CNC Stepper Motor Driver 2 Phase Micro CNC Stepper Driver Controller 2M982 AC 7.8A 24-80V 200KHz
Description:
- 2M982 is a cost-effective high-perfomance bi-polar 2 phase micro-stepping drive, applying pure-sinusoidal current controltechnique. It is best suited for the applications that desired extreme low noise and heat,It operates well in an encironment, where electricity supply experience instability and fluctuation.
- Suitable for a wide range of stepping motors, from NEMA 23/34/42. It can be used in various kinds of machines, such as X-Y tables, engraving machines, labeling machines, laser cutters, pick-place devices, and so on. Particularly adapt to the applications desired with low noise, low heating, high speed and high precision.
