Embodiment approach 1

[0028] Hereinafter, the motor control device according to Embodiment 1 of the present invention will be described with reference to the drawings. figure 1 A configuration of a motor drive device including the motor control device according to Embodiment 1 is shown, figure 2 A control board of the motor control device according to the first embodiment is shown. In addition, the same code|symbol is attached|subjected to the same or a corresponding part in each drawing.

[0029] In the control board 1 of the motor control device ( figure 1 Indicated by a dotted line in ), a plurality of electronic components for controlling the driving of the motor, that is, the motor 4, are installed. The control board 1 performs control calculations for driving the motor 4 and drives the inverter 5 for driving the motor 4 . In addition, in Embodiment 1, a three-phase brushless motor is used as the motor 4 .

[0030] The microcomputer 11 performs control calculations for driving the motor 4...

Embodiment approach 2

[0066] Figure 5 ~ Figure 7 The separation tape of the control substrate according to Embodiment 2 of the present invention is shown. In this second embodiment, a case where the separation tape 30 includes a plurality of through holes 31 or notches 32 will be described as a modified example of the separation tape 30 described in the above-mentioned first embodiment. In addition, since the configuration of the motor drive device according to the second embodiment is the same as that of the above-mentioned first embodiment, the figure 1 Detailed description is omitted.

[0067] exist Figure 5 In the example shown, the separation belt 30 has three through-holes 31b, 31c, and 31d of the same shape, and these are arranged on a straight line. In addition, the number of through holes is not limited to three, and may be two or four or more. In addition, in Figure 5 Among them, although the three through-holes 31b, 31c, and 31d each have the same shape, they do not need to have ...

Embodiment approach 3

[0074] Figure 8 ~ Figure 9 The separation tape of the control substrate according to Embodiment 3 of the present invention is shown. In Embodiment 3, a case where a plurality of separation tapes 30 are provided on a substrate 100 will be described as a modified example of the separation tape 30 described in Embodiment 1 above. In addition, since the structure of the motor driving device according to the third embodiment is the same as that of the above-mentioned first embodiment, the figure 1 , omitting detailed description.

[0075] exist Figure 8 In the illustrated example, the separation band 30 composed of one elongated through-hole 31 is disposed at two upper and lower positions of the substrate 100 . In addition, in Figure 9 In the illustrated example, a separation band 30 including one elongated through hole 31 is disposed on the upper portion of the substrate 100 , and a separation band 30 having a notch 32 a and a through hole 31 d is disposed on the lower port...

Abstract

A substrate (100) has a separating zone (30) configured from one long and narrow through-hole (31) in a region closer to an end portion than a central portion thereof. A first group electronic component (10) serving as a source of generation of heat and electrical noise is disposed in a first region (101) on the central portion side from the separating zone (30) of the substrate (100). A second group electronic component (20) that needs to eliminate the influence of heat or electrical noise from another component as much as possible is disposed in a second region (102) on the end portion side from the separating zone (30) of the substrate (100).

Description

technical field [0001] The present invention relates to a control device for a motor. Background technique [0002] The motor control device includes a control board mounted with a plurality of electronic components for controlling the drive of the motor. Conventionally, there is known a control device that controls the timing of on and off of semiconductor switching elements constituting an inverter for driving a motor. [0003] For example, the electric power steering apparatus disclosed in Patent Document 1 includes a control board in which electronic components such as a microcomputer for driving and controlling a motor are mounted on a multilayer printed board by soldering. In this example, a substantially rectangular control substrate is provided with a hole at the center thereof through which the shaft of the motor passes.
