The latest networked motor control solution is here, share it and get a gift

For motor control solutions, ADI offers a comprehensive product portfolio, including analog-to-digital/digital-to-analog converters, amplifiers, embedded processors, iCoupler® digital isolators, power management devices, and real-time Ethernet solutions. These high-performance devices and increased system integration help to achieve newer topology designs, bringing value to customers to achieve differentiated system designs. For example, faster processors can run more complex algorithms, and high-performance ADCs can support higher-performance current loop control.

The performance of the servo drive system is closely related to the performance and accuracy of the motion control system ultimately built by the user. In most cases, the final use can be a high-precision CNC machine tool system, a networked motion control system, or a robotic system that requires precise control of position and motor torque. ADI can provide a complete solution covering all important components in the signal chain.

☑ In servo control, high-precision current and voltage sensing can improve speed and torque control performance. ADCs with at least 12-bit accuracy, multi-channel, and synchronous sampling are required. ADI offers a complete range of products.

☑ In servo systems that use resistors for current sampling, the quality of the sampled signal is critical to the current control performance. ADI provides the industry's best performance solution based on Σ-Δ modulators.

☑Position detection performance It is the key to servo control, and optical encoders and resolvers are often used as position sensors. The conversion of servo control technology from analog to digital has promoted the development of modern servo systems and also met the high requirements for motor control performance and efficiency.

☑ From the perspective of giving priority to safety and protection, isolation technology should be used for signal sampling and power device driving. ADI's iCoupler digital isolator products can meet high-voltage safety isolation requirements.

☑ The performance of IGBT power device driver protection circuits Determines the reliability and safety of the product. ADI's power device driver chips integrate a wealth of protection functions, making the design simpler and more reliable.

☑ Using high-performance processors such as DSP can achieve high-performance vector control and sensorless control.

☑Supports a variety of motion control and industrial real-time Ethernet protocols Network solutions.

☑Using an integrated power factor correction (PFC) controller , it is easier to achieve the effect of reducing the current distortion at the power input end of the servo system.

☑ In the design of industrial applications, IC products with long life cycle and high reliability are the first choice of engineers.

☑ The transformation from ordinary AC induction motors to permanent magnet synchronous motors is an inevitable trend, requiring system designers to provide higher efficiency and more flexible algorithms .

☑ High-performance real-time industrial control network better realizes the synchronization of multiple motors .

For motor control systems, industrial system design requires low power consumption and high efficiency. ADI provides single devices and complete product signal chains to speed up system design. In the signal chain, the products provided by ADI, including feedback and detection, isolation, power management, interface, embedded processing and communication, are second to none in performance and quality among similar products, and can also reduce costs at the system level. It can be said that ADI's extensive technology portfolio, including world-class isolators, processors, converters and mixed signal front ends, can meet engineers' needs for any motor control solutions now and in the future. The figure below is the system block diagram and signal chain of the ADI solution.
