 Origin Italy
 Model Number Asic EEA001
 Brand Name Ever Elettronica

 

 

 

 

Introduction

 

 

 

The ASIC EEA001 is a complete controller of enhanced, high performance, drives for stepping motors integrating the functions of sequencer and power stages control and protection against overcurrent, over & under-voltage, over-temperature.

 

Mastered by the standard step motor drive's controls (Step, Direction, Enable) it ensures the highest motor's performances through the execution of 

Micro-stepping movements at high step resolution (up to 1/256) permitted by no odd harmonics sinusoidally shaped winding currents (Maximum step frequency: 2,56 MHz).

 

The ASIC also allows to set a smoothing factor to optimize the drive and motor performances in terms of:

 

- H

 

 

igh speed and torque at shaft 

- Low heating of the drive

 

 

 

 

- No vibrations 

 

- Low heating of the motor

 

- N

 

o resonances 

- Very low mechanical noise
