     步進電機具有明顯的優勢超過其他電動機,這些優勢與精密控制有關,以及其相對較低的成本,步進電機有許多高科技技術應用在程序上,如機器人和遙控車等等。
什麼是步進電機
     步進電機是在電機中一個要對較新的現象,只是最早的電機只是用電線線圈,磁鐵的存在,隨即與電流。步進電機推出精確的速度和通過使用微處理器控制電機的位置。由于電機的移動位置步驟位置,電機成為被稱為“步進電機”。
步進電機的應用
     步進電機的允許電機同步,這可能不是什麼大不了的,似乎直到你意識到有許多這樣的電機應用。步進電機控制器的同步,使工廠能夠精確地控制電機所產生的流量或輸出,使機器人移動精確,並允許控制和定位的東西如相機。它也是用于轉速控制。使用步進電機的另一種方法是在遠程控制的應用。
為什麼要使用步進電機?
     如直流無刷電機,其他電機不提供罰款的步進電機控制。但是,他們也有對步進電機的一個優勢是其成本較低。其他電機也有不要求其控制的微處理器,增加的復雜性,可以建立企業和愛好者的停機時間和費用的額外的好處。
成本和效率
    即使步進電機因為所涉及的許多磁崗位,從而招致更大的成本為用戶使用更多的電力,磁鐵高未必是一件壞事,因為他們還創造一個更強大的高轉矩電機,在低角速度。這使得許多愛好者的應用非常有用的電機,特別是對自動化系統和機器人的建設者。機器人的制造商傾向于這種類型的電機,因為它允許對的位置和移動速度的精確控制,並且很容易由一個微處理器控制的

Stepper motors have distinct advantages over other motors. These advantages are linked to precision control factors as well as their relatively low cost. Stepper motors have many applications in both high technology and in hobbies such as robotics and remote cars.
 
What Are Stepper Motors?
Stepper motors are a relatively new phenomena in the world of motors. The earliest motors were merely coils of wire with an electric current that spun in the presence of a magnet. Stepper motors introduced precise speed and control of the motor position through the use of microprocessors. Since the motor moves from location to location in steps, the motor became known as the "stepper motor."
 
Applications
The stepper motor allows synchronization of a motor, which may not seem like a big deal until you realize that there are numerous applications for such a motor. The synchronization of a stepper motor controller allows factories to precisely control the flow or output produced by a motor, allows robots to move with precision, and allows control and positioning of things like cameras. It also is used for rotational speed control. Another way to use stepper motors is in remote-controlled applications.
 
Why Use a Stepper Motor?
Other motors, such as the brushless DC motor, do not offer the fine control of the stepper motor. But one advantage that they do have over stepper motors is their lower cost. Other motors also have the added advantage of not requiring a microprocessor for their control, as the added complexity can create downtime and expense for businesses and hobbyists.
 
Cost and Efficacy
Even though stepper motors use more electricity because of the numerous magnetic positions involved, and thus incur a greater cost for the user, the high number of magnets isn't necessarily a bad thing because they also create a more powerful, high torque motor at low angular velocities. This makes the motor useful for many hobbyist applications, especially for builders of automated systems and robots. Builders of robots tend to favor this type of motor because it allows precise control over the position and speed of movement, and is easily controlled by a microprocessor (see Resources below).
