Q2Hb34Ma 2-Phase Stepper Motor Driver

Constant angle, constant torque micro step driver, the drive voltage of which is from 12V to 40VDC. It is designed for use with 2 phase hybrid stepper motor of all kinds with 42mm to 57mm outside diameter, 6, 8 leads, regulated phase current from 0.5A to 3A. The unique control circuit that it adopts can reduce motor¡¯s noise, make motor run more smoothly, improve motor's performance by 30% at high speed, reduce driver¡¯s heating by 50%. It is widely used in small size of numerical control devices with higher resolution such as carving machine, laser labeling machine, inner laser curving machine and etc. FEATURES * 4 channels constant angle and constant torque micro step, highest micro step: 64 * Highest response frequency: 200Kpps * Current of winding will be reduced by approximately 50% when no step pulse command is received for 0.1 second * Bipolar constant current chopping mode * Opto-isolated signal I/O * Drive current is continuously adjustable from 0.5A/phase to 3A/phase * Single power supply voltage from 12V to 40VDC.

The DVS278 is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 24V to 80VDC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 57mm to 86mm outside diameter, regulated phase current from 2.0A to 7.2A. The highest micro step is 40000ppr.
