A driver for motors according to the present invention is provided with: an aluminum substrate () which forms one surface of a housing; an insulating layer () which is formed on a surface of the aluminum substrate (); a plurality of electronic elements () which are bonded onto a surface of the insulating layer (), said surface being on a side opposite to the aluminum substrate (); and a resin member () that covers the surface onto which the electronic elements () are bonded. This driver for motors is characterized in that the resin member () is obtained by integrating a mold resin part () which covers the electronic elements () from the upper surface side, a connector () which is electrically connected to the electronic elements (), and a fitting part () which is used for fitting to a motor.

Driver for motors

A driver is provided. A driver () includes an aluminum substrate () to which electronic components () are joined, and a resin member () that covers the electronic components (). The resin member () has a first resin portion () that covers the electronic components () and a second resin portion () that covers the first resin portion (). The hardness of the first resin portion () is lower than the hardness of the second resin portion ().

Driver

A control apparatus includes a terminal that includes a plurality of electrically conductive plate materials, a base member on which the terminal is provided, and an electronic component that includes a plurality of electronic elements which are electrically connected to the terminal, wherein a window part from which part of the terminal is exposed is formed on the base member so as to penetrate in a thickness direction of the base member, and an extension electronic component arrangement part is provided on the base member, and wherein the electronic component is electrically connected to the terminal that is exposed from the window part, and an electronic component is electrically connectable selectively between a plurality of bus bars by the extension electronic component arrangement part.

Control apparatus that controls driving of a driven body

A controller () includes a primary molded portion () in which a resin molded body () is integrated with a bus bar () using a resin, causing one end of the bus bar () to function as a connector terminal which protrudes into connector portions () to (), and configured to form electronic component disposition portions (a) to (d) in which an electronic component () is disposed and a power device disposition portion () in which a power device () is disposed, and a secondary molded portion () integrated with the electronic component (), the power device (), and the primary molded portion () in a state in which the electronic component () is disposed at the electronic component disposition portions (a) to (d) and the power device () is disposed at the power device disposition portion ().

Controller and manufacturing method thereof

The invention provides an electric motor in which a cost is reduced by reducing a number of the parts, and an electric motor in which a freedom of placement is increased. A motor assembly has a yoke and a front bracket closing an open end of the yoke. The front bracket is formed in a closed-end cylindrical shape by an aluminum die casting, and a brush holder for holding a brush is received in an inner portion. A motor controller for controlling the motor assembly is formed as an electronic circuit having a communication portion, a control portion and a driver portion, and this electronic circuit is mounted on an inner peripheral surface of the front bracket. Further, the electronic circuit constituting the motor controller may be mounted on the brush holder.
