  • Control device for a motor unit of a food processor
    Patent number: 7098616
    Abstract: A control device includes a control module controlling a polarity switching unit connected electrically to a motor unit of a food processor to provide a first current path for an input power signal through the motor unit when the control module is operated in a processing mode, and further controlling the polarity switching unit to provide a second current path for the input power signal through the motor unit when the control module is operated in a braking mode. A power control unit is connected electrically to the motor unit and the control module, and controls the power control unit such that the power control unit reduces an amount of the input power signal that flows through the second current path during a braking period when the control module is operated in the braking mode.
