说明：  利用DSP控制直流无刷电机 直流无刷电机实际属于永磁同步电机，一般转子为永磁 材料，随定子磁场同步转动。这种电机结构简单，而且由于 移去了物理电刷，使得电磁性能可靠，维护简单，从而被广 泛应用于办公自动化、家电等领域。
(use DSP Brushless DC motor control brushless DC motor is actually permanent magnet synchronous motor, general of the permanent magnet rotor material, with the stator magnetic field out of sync. Such Motor simple structure, but due to the removal of physical brush, making electromagnetic reliable performance and easy maintenance. which is widely used in office automation and home appliances, and other fields.)
