Abstract

See full text

A printed circuit board and an electric filter. The printed circuit board is arranged to accommodate an electric circuitry on one side, and an electrically conductive material on the other side which forms a common ground point with the electric circuitry and a device contacting the conductive material. The electric filter for filtering electric signals of a DC motor includes a freewheeling diode coupled in parallel to the motor, a capacitor coupled in parallel to the motor, where a ground terminal of the capacitor is coupled to a chassis of the motor, a low pass filter including a ferrite bead and another capacitor is connected to each motor terminal (M+, M−), and a resistor-capacitor filter is coupled in parallel to the motor.
