求助英文翻译～急！

谁能帮忙把这段翻译一下，小弟不胜感激，直接用GOOGLE翻译的就不用了，根本不通。
本课题旨在电气控制实验平台上开发一套直流电机调速系统，实现电机调速功能，并给出相应的设计方案。直流电机具有良好的起制动性能，易于在较广范围内平滑调速，在许多高性能可控电力拖动系统中得到广泛应用，如轧钢机、龙门刨床、高层电梯、高精度机床等。要实现直流电机调速首先要把交流电转换为直流，这就需要整流电路。整流电路有很多种，本题目选用的是三相全控整流电路。本文详细介绍了电路的设计，元器件的选择和保护，对触发模块的分析以及硬件电路的实现。课题完成后可以直接为220V、5.3A的直流电动机供电，使其实现调速功能。

Answer 1

Who can help to translate the meantime, I would be grateful Xiaodi, the direct use of the GOOGLE will not need a translation, simply unreasonable.
Subject to the electrical control experimental platform to develop a DC motor speed regulation system, and Motor function, and gives the appropriate design. DC motor has a good effect braking performance, easy in a wider range smoothing speed, controlled in many high-performance electric drive system is widely used, such as rolling mill, the goal planer, and high-level elevator, high-precision machine tools, and so on. DC motor speed to achieve the first to convert AC DC, which requires rectification circuit. Rectifier circuit there are many, the choice of this topic is controlling the whole three-phase rectifier circuit. This paper describes the circuit design, the choice and protection of components, modules on the trigger of the circuit and hardware to achieve. Can be directly subject to the completion of 220 V, 5.3A DC motor power supply to achieve speed control function.

Who can help this section of translators, the little brother feels grateful extremely, does not use directly with Translator GOOGLE, simply does not pass.
This topic is for the purpose of the electric control testing in the platform to develop a set of direct current machine velocity modulation system, realizes the electrical machinery velocity modulation function, and gives the corresponding design proposal. The direct current machine has the good braking quality, easy in broad scope smooth velocity modulation, obtains the widespread application in many high performance controllable electric drive system, like mill, table planer, high-level elevator, high accuracy engine bed and so on. Must realize the direct current machine velocity modulation first to transform the alternating current into the cocurrent, this needs the leveling circuit. The leveling circuit has many kinds, what this topic selects is three-phase all controls the leveling circuit. This article introduced in detail electric circuit's design, primary device's choice and the protection, to trigger the module the analysis as well as hardware circuit's realization. After the topic completes, may be directly 220V, the 5.3A direct current motor power supply, causes it to realize the velocity modulation function.

Answer 3

This task aims to develop a set of timing system of direct current motor based on the experimental platform of electrical control. DC motors have well performances of both starting and braking and are easy to be timed smoothly in an extensive range, thus they are utilized widely in many controllable electrical dragging systems such as rolling mills, planers, high-level elevators, high-precision machine tools, etc. To realize the timing of DC motors, alternating current should be transformed into direct one firstly, which needs to be commutated. There are many kinds of rectifications and the three-phase full-control rectification is selected in the task. This article describes the design of the circuit, the selection and protection of the components, the analysis of the trigger modules and the realization of the hardware circuit. a DC motor (220V, 5.3A) can be electricized directly so as to realize its timing function after the task is finished.
