DQ420MA is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from
12VDC to 36VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 20mm
to 42mm outside diameter and less than 2.0A phase current. This circuit that it adopts is similar to
the circuit of servo control which enables the motor to run smoothly almost without noise and vibration.
Holding torque when DM420A rund at high speed is also significantly higher than the other two-phase
drivers, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size
numerical control devices such as curving machine, CNC machine, and computer embroider machine,
packing machines and so on. |
