  • Actuator with electric motor and EMI reduction circuit
    Patent number: 9941773
    Abstract: An actuator includes a circuit board having an electromagnetic interference (EMI) reduction circuit. The actuator includes a motor having a motor casing mounted on the circuit board. A portion of the motor casing contacts a surface of the circuit board. The actuator includes an electrical contact conductively coupled to the EMI reduction circuit and mounted on the surface of the circuit board. The electrical contact establishes a conductive path between the EMI reduction circuit and the motor casing when the motor casing is mounted on the circuit board.
    Type: Grant

  • Actuator having a brushed DC electric motor and an EMI reduction circuit
    Patent number: 9077232
    Abstract: An actuator is shown and described. The actuator includes a brushed DC motor and a circuit board. The circuit board for the brushed DC motor includes an EMI reduction circuit and a mounting location for the brushed DC motor. The mounting location includes a resilient conductive member that is surface mounted on the circuit board at the mounting location. When the motor is mounted to the circuit board at the mounting location, the motor case contacts and at least slightly compresses the resilient conductive member, conductively connecting the motor case to the EMI reduction circuit.
