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.
cpu 奔4 3.0主板 GA8I915PL-G硬盘 日立500G SATA (今天新买的)分区之后做系统报:#88错误,找不到指定磁盘查找解决方法如下:1。要排除BIOS设置问题(或者主板电池有没有电)。2。要排除硬盘跳线设置错误的问题。在冒昧的问下,我的板子是不是不支持SATAII的硬盘,还是电源供电不足的问题?
