After the vending machine motor drive is finished, the screw hole should be covered with a hole distance of the base nine, and it can be matched tightly, and then use the screw to hold it. As for the choice of screws, the foot hole of the motor is generally slightly larger than the normal screw, for example, a motor like 3kw can generally use ten screws.

Of course, you can also measure the hole in the bottom corner of the motor, as long as the screw is slightly smaller than the hole, of course, you must also determine the length of the screw according to the position you install, and it is appropriate to tighten the nut handle. The iron core is magnetized by the magnetic field of the energized solenoid. The magnetized core also becomes a magnet, so that the magnetic properties of the solenoid are greatly enhanced due to the superposition of the two magnetic fields.

In order to make the motor housing more magnetic, the iron core is usually made into a hoof shape. The commutation impact is large, and the temperature rises during working (the shell is equipped with heat dissipation ribs); When the valve core is stuck, the solenoid is easy to burn out due to excessive current, and the reliability is poor, so the switching frequency is not allowed to exceed 30 times/min, and the life is short.
