Stepping drive Overview

UIM24002/24004/24008 stepping drive are a series of miniature, high performance stepper motor controller.  They can be mounted onto NEMA17, 23, 34 and 42 stepper motors seamless through corresponding flanges.  The thickness of these stepper motor driver is less than 14mm, UIM 24002 is capable to provide 0.5-2A adjustable current. UIM 24004 is capable for 1.6-4A adjustable current output. UIM24008 is capable for 2A-8A.adjustable current output.  Their mixed-decay current control reduces the back-EMF effect under high speed  running condition and improves the performance. Except the UIM24002 takes 10-35VDC input, UIM240xx series stepper motor driver can work with 12 to 40VDC input.. Enclosures of the UIM240xx stepper driver are made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation..
