Stepper Motor Driver:
DQ2722MA is a new-generation digital 2-phase stepper motor driver based on DSP control. The driver combines advanced DSP control technique and unique control circuit. The driver voltage is AC110-230V and driver current is below 7.0A. The driver can be used for types of 2-phase stepper motor with external diameter 86-130mm. The driver adopts circuit similar to servo control, so the motor can run smoothly with little vibration and noise. And the maximum positioning accuracy could reach 40,000 steps/rev. The product is widely used in big and medium-sized CNC equipment with higher resolution, such as engraving machine, medium-sized CNC machine tool, computer-controlled embroidery machine, packing machine, etc.
Features：
High performance, low price. The driver features 16-grade micro-stepping with equal angular degree and constant torque; the highest resolution may reach 40,000steps/rev. The highest response frequency can reach 500Kpps When the step-by-step impulse has halted for over 100ms, the coil current will automatically reduce to half of the set value, to effectively reduce motor warming. Photoelectric isolation signal input/output. Driver current from 1.0A / phase to 7.0A / phase, adjustable with 16 grades. Single power input, voltage range: AC 110V to 230V.
Application:
Our Stepper Motors are used on small to mid-sized CNC mills or milling machines, CNC lathes, Pick-n-place machines,Laser Engravers and Laser Cutters, Vinyl Sign Cutters, CNC Plasma Cutters, and CNC Foam Cutters. Carver machine ,Dispenser,Automation,3D Printer,Stage lighting,instrument, laser equipment,scanner and so on.These motors have been used in precision telescope positioning systems and robots.
