Abstract
Official abstract text for this publication.
In a circuit board, a control pattern portion in which control circuit patterns are formed and a drive pattern portion in which drive circuit patterns are formed are formed in different regions. A recessed portion is formed in a base, and the drive pattern portion is fixed to the base such that insulation between a drive circuit and the base is maintained and the control pattern portion is arranged above the recessed portion. In this way, a space in which a circuit element is able to be mounted is formed between the control pattern portion and the recessed portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A control unit for an electric motor, including a circuit board having a multilayer structure in which multiple circuit conductive layers having circuit patterns are laminated with non-conductive layers interposed between the circuit conductive layers, and a base to which the circuit board is fixed, wherein the circuit board has a control pattern portion in which control circuit patterns constituting wirings of a control circuit that outputs a control signal…
