In response to the national call to create a green industrial manufacturing, "motor drive and control" plays an indispensable role, and its future development trend will surely move closer to the "environmental protection" theme! This is not the case, Yu Changtao, marketing manager for the motor and power control industry in the Asia Pacific region of Analog Devices, said that the future trend of motor control in the industrial sector can be summarized in four words: energy saving, efficiency, safety, and interconnection. * In terms of energy saving, the motor consumes nearly 40% of the world's energy! Energy conservation is the eternal theme. For motor control, energy saving is more reflected in the use and popularity of high-efficiency motors. * In terms of efficiency, the motor control performance is improved, thereby increasing production efficiency. * Safety is reflected in "in addition to the basic avoidance of 'machine injury', predictable health monitoring is increasingly introduced into the motor control system. * Interconnection refers to the application and popularization of real-time Ethernet in industrial sites. For the above four points, the moderator feels that it is really a point, especially the interconnection is a reflection of the current industrial Internet trend. What do you think? And ADI as a semiconductor industry, is also to provide differentiated solutions from these aspects! In the field of motor drive, the role of the motor controller can not be underestimated. How to determine whether a motor controller chip passes or not is also important. Motor control is a small system that is not implemented by a single chip. Taking the more important main controllers in the system as an example, Analog Devices introduced the ADSP-CM40x series of processors with distinctive features: high computing power; high-performance integrated SAR ADC; SINC filter implemented in hardware accelerator mode. Since I mentioned the ADSP-CM40x series, let’s talk about it. The ADSP-CM40x family of processors features industry-leading 16-bit ADCs and extensive interface resources, as well as large on-chip memory for compact layout and reduced design cycles. * Reduce total system cost with built-in 16-bit high-precision ADC and low-cost, high-performance op amps. * An additional specially designed hardware acceleration module, HAE (Harmonic Analysis Engine), is implemented on-chip to perform post-processing algorithms such as energy metering and FFT to reduce the load on the MCU. Provide customers with an easy way to implement "metering" and "protection" automation equipment. * Supports two CAN buses to enhance backplane communication, thereby increasing communication bandwidth or providing system level redundancy. * Use "differential" communication interface to enhance backplane-based system level reliability. * Integrated Ethernet MAC, supports IEEE1588. The following figure shows the ADSP-CM408F motor drive control board (EZ-KIT) and the motor drive power board. In the rise of this technological innovation industry, the fourth industrial revolution era, data-based, information-based industrial manufacturing has become a necessary trend for future development. In this era of industrial production, which type of motor will be in the future industry. "Taro" has also become a topic of people. The types of motors vary from application to application. If industrial automation is taken as an example, the application of PMSM (Permanent Magnet Synchronous Motor) is more and more extensive, the reason is simple, energy saving, high efficiency, and good control performance.
