Smarter, better, faster and cheaper, these words are popular slogans in today's global economy. With the development of the e-commerce industry, people are looking for simpler, more convenient and smarter automation solutions, while reducing labor costs. They are paying more and more attention to automated guided vehicles (AGV) and mobile robots (AMR) to assist in completing tasks. It is estimated that by 2022, the global AGV market will reach USD 2.65 billion.
In order to meet the demand, traction technology and the introduction of automation equipment are required. These technologies must have excellent performance, and at the same time be robust, economical, and easy to install and maintain. According to market requirements, we have specially developed a low-speed high-torque AGV dedicated motor-PMM series integrated servo motor.
The following discusses automatic guided vehicle traction solutions:
Volume requirements are critical for AGV cars, and cost control is also a consideration for every OEM.
The PMM series integrated low-voltage servo motor developed by Limaisheng has the advantages of small size, compact structure, simple wiring, low external interference, and the use of bus servo communication networking control, which greatly reduces the cost of the entire set of equipment, improves production efficiency, and can achieve private custom made.
For manufacturers who want a one-stop solution, the solution involves less design and assembly work, which is a very effective and low-cost method in the AGV system solution.
The AGV car is usually driven by one or more independent power wheels to achieve accurate walking and commutation. The rotating shaft realizes the load to rotate. (In this article, we will not consider the crawler car). The key considerations include torque and speed. Efficiency and size. All of these shafts can use PMM series complete low-voltage servo motor system and precision planetary reducer, power range 50-750W. The motor plays the role of high torque output and ensures smooth operation at low speeds during the entire car running process.
The PMM series integrated servo motor product is a bus motor, which can be connected to the EtherCAT/CANOpen communication network to realize field bus servo control. Integrated single-turn absolute encoder, zero point memory within limited range; integrated I/O, can be set to positive limit, negative limit, origin, multi-function digital output, pulse input detection. At the same time, it can customize the special functions under multiple sports modes: two-wheel differential drive mode, wheel set slip alarm, etc.
At present, PMM series integrated servo motors and drives are used in large quantities on AGV trolleys. Its superior performance also guarantees the smooth and accurate movement of the car, which has been highly recognized by the market. In the future, PMM series integrated servo motors will be more widely used in AGV and related products and industries.
