A magnetic device mounting system is disclosed, such as for use in electrical cabinets for distribution of power via power bus bars. The system includes a common mode magnetic device that has an opening configured to receive extensions of a set of parallel bus bars. A non-conductive support is provided, along with a conductive extension, the non-conductive support and extension being configured to coordinate to engage the opening and to support the common mode magnetic device via attachment to the bus bar.

Common mode magnetic device for bus structure

The present disclosure is generally directed to efficiently cooling converter and inverter components of a drive system. Present techniques relate to a motor drive duct system that facilitates efficient cooling and access to motor drive components. The motor drive duct system includes duct channel paths that are parallel and adjacent to one another. The duct system includes a converter section that houses a converter heat sink, an inverter section that houses an inverter heat sink, an exhaust section, and an air inlet section. The converter section and the inverter section are configured to be attached and detached from each other at end sections that are angled to receive one another. Further, the inverter section, converter section, and air inlet section are configured to roll into and out of a cabinet, which facilitates access to field wiring.

Cooling duct attachment and sealing for a motor drive

The present invention relates generally to tuning the flow of cooling air across converter and inverter heat sinks in a motor drive system. More specifically, present techniques relate to motor drive duct systems having parallel cooling air duct channels dedicated to providing cooling air for a converter heat sink and an inverter heat sink, respectively. In particular, a first duct channel through an inverter duct and a converter duct is dedicated to providing cooling air to the converter heat sink without cooling the inverter heat sink, whereas a second duct channel through the inverter duct and the converter duct is dedicated to providing cooling air to the inverter heat sink without cooling the converter heat sink.
