ABSTRACT:
A friction braking system located entirely inside an induction motor of an appliance quickly stops rotation of the rotor in the appliance motor, for example such as a food processor, whenever the A.C. electrical power is turned off. Thus, rotation of any tool being operated in the appliance is quickly stopped, whenever the electrical power is interrupted. The rotor in the induction motor is axially slidably mounted on the motor shaft and is keyed to the shaft for permitting axial shifting displacement of the rotor relative to the stator while preventing any angular displacement of the rotor relative to the shaft. Consequently, the rotor and shaft always turn and stop as a function unit. A friction brake lining is affixed within the motor housing offset from the axis of the motor shaft as far as practicable. A disc brake mounted onto the rotor has an annular friction braking surface positioned for engagement against the brake lining. The rotor is arranged for an axial thrust to shift the rotor in an axial direction away from its normal operating position aligned with the stator, whenever the electrical power is interrupted, thereby applying friction braking action quickly and at a relatively large moment arm as compared with the radius of the rotor for effective braking. The brake disc may include motor-cooling fan blades. An inverted V-shaped brake surface configuration is also shown for enhancing braking action.
