Introduction
Introduction
A motor control system will obviously include a motor and inverter, as well as fuses for
safety. If you are connecting a motor to the inverter on a test bench just to get started,
that's all you may need for now. But a fully developed system can also have a variety of
additional components. Some can be for noise suppression, while others may enhance
the inverter's braking performance. The figure below shows a system with several
possible optional components, and the table gives part number information.
