uxcell Nema23 CNC Router Stepper Motor 100mm 4.2A 354oz.in w MB450A Driver

It is 2 phase. 1.8° Step Angle. High Step Accuracy and Resolution. Low Vibration and Noise.Can be Customized for Winding Current, Shaft Options, Cables and Connectors.Typical Applications for Nema Stepper Motor: Inject printers, Analytical and Textile Equipment, Embroidery Machine, Precision Telescope Positioning Systems, High Speed Dome Camera and Robotics, RepRap, Markerbot, CNC Router AND OTHER projects.The driver supply voltage up to +50VDC, Output current up to 4.2A.15 selectable microstep resolutions (SW4: Off=Half Current; On= Full Current), Protection against power leads(+, -)reversal.Half current function refers to no step pulse after 500 ms, the output current of drives is automatically reduced to 70% of the rated output current, to prevent electrical heating.The first three switch (SW1, SW2, SW3) of the DIP switch are used to set the current. Select a setting closest to your motor's required current. Microstep resolution is set by SW5, SW6, SW7, SW8.(0FF=0.ON=1)chopping technique, it can output more speed and power from the same motor, compared with traditional drives such as L/R drives.Enter the website for more information: http://54.235.23.96/watch_images/57HS56A4ZH.jpg
