hand-held electric tool.
The rotor winding single-phase electric drill motor series through the brush and the field winding phase, when AC or DC power, magnetic field and rotor winding field winding generated by magnetic interaction torque the motor rotation, and then through the deceleration gearbox, and increases the bit rotation torque.
