H2W Tech Release New High Stability Stepper Driver

The SD-03-48-125 from H2W Technologies is a cost effective, high performance, bi-polar, two phase micro-stepping drive which utilizes the pure-sinusoidal current control technique. It is best suited for applications which require extreme low noise and heat. It operates well in an environment where input voltage may experience instability and fluctuation.

The general pseudo-sinusoidal current control technology used by most stepper drives produces a distorted sine wave and current ripple, resulting in vibration, noise and motor heating. This results in the motor degrading over time, reducing its performance and life.

With the automatic optimization speed control technique, the SD-03/48-125 stepper drive output is very stable with almost zero vibration and noise, performing close to a servo system. This allows the motor to operate smoothly. This is useful in applications which require low noise, low heat and high performance.

Drivers will be preset to match the continuous current specifications of any H2W linear stepper motor. Available from stock for immediate shipping.
