步进电机的控制 摘 要 步进电机（Stepping Motors）是一种将输入的电脉冲信号变换为阶跃性角位移或直线位移的电机,既给一个脉冲信号,电机就转动一个角度或前进一步,故而又称为脉冲电机。它输出的角位移与输入的脉冲数成正比,转速与脉冲频率成正比。步近电机必须与驱动器、控制器配套使用才能完成工作要求。 本设计采用89C52 16位单片机对步进电机进行控制，通过IO口输出的具有时序的方波作为步进电机的控制信号，信号经过芯片UIN2003和74LS14芯片构成驱动电路驱动步进电机；同时，用 4X4的键盘来对电机的状态进行控制，并用数码管显示电机的转速，采用74LS164作为4位单个数码管的显示驱动，从单片机输入信号；利用ISD2560语音芯片的语音功能播报电机的转速。 关键词： 步进电机 单片机 数码管 Abstract Tread into the electrical engineering(The Stepping Motors) is a kind of electricity pulse signal transformation that will input to jumps sex Cape move or the straight line to move for the rank of electrical engineering, since give a pulse signal, the electrical engineering turns to move an angle or fronts further, hence be called the pulse electrical engineering again.Its outputs Cape move with the importation of pulse the number becomes the direct proportion, turning to become the direct proportion with the pulse frequency soon.Tread the near electrical engineering must then can complete the work request with actuator, the controller kit usage. The This design adopts 16 machine the SPCE061As of the the the sun to the carry on the the control the towards treading the into the the electrical engineering, the pass an the outputs has the the cycle the time of the a conduct the and actions the tread into the the control the signal of the the electrical engineering, the the signal the drive to the tread into the the electrical the engineering through the the chip L298N; At the same time, use the keyboard of the 4 X4s to the electrical engineering of appearance carry on the control, counteract the figures tube manifestation electrical engineering to turn soon, adopt the 74 LS164s to be 4 single pieces code tube of manifestation drive, from a machine importation signal; The speech function that makes use of a machine of sun of reports the electrical engineering to turn soon.
