  • Patent number: 4241302
    Abstract: An improved capacitive braking system is provided for fractional Horsepower induction motors in home appliances, for example in a food processor of the type having a working bowl mounted on a housing containing the induction motor, with a shaft in the bowl for removably supporting a rotary food processing tool to be driven by the induction motor. The new braking system rapidly halts the coasting motion of the motor rotor and tool after the motor has been disconnected from the electric power line. A first switch is provided to control the application of electrical energy to the induction motor for sustained operation, and a second "pulse" switch is provided to control the application of electrical energy to the induction motor for brief surges of momentary operation. The braking system includes a second capacitor which is external to the induction motor and distinct from the starting capacitor normally associated with an induction motor.
