カーボンブラシ摩耗検出回路。In an electric motor with carbon brushes, a photocoupler light emitting unit (input) or a light emitting element such as a light emitting diode is connected through a resistor in parallel with the armature, and the spring that applies pressure to the carbon brushes contacts the carbon brush wear detection rod. At this time, a current flows through the light emitting element, converts it into an electrical signal, and the optical signal is sent to the output section of the photocoupler (
A carbon brush wear detection circuit that has functions such as driving a light receiving element (light receiving side) or a phototransistor, transmitting a carbon brush wear signal, and displaying a request to stop the city electric motor and replace the carbon brush.
