关键词:步进电机驱动电路设计方法

摘要:步进电机的驱动电路的设计方法,部件,材料容易获得的,灵活的,光纤的复绕机,在其它系统中得到成功的应用程序。然而,因为每一步都是伴随着第二个微控制器复位,从而使电路的工作频率是不太高。

步进电机是一种将电脉冲转化为角位移的致动器。驱动器接收到一个脉冲信号,设定一个固定的旋转角度的步进电动机的驱动方向。的脉冲数,可以控制通过控制角位移量,从而达到准确定位的目的,而控制脉冲频率来控制电机转动的速度和加速度,从而达到速度的目的。

Stepper motor is an electrical pulse into the angular displacement of the actuator. The drive receives a pulse signal , the drive direction of the stepping motor to set a fixed angle of rotation . The number of pulses can be controlled by controlling the amount of angular displacement , so as to achieve the purpose of accurate positioning ; while control the pulse frequency to control the motor rotation speed and acceleration so as to achieve the purpose of speed [ 1 ] . Stepper motor has a rotor inertia end , high positioning accuracy , no cumulative error control simple. Actual operation from supply voltage, load, ambient temperature effect can be achieved fast start , braking and reversing . Stepper motor can rotate the angle and rotation speed high-precision control , stepper motor as the control actuator is a key mechatronics products, widely used in a variety of automated control systems and precision machinery and other fields. With the development of microelectronics and computer technology , increasing demand stepper motor , have applications in various fields . Stepper motor technology , after decades of the last century of development, has become a relatively mature technology . But with the promotion and application of new techniques, new technologies continue to emerge , stepper motor technology is still evolving perfected. Mainly in the improvement of the stepper motor and drive technology itself diverse and sophisticated technology and other aspects.


步进电机驱动电源同步电机本身成一个整体,其性能直接影响步进电机系统性能的优劣。

Stepper motor drive power synchronous motor itself into a whole , and its performance directly affects the merits of the stepper motor system performance .


发展的驱动电源电路:单电压驱动电路的特点是电路结构简单,成本低,绕组电路中的串联电阻,以提高电路的时间常数的电机,为了改善频率特性。缺点是:串联电阻的方法会产生大量的热量,耗电量大,驱动电源的正常运行是极为不利的,特别是当工作在高频率更严重。因此,一般用于小功率或引导,工作频率不是关键的。

Development of drive power circuit : single voltage drive circuit is characterized by a simple circuit structure and low cost , the series resistance in the winding circuit , to improve the circuit time constant of the motor in order to improve frequency characteristics. Disadvantages are: series resistance of the approach will generate a lot of heat , power consumption is large, the normal operation of the drive power supply is extremely detrimental , particularly when working at high frequencies more serious . Thus it is generally used for small power or boot , the operating frequency is not critical.

High and low voltage driver circuit is characterized by a current waveform has been greatly improved, the motor torque characteristics of a good , up and running frequency has been greatly improved . Since the winding circuit of the series resistance of several smaller , so the power consumption is small. However, due to rotation of the motor back EMF , phase mutual inductance and other factors , easy to make the end of the current waveform at high pressure and low pressure at the start of the interface is concave , resulting in decreased output torque of the motor [ 2 ] .

Chopping chopper circuit , the winding current rating of a sawtooth waveform and down fluctuations in the effective coil current corresponding to the current increases, the motor output torque increases , can be maintained subs论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
