As the saying goes, "if you want to be good at something, you must first sharpen it." as a mechanical component, the normal operation of the electric screwdriver cannot be separated from 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 rotation speed will be different when the power output of the electric screwdriver is the same.
BLDC36-H high-speed brushless DC motor is applied to the solution of electric screwdriver: the motor adopts bearing link, which can reduce the wear between parts, reduce noise and provide the service life of the whole machine. This high-speed brushless DC motor has the advantages of large torque, low operation and fast speed. The brushless DC motor does not produce high temperature and carbon powder in the process of use, and its performance is superior. It is especially suitable for long-term continuous use.
Components of a high-speed brushless DC motor
Basic parts: armature (rotor), motor front cover, bearing, magnet (stator), motor gasket.
(1) Armature: The most important part of the electric batch, like the "heart", the state of the armature will determine whether the electric batch can work normally. The quality of the armature: We can know by measuring its DC resistance. Under normal circumstances, the DC resistance (220V) between the adjacent two poles of the armature commutator is about 15 ohms larger (due to different manufacturers, the value is not the same, the larger DC resistance exceeds 20 ohms).
(2) The front cover of the high-speed brushless DC motor: Judging from the appearance, it is damaged.
(3) Stator: Judging from the appearance of the internal disk for damage and displacement (causing magnetic asymmetry), at the same time, a flat-blade screwdriver can also be placed inside the magnet to check the size of its magnetism. If the magnetism is too small, it should be replaced New magnets.
(4) Bearing: Judging from the rotating bearing, there is a stuck phenomenon. When the internal friction is strong, the motor crying noise is louder.
(5) Gasket: Fix the armature to prevent shaking up and down and ensure stability. The right number of spacers; the armature will not rock up and down, and the armature can be twisted with less force.
