Detailed Product Description

Stepper Motor Driver

Q2HB44

Introduction:

Full/half driver supplies regulated phase current for supply voltage from 12 to 40V DC. It is designed for use with the 2-phase hybrid stepper with 42-86mm outside diameter, 6 or 8 leads and 4 arms.

Features:
High reliability, low price
Highest response frequency up to 200kpps
Current of winding will be reduced by 50%
When no step pulse, command is received for 0.1 second
Bipolar constant current chopping mode
Optically isolated signal I/O
Driving current is continually adjustable from 0.5A/phase to 4A/phase
Single power supply from 12v to 24V DC

Q2HB44MA (B)
Introduction:
Constant angle, constant torque microstep driver supplies regulated phase current for supply voltage from 12 to 40V DC. It is designed for use with the 2-phase hybrid stepper with 42-86mm outside diameter, 6 or 8 leads and 4 arms. The driver adopts a unique control circuit. The benefits include: reducing motor noise, running more smoothly, improving motor performance by 30% at high speed and reducing driver heating by 50%.
