Driver for 3-phase hybrid stepper motor

Q3HB64MA introduction:

Q3HB64MA is a constant angle and constant torque microstepping driver. This type of drivers supplies regulated phase current for voltage from 12V-40V DC. It is designed
for use with the 3-phase hybrid stepper of all kinds with 42-86mm outside diameter
and 5.8A current max. The circuity it adopts is similar to the circuit
of servo control in theory which enables the motor run smoothly at low speed nearly
without vibration and noise, output much greater torque at high speed than 2-phase
and 5-phase hybrid stepper. The precision of location is up to 60,000 steps/rev.

Features:
High reliability, low cost
16 channel constant angle constant torque microsteps. Highest resolution up to 60,000
steps/rev
Unique control circuitry
Highest response frequency up to 200Kpps
Winding current will be reduced to set value when no step pulse command is received
for 0.1 seconds
Bipolar constant current chopping mode
Optically isolated signals I/O
Driver current is continually adjustable from 0.5A/phase to 5.8A/phase
Single power supply (DC12-40V)
