Micro B

 

 

MicroB drives have been designed as ultra compact modules suitable for all industrial automation requirements. They are an ideal solution for incremental motion control, high precision velocity and torque loop contouring control and positioning systems which require fast response, high torque at low speed, smooth speed control and high reliability.

The MicroB range operates from 20 to 82Vdc and drive motors of up to 600W. The MicroB Plus range operate from 20 to 270volts and drive motors of up to 4000W. Both are suitable for a wide range of DC applications. The unbeatable compact design, low cost and reliability ensures the MicroB's success.
