Voltage compensation of mini-electrical motor e.g. for dental tool, involves digitally increasing/reducing drive pulse oscillation, and compensating voltage dips in analogue form by loading over integration time

摘要

The method involves compensating load-dependent voltage dips with voltage compensation, so that the motor (7) is driven via an RI regulator unit. At each time point a drive pulse oscillation can be increased or reduced digitally and the voltage dips can be compensated in analogue manner by loading over an integration time that is implemented using an energy storage device.
