请翻译一下下面的句子：
本设计以AT89C2051单片机为核心，通过三个按键来达到控制直流电机的启停、速度和方向，完成了基本要求和发挥部分的要求。在设计中，采用了PWM技术对电机进行控制，通过对占空比的计算达到精确调速的目的。

This design take at89C2051 monolithic integrated circuit as a core, achieves the control direct current machine through three pressed keys to open stops, the speed and the direction, has completed the essential requirements and the display part request. In the design, used the PWM technology to carry on the control to the electrical machinery, through the computation achieved the precise velocity modulation to the dutyfactor the goal.

里面有些语法修改下就好了

The design AT89C2051 SCM as the core, through the three keys to achieve the start and stop motor control, speed and direction, completed the basic requirements and play a part of the request. In the design, using the PWM technology to motor control, through the calculation of the duty cycle to achieve precise speed control purposes.
