Exports China Electric Tools Motor, power tools are generally DC motor, electric vehicles are generally permanent magnet motor.This difference is the result of marketization.To put it simply, the two products have different requirements for driving motors, leading to different motor selection. Power tools require motors to be low-cost solutions with simple control and low requirements for space and weight. DC motors are the first choice.In addition to the cost, electric vehicles also have high requirements for energy density (save cabin layout space, lightweight vehicle) and high requirements for performance control, so the current permanent magnet motor is the first choice.With the progress of science and technology, there are also a lot of electric screwdrivers on the market at present, positioned in precision instrument maintenance, gear adjustment function can be adjusted according to the need to adjust the torque, adapt to the maintenance needs of precision instruments, while not causing damage to the screws.But these electric screwdrivers have a drawback.Change the speed reduction ratio and adjust the input speed and torque of the gearbox according to the design requirements of the electric screwdriver.Compact structure, high efficiency, realize the tightening function.Speaking of electric screwdriver, I believe that many electric enthusiasts and digital enthusiasts are familiar with.The size of the electric screwdriver is much smaller than that of a traditional cordless electric screwdriver compared to a pen.Whether corded or wireless, today's power tools offer greater power (torque) in smaller, lighter models.Ergonomic considerations make today's electrodynamic screwdrivers easier to use and safer.
