Servo Motors Seek to Break Through

China's robotics industry is in an era of great transformation, and it needs rapid innovation and integration. As a high-tech, robotics is an important support method to promote the development of the industry. In order to vigorously develop the robot industry, servo motors, which are one of the core components of robots, have naturally become popular areas for publicly competing layouts.

On the road to the rise of Chinese domestic robots, the localization of core components is a very important content. The data shows that due to the lack of serious core components in China's industrial robot companies, they are mainly concentrated in the ontology and integration. From a cost perspective, core components account for about 72% of the cost of industrial robots. It is understood that China's industrial robot servo system will reach a market scale of 4.7 billion yuan by 2020, and the compound annual growth rate will be about 35% in the next five years.

The servo motor is a kind of auxiliary motor indirect transmission device, which can control the speed and accuracy very accurately. The voltage signal can be used as the torque and speed to drive the control object, which is equivalent to the "nervous system" of industrial robots. In the domestic servo motor market, the top three brands, Panasonic, Mitsubishi, and Yaskawa, are Japanese brands, with a total share of 45%. European brands such as Siemens, Bosch, and Schneider occupy high-end, overall market share is around 30%, and the overall share of domestic companies is low. At 10%. Japanese brands monopolize the small and medium-sized OEM (equipment manufacturing) market with good product performance and competitive prices, and foreign companies in the servo system have an absolute advantage.

At present, efficiency has always been a top priority for servo systems. It mainly includes the high efficiency of the motor itself: for example, the improvement of the function of the permanent magnet material and the very good structure planning of the magnet equipment; also includes the high efficiency of the drive system: including the optimization of the inverter drive circuit, the optimization of acceleration and deceleration motion, and reproduction Dynamic and energy reverberations and very good cooling methods.

Unlike conventional motor tests, servo motors perform primarily in control speed and control accuracy. This raises the question that traditional motor test methods are only for motors and cannot analyze the control characteristics of servo systems. .

For this situation, the MPT hybrid motor inspection system can load the tested motor continuously and dynamically through the loaded engine technology, and simulate the working condition of the tested motor in the real environment. Then the corresponding motor and control can be turned on. Dynamic echo control, practical condition simulation, and aging tests have enabled motor testing to enter a dynamic era and meet the needs of the servo motion system industry for motion control related projects.
