This session will talk about the different types of motors used in the industry; DC, Brushless DC, Steppers, Permanent Magnet Synchronous, and AC Induction. To gather a better understanding of motors, differences of these motors with advantages and disadvantages of each will be shown. Basic motor drive circuits will be discussed from full H-Bridge drive to half-bridge for 3-phase motors. Other drive concepts such as 6-step commutation along with drive issues such as current recirculation will be discussed. Field Oriented Control will also be discussed and how it has progressed with improving technology. This session will end with how to implement a motor control application using TI solutions from analog products, digital controllers and software to precisely control the position, velocity and torque of mechanical drives.
下午看了看Microchip家ATSAMD51P20A的官方介绍,不知道是不是打开的方式不对,发现没有中文界面了,都不能选择国家语言了最近都在盯国产MCU,原来常见的atmel家mcu感觉已经陌生啦,哈哈,看了看说明,感觉描述不同的地方:up to 1 MB Dual Panel Flash with ECC, and up to 256 KB of SRAM with ECCFLash和SRAM
