Description

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. Designed to operate from 20 to 82Vdc, they are suitable for a wide range of DC applications. The unbeatable compact design, low cost and reliability ensures the MicroB's success as a market.
