Overview
UIM 24008 is a miniature, high performance stepper motor driver. It can be mounted onto 86/110mmNema34 and Nema42 stepper motorseamless through corresponding flanges. The thickness of these driver is less than 14mm, UIM24008 is capable for 3A-8A. adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high speed running condition and improves the performance. Enclosures of the UIM24008 stepper motor driver is made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation.
