Product Description

SDM-10G32/SDM-20G32 Encryption Sliding Gate Motor General Introduction:
In order to make the installation and configuration easier, we have developed this intelligent 1 button learning sliding door control board. The control board adopts advanced microcomputer chip, digital control, more practical functions, higher safety performance, easier installation and configuration. Fully compatible with the smartphone app network (WiFi/3G/4G/5G) control and bluetooth control and many other features.

Features:
1.  Anti-rush design. At the first operation after each power on, the motor runs in slow motion to the limit point throughout the process to avoid rushing out of the limit. When the door reaches the limit point, the motor can only be operated by pressing the button of the opposite direction to prevent the limit from being broken out. (Notice: It has the power off protection function when in place, and the motor only moves in the opposite direction when repowered).
2. Master-slave mode available. Two motors with the same control board on each can work synchronously. In this mode, infrared, ground sense, automatic door close and other functions are synchronized. Attention:Infrared, ground sense must be connected to the master motor.
3. Motor runtime protection. To prevent the motor from running during the travel failure, the control board will automatically learn the motor running time without manual setting, and 10s will be added automatically as the time margin.
4. Auto-close function. Time can be set from 1s to 250s before the door closes automatically. The default value is 3s.
5. Soft start and slow stop. There’re soft start and slow stop features available. The distance and speed of the slow stop feature can be adjusted.
6. Stop & rebound against resistance. Switchable between stop against resistance and rebound against resistance for the closing travel. Stop against resistance for the opening travle.
7. Onboard socket for bluetooth module. A socket is integrated onboard for the insertion of the standalone bluetooth module (module not included by default).
8. One button configuration for internet control. Can be directly paired with the internet controllers through pressing 1 button onboard, no copy procedure is required.

The Benefits of Using a Gear Motor

A gear motor works on the principle of conservation of angular momentum. As the smaller gear covers more RPM and the larger gear produces more torque, the ratio between the two is greater than one. Similarly, a multiple gear motor follows the principle of energy conservation, with the direction of rotation always opposite to the one that is adjacent to it. It’s easy to understand the concept behind gear motors and the various types available. Read on to learn about the different types of gears and their applications.

Electric motor

The choice of an electric motor for gear motor is largely dependent on the application. There are various motor and gearhead combinations available, and some are more efficient than others. However, it is critical to understand the application requirements and select a motor that meets these needs. In this article, we’ll examine some of the benefits of using a gear motor. The pros and cons of each type are briefly discussed. You can buy new gear motors at competitive prices, but they aren’t the most reliable or durable option for your application.
To determine which motor is best for your application, you’ll need to consider the load and speed requirements. A gear motor’s efficiency (e) can be calculated by taking the input and output values and calculating their relation. On the graph below, the input (T) and output (P) values are represented as dashed lines. The input (I) value is represented as the torque applied to the motor shaft. The output (P) is the amount of mechanical energy converted. A DC gear motor is 70% efficient at 3.75 lb-in / 2,100 rpm.
In addition to the worm gear motor, you can also choose a compact DC worm gear motor with a variable gear ratio from 7.5 to 80. It has a range of options and can be custom-made for your specific application. The 3-phase AC gear motor, on the other hand, works at a rated power of one hp and torque of 1.143.2 kg-m. The output voltage is typically 220V.
Another important factor is the output shaft orientation. There are two main orientations for gearmotors: in-line and offset. In-line output shafts are most ideal for applications with high torque and short reduction ratios. If you want to avoid backlash, choose a right angle output shaft. An offset shaft can cause the output shaft to become excessively hot. If the output shaft is angled at a certain angle, it may be too large or too small.

Gear reducer

A gear reducer is a special kind of speed reducing motor, usually used in large machinery, such as compressors. These reducers have no cooling fan and are not designed to handle heavy loads. Different purposes require different service factors. For instance, a machine that requires frequent fast accelerations and occasional load spikes needs a gear reducer with a high service factor. A gear reducer that’s designed for long production shifts should be larger than a machine that uses it for short periods of time.
A gear reducer can reduce the speed of a motor by a factor of two. The reduction ratio changes the rotation speed of the receiving member. This change in speed is often required to solve problems of inertia mismatch. The torque density of a gear reducer is measured in newton meters and will depend on the motor used. The first criterion is the configuration of the input and output shafts. A gear ratio of 2:1, for example, means that the output speed has been cut in half.
Bevel gear reducers are a good option if the input and output shafts are perpendicular. This type is very robust and is perfect for situations where the angle between two axes is small. However, bevel gear reducers are expensive and require constant maintenance. They are usually used in heavy-duty conveyors and farm equipment. The correct choice of gear reducer for gear motor is crucial for the efficiency and reliability of the mechanism. To get the best gear reducer for your application, talk to a qualified manufacturer today.
Choosing a gear reducer for a gear motor can be tricky. The wrong one can ruin an entire machine, so it’s important to know the specifics. You must know the torque and speed requirements and choose a motor with the appropriate ratio. A gear reducer should also be compatible with the motor it’s intended for. In some cases, a smaller motor with a gear reducer will work better than a larger one.

Motor shaft

Proper alignment of the motor shaft can greatly improve the performance and life span of rotating devices. The proper alignment of motors and driven instruments enhances the transfer of energy from the motor to the instrument. Incorrect alignment leads to additional noise and vibration. It may also lead to premature failure of couplings and bearings. Misalignment also results in increased shaft and coupling temperatures. Hence, proper alignment is critical to improve the efficiency of the driven instrument.
When choosing the correct type of gear train for your motor, you need to consider its energy efficiency and the torque it can handle. A helical geared motor is more efficient for high output torque applications. Depending on the required speed and torque, you can choose between an in-line and a parallel helical geared motor. Both types of gears have their advantages and disadvantages. Spur gears are widespread. They are toothed and run parallel to the motor shaft.
A planetary gear motor can also have a linear output shaft. A stepping motor should not operate at too high current to prevent demagnetization, which will lead to step loss or torque drop. Ensure that the motor and gearbox output shafts are protected from external impacts. If the motor and gearbox are not protected against bumps, they may cause thread defects. Make sure that the motor shafts and rotors are protected from external impacts.
When choosing a metal for your gear motor’s motor shaft, you should consider the cost of hot-rolled bar stock. Its outer layers are more difficult to machine. This type of material contains residual stresses and other problems that make it difficult to machine. For these applications, you should choose a high-strength steel with hard outer layers. This type of steel is cheaper, but it also has size considerations. It’s best to test each material first to determine which one suits your needs.
In addition to reducing the speed of your device, a geared motor also minimizes the torque generated by your machine. It can be used with both AC and DC power. A high-quality gear motor is vital for stirring mechanisms and conveyor belts. However, you should choose a geared motor that uses high-grade gears and provides maximum efficiency. There are many types of planetary gear motors and gears on the market, and it’s important to choose the right one.

First stage gears

The first stage gears of a gear motor are the most important components of the entire device. The motor’s power transmission is 90% efficient, but there are many factors that can affect its performance. The gear ratios used should be high enough to handle the load, but not too high that they are limiting the motor’s speed. A gear motor should also have a healthy safety factor, and the lubricant must be sufficient to overcome any of these factors.
The transmission torque of the gear changes with its speed. The transmission torque at the input side of the gear decreases, transferring a small torque to the output side. The number of teeth and the pitch circle diameters can be used to calculate the torque. The first stage gears of gear motors can be categorized as spur gears, helical gears, or worm gears. These three types of gears have different torque capacities.
The first stage helical gear is the most important part of a gear motor. Its function is to transfer rotation from one gear to the other. Its output is the gearhead. The second stage gears are connected by a carrier. They work in tandem with the first stage gear to provide the output of the gearhead. Moreover, the first stage carrier rotates in the same direction as the input pinion.
Another important component is the output torque of the gearmotor. When choosing a gearmotor, consider the starting torque, running torque, output speed, overhung and shock loads, duty cycles, and more. It is crucial to choose a gearmotor with the right ratio for the application. By choosing the proper gearmotor, you will get maximum performance with minimal operating costs and increase plant productivity. For more information on first stage gears, check out our blog.
The first stage of a gear motor is composed of a set of fixed and rotating sprockets. The first stage of these gears acts as a drive gear. Its rotational mass is a limiting factor for torque. The second stage consists of a rotating shaft. This shaft rotates in the direction of the torque axis. It is also the limiting force for the motor’s torque.
