Smarter, better, faster, and cheaper, these words are the buzzwords of today's global economy. With the development of the e-commerce industry, people seek simpler, more convenient and intelligent automation solutions, while reducing labor costs, and pay more and more attention to automatic guided vehicles (AGV) and mobile robots (AMR) to assist in completing their work. It is estimated that by 2022, the global AGV market alone will reach 2.65 billion US dollars.
In order to meet the demand, traction technology and the introduction of automation equipment are required. These technologies must have excellent performance, while being robust, economical, and easy to install and maintain. According to market requirements, we have specially developed a low-speed, high-torque and braked AGV motor-PMM series integrated servo motor.
The following discusses automated guided vehicle traction solutions:
The volume requirement is very important for AGV trolleys, and cost control is also a consideration for every OEM.
The PMM series integrated low-voltage servo motors developed by NIMOTION are small in size, compact in structure, simple in wiring, and low in external interference. The use of bus servo communication networking control greatly reduces the cost of the entire set of equipment, improves production efficiency, and can be customized.
For manufacturers who want a one-stop solution, the solution involves less design and assembly work, and is a very effective and low-cost method in AGV system solutions.
AGV trolleys are usually driven by one or more independent power wheel drive shafts to achieve precise walking and commutation. The rotating shaft realizes the rotation of the load (we will not consider the crawler trolley in this article). The key considerations include torque, speed, Efficiency and size. These axes can use the complete set of low-voltage servo motor system and precision planetary reducer of the PMM series, and the power range is 50-750W. During the entire operation of the trolley, the motor has a large torque output and at the same time ensures smooth operation at low speeds.
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 memory within a 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, you can customize the special functions in a variety of sports modes: two-wheel differential drive mode, wheel set slip alarm, etc.
At present, PMM series integrated servo motors and drives have been widely used in AGV trolleys. Its own superior performance also ensures the smooth and accurate movement of the trolley, which has been highly recognized by the market. In the future, the PMM series integrated servo motors will be more widely used in AGVs and related products and industries.
