My ex-husband sent me the divorce agreement several days later; I signed my name on the agreement and I was single from then on. I had no job and no husband within several months. Things had changed so rapidly and I felt very sad. The first time I thought of was to go to the bar and drink beer to drown all my sorrows. I went on my motorized bicycle and went the nearest bar. I drank one bottle of beer after another and after a long time, I heard a voice saying that they were going to close the door I paid for the beer and went out of the bar. I had been drunk, but I could still remember my mamba brushless motor electric car and wanted to ride it home. I felt a little dizzy and could not see things very clearly in front of me. The guard saw me being unable to stand steadily and asked me to take a taxi home instead of riding the electric power bike and he would help me looking after the electric car. I followed his advises and stood by the roadside waiting for a taxi.

What are electric bikes? E-bikes, as they’re called, are not scooters. They don’t travel at those speeds (most going at a max of 20 mph), and they have pedals just as regular bicycles do, which riders can use to travel at their own steam. When the terrain gets rough, cyclists either turn a key or push a button to engage the motor. E-bike doesn’t replace their effort, but it does allow them to cycle farther and faster with less exertion. These vehicles do not run on fossil fuels, so they’re a relatively “green” mode of transportation; a removable battery is the power source. “There’s no learning curve to using these bikes,” assures Dan Lehman, owner of the e bike tour company Austin Lehman, the first North American outfit to use these bikes widely on its tours. They’re very intuitive, with brakes that are the same as on a normal bike.

Back to the 30s century, people have began to develop brushless DC motor to replace the mechanical brush commutation. After decades of effort, until the early 60s of last century this dream finally comes true, Since the 70s of last century, with the rapid development of power electronics industry, many high-performance power semiconductor devices, such as GTR, MOSFET, IGBT, IPM appeared in succession, and the advent of high-performance permanent magnet, brushless DC motors’ widely used is in laying a solid foundation.
Brushless DC permanent magnet motor main body composes of the motor, motor controller and electronic switching circuit three parts. The stator windings general made of multi-phase (three-phase, four-phase, five-phase range).

Servo motor belongs to control motor; it is divided into a DC servo motor and AC servo motor two types. Due to AC servo motor with a small, light weight, high torque output, low inertia and good control performance feathers, thus it has been widely used in automatic control systems and automatic detection system as the implementation components and the control signal is converted to mechanical shaft rotation. the servo motor’s positioning accuracy is very high, the modern position control system has been increasingly used to servo motor as the main components of the position control system. The design here is closed by controlling the relay, disconnect, and to control the pulse width of the size of the objective of non-standard through the closed loop AC servo motor controlled sliding displacement of the magnetic block, using magnetic field to reach the motor controls speed purposes.

Echo was born in a rich family. She was the school flower of our university and every student discussed her every day. She turned a blind eye on any other outstanding boy’s pursuit and fell in love with a poor boy on the contrary. No one of us could understand why she should have had fallen in love him. She would ride her gas powered bicycle or take a taxi to school before she fell in love with him, but she went by the bus when she decided to ran after him, because she wanted to take the opportunity to meet him in a short distance. He rode his electric trike to avoid her, because he thought that he did not match her and he did not want to become other students’ jokes. But she still insisted to pursue him. He told her one day that he did not want her like that and that she could find a better man than him. She went on her homemade brushless motor electric car and ran after him with the quickest speed. She told me that she would never give up pursuing him before he promised her.

I was transferred to work in our local government after one year of working in the health center. I was very happy when I heard the good news and there was no exception to my parents, who were extremely proud of me. The happiest person was my girlfriend, who jumped when I told her the news. He bought me a new electric e bike before I went to work in the government. My parents held a celebration for me and there were many people coming to the party to congratulate me. I was the first university student in our village and they were happy for me. My parents worked in an electric brushless motors factory and their workshop director also came to the celebration. I did not know how to express my feeling that day. I was happy on the one hand, and felt a heavy stress at the bottom of my heart on the other hand. I went to the government ten days later when another people arrived at the center and replaced me. She rode a motorized bicycle wearing a sweet smile that day. I thought she could do the job well.

I was pleasant to spend my Sundays on staying with him, even though he was unpleasant to speak to me or meet me or really had no time. It was my pleasure to spend time on him, as long as I could meet him. It rained heavily one Sunday, in order to have a look at him; I rode my small brushless motor electric car to find him everywhere. He was not in his snack bar, so I went to his office. He was indeed down there. He was playing cards. I sent him s short message, saying that I was at the door of his office and wanting him to come out. I waited for him for the whole day, but he did not reply my short message, nor came out. I left there on the 12 volt dc motor electric car when it was dark. Since he did not want to meet me, nor spoke to me, I would not force him and disturb him, so long as he did not go angry with me anymore and I would be very content. I swore that I would no longer press him to meet him. I went to the electric bikes shop the next day as usual, because life had to continue.

I wanted to frighten my colleague’s husband when he did not trust me and suspected that I had ambiguous mind towards her wife. I scared him that I was on the way to her wife’s house on my brushed dc motor electric car when I called him one night. I told him that I was innocent and had never had any evil intention on her wife. But he did not believe; I repeated, he still did not believe, so I got angry and decided to scare him. He worked in another place. When I said I was on the way to their house and let him heard the noise of the dc brushless motor, he was really nervous and hurry. He begged me not to go and not to do stupid thing; I did not listen to her words at all and continued going on. The steel door was close when I arrived at their house. I tried to go in through the gap and my head was pressed; I could not neither enter nor come out. A person riding an electric e bike came several minutes later. it was my colleague’s father, who just got off work and saved me in the end.

I heard one of my colleagues cursed me, saying that I was a scoundrel and many other harsh words that injured me deeply when I was at the door of our company one day. I had not done anything wrong and why she cursed me like that. I could not understand. I stopped my sensored brushless motor electric car and entered the company. I asked her why she abused me. Her face became red and she was speechless suddenly. She told me that she only cracked a joke with her husband in the telephone and had no hostility on me. I did not believe what she said. I rode my electric e bike and went to ask his husband. Her husband told me that he did not trust me and was afraid that I had affection towards his wife. He did not trust me and asked her wife to curse and so that he would believe there was nothing between us. I left his electric hub motors factory angrily. I had never had anything thought on his wife and more importantly I had my own girlfriend. I thought he had thought too much.
