Abstract
A motor control device includes a base board, a drive board including switching devices including switching elements for power conversion, disposed along a plane intersecting the base board, and attached to the base board, and a board including a processor configured to execute computation processing for controlling the switching devices, disposed along a plane intersecting the base board, and attached to the base board.
Claims20
A motor control device comprising:
- a base board;
- a drive board including a switching device for power conversion, the drive board being disposed along a plane intersecting the base board and attached to the base board;
- a control board including a first processor configured to execute computation processing for controlling the switching device, the control board being disposed along a plane intersecting the base board and attached to the base board;
- and
- a second processor mounted on the base board and interposed between the first processor as mounted on the control board and the switching device as mounted on the drive board,
- wherein the second processor is configured to execute the computation processing for controlling the switching device, in cooperation with the first processor, in response to an input from the first processor.
