Abstract

A driver for motors according to the present invention is provided with: an aluminum substrate (10) which forms one surface of a housing; an insulating layer (11) which is formed on a surface of the aluminum substrate (10); a plurality of electronic elements (13) which are bonded onto a surface of the insulating layer (11), said surface being on a side opposite to the aluminum substrate (10); and a resin member (14) that covers the surface onto which the electronic elements (13) are bonded. This driver for motors is characterized in that the resin member (14) is obtained by integrating a mold resin part (20) which covers the electronic elements (13) from the upper surface side, a connector (21) which is electrically connected to the electronic elements (13), and a fitting part (22) which is used for fitting to a motor.

First claim

1 . A driver for motors, comprising:
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 to the insulating layer at a surface on a side opposite to the aluminum substrate; and a resin member that covers the surface onto which the electronic elements are bonded, wherein the resin member is obtained by integrating a mold resin part which covers the electronic elements from an 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.

2 . The driver for motors according to claim 1 , wherein
the fitting part of the resin member comprises a frame capable of accommodating the electronic elements, and the mold resin part is filled in the frame.

3 . The driver for motors according to claim 2 ,
wherein a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer is black.

4 . The driver for motors according to claim 1 , wherein a heat sink is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

5 . The driver for motors according to claim 1 , wherein one of the plurality of electronic elements is a memory, and
a connector for writing to the memory is arranged as the connector.

6 . The driver for motors according to claim 1 , wherein the electronic elements are used as a control part for a motor that drives a cooling fan.

7 . The driver for motors according to claim 6 , wherein
a ventilation area of the cooling fan driven by the motor is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

8 . The driver for motors according to claim 2 , wherein a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer is black.

9 . The driver for motors according to claim 2 , wherein a heat sink is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

10 . The driver for motors according to claim 3 , wherein a heat sink is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

11 . The driver for motors according to claim 2 , wherein one of the plurality of electronic elements is a memory, and
a connector for writing to the memory is arranged as the connector.

12 . The driver for motors according to claim 3 , wherein one of the plurality of electronic elements is a memory, and
a connector for writing to the memory is arranged as the connector.

13 . The driver for motors according to claim 4 , wherein one of the plurality of electronic elements is a memory, and
a connector for writing to the memory is arranged as the connector.

14 . The driver for motors according to claim 2 , wherein the electronic elements are used as a control part for a motor that drives a cooling fan.

15 . The driver for motors according to claim 3 , wherein the electronic elements are used as a control part for a motor that drives a cooling fan.

16 . The driver for motors according to claim 4 , wherein the electronic elements are used as a control part for a motor that drives a cooling fan.

17 . The driver for motors according to claim 5 , wherein the electronic elements are used as a control part for a motor that drives a cooling fan.

18 . The driver for motors according to claim 14 , wherein
a ventilation area of the cooling fan driven by the motor is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

19 . The driver for motors according to claim 15 , wherein
a ventilation area of the cooling fan driven by the motor is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.

20 . The driver for motors according to claim 16 , wherein
a ventilation area of the cooling fan driven by the motor is arranged on a surface of the aluminum substrate which is positioned on a side opposite to the insulating layer.
