My Husband
My husband was a narrow-minded person and he could not bear any man’s a little affection to me. This explained that he cared about me loved me very much. But he stuck to me every minute and I did not like that. In my opinion, he should give me some personal spaces to do things I liked to do. I rode my traxxas brushless motor electric car one day, saying that I went to cut my hair; he did not believe and followed me. I really did not like his sticking to me like glue. I needed my own space to think problems. He asked me to accompany him to buy a bldc motor driver one day and I said I had no time; he got angry and rushed into the house. He thought I went to make an appointment with handsome gentlemen with my best electric bike. I explained it was not like his imagination. I could not understand why he did not trust me. I thought he looked after me too tightly and I could not breathe sometimes. He should change his methods to love me it would be better for our marriage.
Impulse Was the Devil
I had made my brother’s unhappiness several weeks ago and I had been also uncomfortable at the bottom of my heart. He had not yet spoken to me until now. I put blame on myself and was very guilty at the thought of his angry. Making him to go angry was not my ultimate purpose and I only wanted to know how he was. He promised to buy me a brushless motor fan, but he did not. I thought he was indeed busy and I did not prompt him. Two months later, I asked him whether he had taken me in his heart, he said he was still busy and asked me to buy for myself. He knew clearly that I had no money, but he should have asked me to buy on my own. I borrowed money and bought a new brushless fan motor electric car angrily. I cursed him, saying that he deceived me. I knew I had overdone. He was really busy and I should understand him. I was too impulsive. I rode the brushless motor electric car to the park to wait for him and wanted to beg for his forgiveness.
Changing Myself
I had been fed up with such kind of monotonous and painful life and wanted to end it as soon as possible. I rode an old brushless ac motor electric car to work and did very boring job every day. The work was so easy that a primary student could do it. Many people said that it was a kind of waste I worked there. I could completely find another more decent job. I believed, maybe I would resign the job and attempted to find a new one. I admired people who had new dc brushless motors electric cars riding on their way to work and I also wanted one when I had money. “Pressure is the driving force”, as the saying went. It was reasonable. I should change another job if I wanted to end this kind of monotonous life. I should not be addicted to loving a wrong person and should extricate myself from one emotion. I wanted to work in a factory, which was one of biggest brushless motor manufacturers and realized the value of my life. It was high time for me to change myself.
It Was Difficult to Live
I had a daughter and a son and both of them had gone to high school. To be frank, the burden on my shoulder had become heavier and heavier with the passing of time. I worked in a nursing house and my income was not so promising. I rode a cheap brushless dc motor electric car to the nursing house every day. Because of the pressures of life, I wore a troubled look everyday and could not cheer up myself in any way. I often thought why I was so unlucky. We lived a thrift and hard life, and more unfortunately, I was down with heart disease. My electric car was too old to repair and I wanted Velineon 3500 brushless motor electric car, but I could not afford, so I had to take a bus to work afterwards. I pulled a long face when I was waiting for the bus and there was a young girl sitting beside me at the station. She told me that I should extricate myself from hatred and anxiety. She said she worked in Himax brushless motors factory and I could call her if I encountered difficulties.
My Regret
I had a bad mood recently, because I had said some hurtful words to my favorite person and caused his unhappiness. It was all my faults and I should not have said that kind of words to hurt him. I wanted to make an apology for him, but he did not answer my telephones, nor replied my short messages. He treated me very well and bought me an ac brushless motor electric car, clothes and shoes when I was lack of money at the beginning of arriving here. He had done everything humanly possible to me and I should have been content. But I could not bear when he said that I was greedy and vexatious. I could not settle down myself and was fed up with the noisy sounds of the brushless dc motors outside. I said many harsh words to him and I knew that he had gotten angry. When he did not answer my phones, I knew that I had made unforgivable mistakes. I rode my micro brushless motor electric car to his house; his store and his office, but I could not find him in any way. I regretted very much and hated myself.
Loving a Wrong Person
I felt extremely tired and I thought I should put down the sentiment, for I was very painful and riddled. There was nothing wrong with loving a person, but I had fallen in love with a wrong person and loved him in a wrong time. He was twelve years older than me. I hated why my mother had not born me thirty five years ago. He was an ordinary worker in an electric brushless motors factory for nineteen years and had a complete family. His wife loved him very much, but he did not love her so much. Although he did not love her very much, he could not abandon her, after all, he was a responsible man and he had to live with her in his whole lifetime. I rode my brushless dc motor electric car to his office one Sunday. He said that he knew I loved him very much and he also loved me, but he could not divorce his wife. He persuaded me not to be obsessed with him that much. I left there on my small brushless motor electric car sadly. Indeed, it was unrealistic to for me to marry him.
Staying or Leaving
I did not know whether I should stay or leave after he did not speak to for the whole week. My heart was broken when did not talk with me. He was my only friend in this city and I did not want to lose him. He recommended me to work in an electric brushless motors factory when I arrived here. He had helped me for many times and I was moved to tears when he stretched his helping hands without hesitation. I thought I had encountered the kind person. I was indeed lucky. I would have left here very long ago if I had not encountered him. I rode my brushless motor electric car to the factory every day and passed by his snack bar every day. I enjoyed my happy life of meeting him. But there were many unhappy things between us afterwards and he did not speak to me anymore. I resigned the job in brushless dc motors factory and wanted to leave here. I could not live without him and my life would be boring without his accompany.
Being Restless at Weekends
I could not concentrate my attention on anything since I knew him. I had been completely attracted by his kindness and his knowledgeable. I thought of him when I was riding my dc brushless servo motor electric car on my way to work; I thought of him when I was working; I thought of him when I was eating; I thought of him when I was sleeping. I could not settle down at Sundays, because I wanted to meet him, but he had no time to accompany me. I was not convinced. He asked me to ride the brushless dc motor electric car to the public park in the city center; I did not want to go there. He asked me to look for a part-time job as a tutor at the door of Xinhua bookstore; I did not want to go. I only wanted to make an appointment with him and had a pleasant talk with him, but he could not meet my requirements. The noise of electric brushless motors outside made me more restless. I was disappointed to death. I lied on my bed and my tears poured down. I could not bear his busying.
Being Pressed by My Father-in-law
After I got married with my husband, we were both busy with our careers. My husband had an orchard and had to take care of it every day, and the garden needed his management. I worked in an outrunner brushless motors factory and there were many things waiting for me to do every day. When our careers were on the right tracks and flourished day by day, my father-in-law prompted us to give birth to a baby every day, saying that careers were of course very important, but we could not delay giving birth to a baby. He even took the matter to give me pressure and became fed up with me one year later. I was sad and rode my brushless dc motor electric car to my husband’s garden after my father-in-law cursed me being unable to be pregnant. I saw him was busy, so I went back. I went to the river bank on my micro brushless motor electric car and did not know what I should do. I knew they were anxious to have a grandchild, but we only wanted to make more money at that time.
SAMSR MOTOR is plan to expand Chinese makket
Is well known that the brand and type of electrical products has been dazzling in the market, SAMSR MOTOR Select stationed at this time must in the face of quite large competition, but it has its own unique ideas on the development of new products, as to the development of new stepper motor this time, the company in the ability to occupy the market is clearly in the answers, mainly due to the current stepper motor exist very serious price war.
It is understood that SAMSR MOTOR is going to launch permanent magnet stepper motor market silicon and original Japanese NSK brushless motor, compared with other brand stepper motor, they with accurate positioning, high output torque and high response frequency. All along, various motor products of SAMSR MOTOR are the first choice for customers around the world.
Use inverter fed into induction motor
Using inverter can achieved the required voltage and current’s regulation of AC motor. The limitations of the past are the need of using direct start, star delta starter, soft starter and similar technology, but these techniques have been eliminated by the inverter. The main section contains three-phase voltage source inverter (VSI) of the six IGBT / diode and gate drive. Currently, the Intelligent Power Module (IPM) has become an increasingly popular alternative solution. Now the drive can achieve four-quadrant operation. Use of the accurate control signal can adjust the motor’s current and speed. Rotating direction and the direction of energy transmission is optional. Induction motor is easy and convenient to use, so it replaces ac motor and have been widely used in a verity of fields.
Three-phase voltage source inverter
Field oriented control (FOC) technology is popular in the three-phase AC motor，which to achieve fast dynamic response. The technical solution imitate the work of DC motor, the working principle is based on the complete decoupling of two current components: squirrel-cage motor torque generated in the magnetic flux generating current component and the current component. This contains the required external components. Using Clarke and Park transformation can convert the three time-varying output current (ia, ib, ic) into 2 time-invariant values (Id, Iq). Thus, the final DC value will be controlled easily. The difference between the measured value of Current component and the expected value depends on the speed induction motor required.
Sensor less control technology of AC motor is still a subject of concern and a growing area of research. In the case of use of IM, sensor less control can be simplified, because the squirrel-cage motor location is not necessary for the motor work. If you need speed control, the rotor position can be calculated directly through the so-called back-EMF (BEMF).
The main obstacle to the development servo motor
Current international high-precision servo device sensor has been raised to 200 million lines to 400 million lines, and then it is able to match the existing mechanisms to achieve nanometer-level control. Our domestic control can guarantee that the domestic high-speed synchronous sampling digital communication protocol we adopted is necessary to solve the problem. Servo motor own High-precision control problems must be solved. FANUC emphasizes HRV (High Response Vector control), Mitsubishi stressed OMR (optimal mechanical response of control) are directed at high-precision servo control problem of the core issues - high precision, fast response of the current loop design. Only good current loop characteristics can provide perfect performance for the good speed control and position control.
many control techniques can make a difference in resolving this contradiction, including state recognition, control, and variable parameter control synovium and so on. To realize High precision control, only rely on the controller and servo drive is not enough. Motor design itself is an important factor in the effect of motion control. For permanent magnet synchronous servo electrical motor, a good positive spin of EMF, cogging force very little low-speed servo drives will be benefit to achieve smooth control.
