This is quite different from the past the motor with motor control theory, control theory, fast progress and modern digital PWM control technology, so that the permanent magnet brushless motor has been the rapid development of the permanent magnet brushless DC motor has been widely exist in daily life, and has been widely used.The focus of this design is the design of hardware and software design of the motor. The control system for brushless DC motor, the most important part is the driving motor, followed by determination of motor running direction by position sensor; the position sensor in place of the brush plays an important role for the signal chip an important component of signal acquisition for processing over the feedback control through the microcontroller programming, so that the normal operation of Brushless DC motor.Keywords:：Permanent，Position sensor-less，Control，Singlechip PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 1目 录TOC \o 1-3 \h \u HYPERLINK \l _Toc30418 1 绪论 PAGEREF _Toc30418 1 HYPERLINK \l _Toc7625 1.1 永磁无刷直流电机的发展历史 PAGEREF _Toc76
