Li Xinxiang Worm Gear Worm Geared Motor
For a long time, the pusher motor used in the fog machine industry has high price, high installation requirements and large installation space. Restricting the promotion of the automatic closing function of the hood, after replacing the worm gear motor,
Driving method of stepper motor driver
The stepping motor cannot be directly connected to the power frequency AC or DC power supply to work, but must use a dedicated driver, as shown in the figure, it is composed of a pulse generation control unit, a power drive unit, a protection unit and so on. The two units enclosed by the dotted line in the figure can be realized by microcomputer control. The driving unit must be directly coupled with the driver (anti-electromagnetic interference), which can also be understood as the power interface of the microcomputer controller, which will be briefly introduced here.
