What is the role of fingerprint lock motor? What are the components of the fingerprint smart lock motor? Introduction to motor components in smart door locks. In the internal structure of the smart lock, the motor is an integral part of the whole, and it is the core part of unlocking and locking. So, what precautions do many manufacturers make when selecting motors? Let's take a look at the smart lock motor video tutorial and component function introduction, together with the motor mechanical construction drawing!
Fingerprint smart lock motor video introduction
Tips: Since the fingerprint smart lock motor is a miniature motor, it is not suitable for display. Here a DC motor of the same principle is provided as a video reference.
What is the function of fingerprint smart lock motor?The motor is a driver. Just like the computer's driver software. It is the connecting device of electronics and machinery. It is the transforming center of power and plays a major role in the connection. If the motor stops working or an obstacle, the lock will automatically open and cannot be locked.
An intelligent door lock motor is a miniature motor, which is composed of a housing, a copper wire, a coil, and a magnet as a common motor. The general smart door lock motor is a DC motor. The outer shell is made of galvanized steel and the inside is wrapped with copper wire.
It consists of a stator and a rotor with a certain air gap between them. The main feature of its construction is that it has an armature with a commutator.
The stator consists of a frame, a main magnetic pole, a commutating magnetic pole, a front and rear end cover, and a brush holder. The main magnetic pole is the main component that generates the air-gap magnetic field of the DC motor, and consists of a permanent magnet or a laminated core with a DC excitation winding.
The rotor consists of armature, commutator (also known as commutator) and shaft. The armature consists of an armature core and armature winding. The armature iron core is formed by stacking silicon steel sheets, and the tooth grooves are evenly distributed at the outer circumference of the armature core. The armature windings are embedded in these grooves. The commutator is a mechanical rectification component. After being stacked into a cylindrical shape, the commutator piece is formed into a whole body with a metal clip or plastic. The commutator segments are insulated from each other. Commutator quality has a great influence on operational reliability.
Smart door lock motor is a self-controlled variable frequency permanent magnet synchronous motor, in terms of its basic composition. It can be considered as a "motor system" composed of a motor body, a rotor position sensor, and an electronic switch circuit.
The motor performs operation. At this time, the cardholder can open the door by gently pulling the door lock handle. In other words, the inside motor is used to open the door.
Scope of application: electronic door locks, security monitors, beauty equipment, medical equipment, optical equipment, robots, electronic equipment, smart printers, high-end toys, stage lighting.

The motor inside the smart door lock lock does not reset several possible causes:
1, can not be reversed positive rotation, circuit board components have problems, need to replace the motherboard, or the pressure switch behind the lock tongue break, resulting in the chip can not read the tongue out of the information.
2. If it cannot be switched at all, it may be a fault in the motor connection. It is necessary to check the motor connection or the motor is damaged by aging.
3, the guide plate spring breaks, resulting in the failure to retract after the top of the refurbishment, leading to the illusion that it can not be reversed.
4. In the mechanical part, check the empty seat (handle free body) in the lock body. Sometimes the square shaft is too long or squeezed too tightly, which will cause the disengagement card to die in the empty seat, resulting in no retraction. These are the methods that are frequently used when the author is at the hotel.
However, there are too many types of smart locks on the market, and the specific manufacturer of the product must contact you.
Fiber Optic Light kits comes in two configurations -single sheathed or unsheathed strands of 0.25mm, 0.50mm, 0.75mm, 1mm, 1.5mm,2mm or 3mm diameter fibre, or as multiple sheathed strands of 0.75mm,1.0mm fibre.
Single strands of fibre give starry points of light and normally require no termination, whilst multi-stranded varieties are normally terminated with a ferrule to allow the attachment of an end fitting.
