The MicroFlex digital servo drive provides a cost effective, high performance solution
for your servo drive needs. Incorporating a digital signal processor (DSP) for motor control, MicroFlex
supports features such as digital filters to help reduce resonance within the machine.
MicroFlex is ideally matched to Baldor’s range of brushless high performance rotary servo motors and
linear motors.
MicroFlex is a totally digital drive, utilizing a high performance
Digital Signal Processor (DSP) for motor control. A 16KHz Space
Vector Modulation (SVM) and 62.5μS current loop update, ensure
optimal current regulation and dynamic performance for today’s
demanding applications.
By controlling the IGBT power devices using SVM instead of the
more usual carrier based pulse width modulation (PWM), users
can run servo motors at typically 15% higher speeds with reduced
switching losses and harmonics. In today’s world of increased
productivity, this can translate directly into greater machine
throughput.
