Product Description:
The HMV01.1R-W0045-A-07-NNNN-AA is a supply module produced by Bosch Rexroth Indramat in the HMV IndraDrive Supply Units series. It serves as the DC bus supply for multi-axis IndraDrive systems, feeding shared bus energy to connected inverter sections and absorbing returned energy during braking. This arrangement supports common bus operation in machine tools, packaging lines, and material-handling equipment, where several axes can share available power within one cabinet. By centralizing the power conversion stage, the module reduces the need for separate energy-handling components at each axis and keeps cabinet integration more compact.
Its DC link is rated at DC 700 V, which matches standard IndraDrive inverters and supports the operating level used by the connected power section. A continuous output of 45 kW allows the unit to supply or absorb substantial power for dynamic motion profiles without immediate overload concerns. The regenerative power stage sends excess braking energy back to the AC supply instead of converting it into waste heat inside the cabinet. Thermal control uses internal air cooling with an integrated blower, so cabinet air moves across the heat sink without external ductwork. The housing has an IP20 rating, which helps protect against accidental finger contact with live parts but still requires installation in an enclosed electrical cabinet.
The module is built as Design version 1, which keeps the mounting arrangement and terminal layout consistent within that revision. It is also listed as Series version 01, indicating the applicable product generation within the IndraDrive platform. Because this unit is intended as the central supply section rather than a drive axis, it is paired with separate inverter modules that draw from the common DC bus during acceleration and return energy to it during deceleration. That operating role makes it suitable for systems with frequent speed changes, coordinated axis motion, or repeated braking cycles that benefit from shared bus energy management.
