     步进电机具有明显的优势超过其他电动机,这些优势与精密控制有关,以及其相对较低的成本,步进电机有许多高科技技术应用在程序上,如机器人和遥控车等等。
什么是步进电机
     步进电机是在电机中一个要对较新的现象,只是最早的电机只是用电线线圈,磁铁的存在,随即与电流。步进电机推出精确的速度和通过使用微处理器控制电机的位置。由于电机的移动位置步骤位置,电机成为被称为“步进电机”。
步进电机的应用
     步进电机的允许电机同步,这可能不是什么大不了的,似乎直到你意识到有许多这样的电机应用。步进电机控制器的同步,使工厂能够精确地控制电机所产生的流量或输出,使机器人移动精确,并允许控制和定位的东西如相机。它也是用于转速控制。使用步进电机的另一种方法是在远程控制的应用。
为什么要使用步进电机?
     如直流无刷电机,其他电机不提供罚款的步进电机控制。但是,他们也有对步进电机的一个优势是其成本较低。其他电机也有不要求其控制的微处理器,增加的复杂性,可以建立企业和爱好者的停机时间和费用的额外的好处。
成本和效率
    即使步进电机因为所涉及的许多磁岗位,从而招致更大的成本为用户使用更多的电力,磁铁高未必是一件坏事,因为他们还创造一个更强大的高转矩电机,在低角速度。这使得许多爱好者的应用非常有用的电机,特别是对自动化系统和机器人的建设者。机器人的制造商倾向于这种类型的电机,因为它允许对的位置和移动速度的精确控制,并且很容易由一个微处理器控制的

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).
