Overview

UIM24002/24004/24008 is a series of miniature, high performance stepper motor controller. They can be mounted onto 42/57/86/110 series stepper motor seamless through corresponding flanges. The thickness of these controllers 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.

Overview

UIM24204/24208 are miniature, intelligent stepper motor controllers equipped with CAN (control area network) bus for building up local motor network. By using these motor controllers, user can control multiple motors in real-time. To communicate with these motor controllers, user needs one CAN-RS232 converter (UIM250, sold separately). The UIM250 CAN-RS232 converter communicates with the user devices/controllers through RS232 protocol using ASCII codes. Through this fashion, users can operate these controllers with minor or no knowledge about the stepper motor driving and CAN bus. The structure of the instructions (i.e. commands from user) is simple, straightforward and fault-tolerating. UIM24204/24208 can be mounted onto 42/57/86/110 series stepper motors seamlessly through corresponding flanges. The thickness of these controllers is less than 14 millimeter. Enclosures of UIM24204/24208 are made of die-cast aluminum which provide a rugged and durable protection to the controller and improve the heat dissipation..

UIM24302 Micro stepper motor controller

Feature:
Micro Size, 16mm*24mm*2.5mm
Embedded stepping pulse generator, adjustable frequency
ON/OFF, Reset, Direction 3-wire control
10-35V DC, 2A adjustable phase current, 16 microstepping
TTL Logic control

Overview:

UIM24302 is a high performance stepper motor controller that features micro miniature size and 2A max phase current. The size is only 16mm*24mm*2.5mm. Onboard 555 timer based stepping pulse generator unit eliminates the need for external pulse source. The pulse frequency is adjusted through an onboard potentiometer. Once the frequency is set, user only needs 2 signals to control the motor: on/off, direction. The Reset signal input can put the controller into sleep to maximum the power saving. If not needed, leave it open.
We also offer quick engineering design service to satisfy the needs of single power supply, different microstepping options, photocoupler isolation and embedded control system, etc.
