Printed circuit board with ground conductor for electric motor, and electric motor

Abstract

A printed circuit board (PCB), in particular for an electric motor, has two opposite main surfaces with at least one main surface carrying electrical components. A plurality of outer end faces extend between the two opposite main surfaces. One of the outer end faces is provided with a metallization that is connected to a ground conductor on the PCB.

Claims

1. A printed circuit board (PCB) for an electric motor comprising: two opposite main surfaces wherein at least one of the two opposite main surfaces carries electrical components; anda plurality of outer end faces that extend between the two opposite main surfaces, one of the plurality of outer end faces being provided with a metallization that is connected to a ground conductor on the PCB.

2. The PCB of claim 1 wherein the metallization extends over an entire surface of the one of the plurality of outer end faces.

3. The PCB of claim 1 wherein the metallization extends over only a portion of the one of the plurality of outer end faces.

4. The PCB of claim 1 wherein the one of the plurality of outer end faces that carries the metallization comprises a flat surface.

5. The PCB of claim 1 wherein the one of the plurality of outer end faces that carries the metallization has a groove.

6. An electric motor having a PCB comprising: two opposite main surfaces wherein at least one of the two opposite main surfaces carries electrical components; a plurality of outer end faces that extend between the two opposite main surfaces, one of the plurality of outer end faces being provided with a metallization that is connected to a ground conductor on the PCB; anda motor ground contact that contacts the metallization on the one of the plurality of outer end faces of the PCB.

7. The electric motor of claim 6 wherein the motor ground contact is formed as an elastic tab.

8. The electric motor of claim 6 including a holder, into which the PCB can be slidingly inserted so that the metallization comes into contact with the motor ground contact.
