該步進(jìn)電機(jī)驅(qū)動(dòng)器又稱為EasyDriver,EasyDriver能夠?yàn)閮杉?jí)步進(jìn)電機(jī)提供大約每相750mA(兩極一共1.5A)的驅(qū)動(dòng)。它默認(rèn)設(shè)置為8步細(xì)分模式(所以如果你的電機(jī)是每圈200步,你使用EasyDriver時(shí)默認(rèn)為每圈1600步),更多細(xì)分模式可以通過將MS1或MS2兩個(gè)接腳接地進(jìn)行設(shè)置。這是一種基于Allegro A3967驅(qū)動(dòng)芯片的細(xì)分斷路器。對(duì)于此設(shè)計(jì)的完整規(guī)格,請(qǐng)查閱A3967的參數(shù)表。它的最大每相電流從150mA到750mA??梢圆捎玫淖畲篁?qū)動(dòng)電壓大概是30V,其中包括板載5V的調(diào)壓器,所以只需要一個(gè)電源。質(zhì)優(yōu)價(jià)廉,這玩意兒只要十幾美元,比你自己制作電路板更便宜。
步進(jìn)電機(jī)驅(qū)動(dòng)器設(shè)計(jì)特色:
- A3967 Microstepping Driver
- MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
- Compatible with 4, 6, and 8 wire stepper motors of any voltage
- Adjustable current control from 150mA/phase to 700mA/phase
- Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
