My house leaks water
May 30 2011, 4:15 AM
Likes the usual, I reach the home in time when the pins of my omega watch point the six o’clock. I decide to have a show about my cooking because my roommates all aren’t at home. The kitchen owns me whole. I like the feeling. To tell the truth, I am a girl who likes cooking very much. As long as I have free time, I will spend a lot of time on the kitchen.
So before up the stairs, I go to vegetable market and buy a fish and a few vegetables. And ready invites Ally to share the lunch with me together. Ally is my partner. She helps me lots of, special this Gucci watches case.
But to my big surprised, I find there has not any water when I open the water faucet. On that moment, a police with a franck muller replica watch knocks my door. He is doubt my house leaks water and he is surveying. Before the result of the survey, he will stop the whole water in my house. I can’t do anything besides noticing to Ally the party is deleted.

Being Anxious to See a Person
May 16 2011, 2:50 AM
I would spend my life in repentance if he did not forgive me. I would cry every time at the thought of his angry face. I was very happy because of his existence at the beginning of knowing him, but I gradually could not leave him afterwards and became very painful when I could not meet him for at most a week. I rode my Velineon 3500 brushless motor and went to the river bank near my house. It was the place we often made appointments before. I called him and said that I was waiting for him there with my brushless dc electric motor electric car and I would not leave before he came there. He was unpleasant and got angry, saying that I was unreasonable and I throat him. He did not like to be threatened by anybody. He did not come and I left there on my brushless dc motor electric car disappointedly. I had never thought he should not come. He sent me a message saying that he would not meet me from that time on. my tears poured down at the seeing of the short message.

Two kinds of common servo motor and control system
May 12 2011, 8:51 PM
The development of the modern motor control theory made CNC machine servo system realize communication, digitalization and intelligent. Among digital, intelligent CNC system, Open-loop control system, Half-loop and closed loop position control system are the common servo motor and control system.
Open-loop control system uses a stepper motor as driven device. the main difference between Stepper motor and ordinary motor is the impulse control, because of this characteristic, stepper motor can combined with modern digital control technology. However, the control precision, speed range, low-speed performance of stepper motor is worse than s traditional closed-loop controlled dc servo motor.
Semi-closed-loop and closed loop position control system adopt DC servo motor or AC servo motor as the drive components, to form high-precision closed loop position control system.

Basic structure of dc motor
May 11 2011, 12:56 AM
DC Motor adopts octagonal full-laminated structure, it not only highly utilize the space, but also can withstand the pulsating current and fast load current changes when use the static power converter. Generally, DC motors without series excitation windings; they are suitable for the automatic control technology that needs to turn by positive and negative electric motor, They Can also be made to winding according to user needs. The motor with Center height from 100 ~
Among all motor, the most widely used category is AC induction motor (also known as the induction motor) and dc brush motor, they are easy to operate.
