  • Motor actuator having position detector
    Patent number: 6107712
    Abstract: A motor actuator has a position detector provided with a pulse plate made of resin and a sliding contact. The pulse plate has a first conductive unit and a second conductive unit. The sliding contact has an input contact and an output contact. The first conductive unit makes contact with the input contact and the second conductive unit makes contact with the output contact so that a pulse signal is obtained by rotation of the pulse plate. A plurality of slit portions are formed on the first conductive unit by exposing the resin material of the pulse plate so that grease is collected in a boundary portion of each of the slit portions due to a difference in thickness between the slit portions and a conductive portion of the first conductive unit.
