With the rapid development of AGV, there are various navigation methods and technologies, such as magnetic stripe navigation, magnetic nail navigation, visual navigation, laser navigation, fluorescent navigation, slam navigation, etc. the application of the overall AGV is also rapidly deepening and layout in the manufacturing process, accelerating the replacement of the traditional low value-added activities that rely on people to be responsible for production, logistics, and transportation. High torque AGV is more popular in the market. High quality and high torque motors are indispensable for higher torque AGV.
Advantages of AGV trolley:
1. AGV car replaces the original manual handling, greatly reducing the loss of human resources; Moreover, AGV trolley has a strong combination, high degree of automation and high level of intelligence. Moreover, because the AGV trolley is generally controlled by a computer, its driving path can be changed flexibly according to different needs.
2, advanced: AGV car integrates light, machine, electricity, and computer as a whole, and combines the advanced theory and application technology in the field of science and technology. Strong guidance ability, high positioning accuracy, and good automatic driving performance. Reduce labor and man-made operation losses; Reduce personnel, save time and shorten staffing; It can enter and exit places where people are inconvenient to enter, optimize the production structure, and save human, material, and financial resources.
3. Fast movement: AGV trolley is characterized by wheeled movement. Compared with walking, crawling or other non wheeled mobile robots, it has the advantages of fast movement, high work efficiency, simple structure, strong controllability, and good safety. Compared with the stacker, monorail trolley, conveyor belt, conveyor chain, conveyor track and national robot commonly used in material delivery, the active area of AGV does not need to lay fixed devices such as track and support frame and is not limited by site, road, and space. Therefore, in the automatic logistics system, it can fully reflect its automation and flexibility, and realize efficient, economic, and flexible unmanned production. AGV cars are widely used in factories and markets.
When the production layout changes, the corresponding adjustment is very simple. The installation and commissioning can be carried out at the production time without affecting the production. The trajectory change is flexible, and the layout can be changed at any time without affecting the production.
In July 2013, customers came to us and told us that they needed a DC motor with high torque and low speed; Their company has found several suppliers before, but they can't meet their requirements;
Brushless DC Motor Gear (motor + gearbox).
Peak torque 1100 N*m (discontinuously application).
Output speed 15 rpm
Size of the whole assembly 110mm x 110mm x 300mm max
Motor life: more than 10000 hours;
Motor noise: < 65dB
Other requirements: more than 12 small mounting holes are required for the front cover and side cover of the motor;
Note: the motor torque required by the customer is very large, and there are strict requirements for the size of the motor, and there are many installation holes required for the front end cover, so the mechanical strength of the front end cover must be considered; It can not only meet the torque but also meet the dimensional requirements.
Our entire technical team had three meetings with the customer team in the United States. Considering the use of the whole AGV car, the weight of the actual goods to be borne and the running time, and the raw materials required for the motor and reducer, we had a very detailed communication with them!
1. As for the front-end cover, in addition to the installation holes, 12 additional installation holes are added. Our design is to thicken the plate of the whole front end cover to 29mm (usually the thickness of the motor front end cover is 12mm, which is equivalent to all the internal dimensions of the whole front end cover that need to be changed);
2. Due to the use characteristics of the AGV trolley, the instantaneous use torque of the motor is very large, and the output shaft should be strong enough; We use the best hardness material for the motor output shaft, and the quenching process ensures the hardness of the motor output shaft; The winding structure and pole number inside the motor are optimized and adjusted, and verified repeatedly to ensure sufficient instantaneous torque;
3. Because AGV trolley is used in combination with battery, high efficiency is very important for motor, so it will test the service efficiency of the motor and the coordination of all parts of the rotor, stator, bearing, shell, and reducer; Therefore, strict requirements are designed for the tolerance dimensions of all parts to ensure the high standard of parts and make the efficiency of the motor reach eff1;
4. In the beginning, the customer wants to install an encoder on the motor. Through our internal design optimization, the motor is equipped with a Hall sensor. The customer can directly control the running speed of the motor through the driver and remove the encoder, which can not only achieve the use function but also save the cost.
5. The gear of the reduction gearbox adopts the gear with metal hobbing, and the lubricating oil of the reduction gearbox adopts the lubricating oil with relatively high grade, which solves the noise problem of the reduction gearbox well;
The technical team and sales team of BG motor are very responsible and professional. When they have questions, they can always answer them within 12 hours. Their team is great!
