And stepper motor drives in the engraving machine engraving machine often used drives, stepper motors in use when there are some methods: here are some that want to help our customers: 1, the current drive: is one of the important indexes of judging ability to drive current, is slightly greater than the motor drives the maximum current of nominal current, usually drive was 0. 8 a, 2, 3, 4, 5, 5。 8、6、6。 8 a, 8 a, 10 a, 13 a specification, etc. 2, drive power supply voltage: power supply voltage is the sign of judgment ability to drive up, usually drive power supply voltage: 12 VDC, 24 VDC, 40 VDC and 80 VDC, 110 vac, and other specifications. 3, subdivision drive: segmentation is a sign that the control precision, by increasing segmentation can improve the precision. Stationarity segmentation can increase motor, stepping motor usually has the characteristic of low frequency vibration, through increasing segmentation can be improved, make the motor run very smoothly.
