Description: 本电路是采用Multisim7模拟的四相八拍微型步进电机的驱动电路。将步进电机的A,B,C,D4相绕组接入电路中的四个输出端，在STEPIN端输入方波信号，根据步进电机的原理可知步进电动机即可旋转。由于由STEPIN输入方波后调整运算后输出信号进行放大后驱动步进电机,所以可以得知旋转的转速与输入方波的频率成正比。
-The circuit is simulated using the four-phase 8 Multisim7 film micro-stepping motor drive circuit. The stepper motor A, B, C, D4 winding access to the four output circuits, in STEPIN ended input square wave signal, according to known principles of the stepper motor stepper motor can rotate. As the input square wave from the STEPIN adjustment operation after the output signal amplified drive stepper motor, so you can know the speed of rotation frequency of the input square wave is proportional to.

Description: 马达控制，moto的专用芯片，比用CPU要好，简洁-Introduction
The AMIS− 30512 is a micro− stepping stepper motor driver for
bipolar stepper motors. The chip is connected through I/O pins and a
SPI interface with an external microcontroller. It has an on− chip
voltage regulator, reset− output and watchdog reset, able to supply
peripheral devices. The AMIS− 30512 contains a current− translation
table and takes the next micro− step depending on the clock signal on
the “NXT” input pin and the status of the “DIR” (=direction) register
or input pin. The chip provides a so− called “speed and load angle”
output. This allows the creation of stall detection algorithms and
control loops based on load− angle to adjust torque and speed. It is
using a proprietary PWM algorithm for reliable current control.
The AMIS− 30512 is implemented in I2T100 technology, enabling
both high− voltage analog circuitry and digital functionality on the
same chip. The chip is fully compatible with Platform: |
