Model No.︰Q3HB64MA
Brand Name︰JB
Country of Origin︰China
Unit Price︰-
Minimum Order︰1 pc
Product Description
Q3HB64MA is a constant angle and constant torque stepper motor drive. The driven voltagerange from DC12V to 40V. It can match 3-phase hybrid stepper motors whose rated current is under5.8A and shaft diameter range from 42mm to 86mm. Owe to bipolar constant chopping circuit, it can make motors low noise and operated smoothly when low speed; the torque is much greater than 2-phase and 5-phase stepper motor when high speed. It is widely used in small-sized numerical control device such as medical machine, robot, instrumetation, curving machine, laser labeling machine, inner laser curving machine.
Feature
● High performance, low price
● 16 channels constant angle and constant torque, the highest subdivision is 60000 s/r
● Special control circuit
● Highest response frequency: 200Kpps
● The motor phase current is reduced to approximately 50% of the set current value 100ms after receiving the last pulse edge
● Bipolar constant current chopping circuit
● Opto-isolated input/output
● Driven current is adjustable continuously from 0.5A/phase to 5.8A/phase
● Single power supply, voltage arrange from DC12V to 40V
Caution
1. Don’t reverse the power supply, supply voltage shouldn’t exceed DC40V.
2. Input control signal is 5V, current-limiting resistance should be connected when over 5V.
3. Alarm indicator lights and the drive shuts off if the drive temperature is over 70℃. It doesn’t work until the temperature falls to 50℃. The heat sink is needed when overheat occurs.
4. Alarm indicator lights when overcurrent (short of load) occurs. Please check motor’s connection and other shorts and turn the power supply on after removing the trouble.
5. Alarm indicator lights when undervoltage (the voltage is less than DC12V) occurs.
