Best Selling Impact Screwdriver Power Tool Electric Tool Drill Electric Screwdriver

As a mechanical part, the electric screwdriver can not work normally without the power supply of the electric screwdriver, which provides energy and related control functions for the electric screwdriver. Drive the motor to rotate. Because the parameters of the electric screwdriver motor are different, the speed will be different when the power supply of the electric screwdriver outputs the same power.

Single phase series motor with commutator and DC motor will cause serious electrical interference to TV and radio, so the interference of tilting system to radio shall be considered in the design of electric screwdriver. Measures such as shielding, symmetrical connection of exciter windings, setting of electrical filters, and connection of filters into △ shape are mainly adopted. If necessary, small inductance coils can also be connected in series at both ends of the motor armature.
