A blending appliance includes a housing having a motor compartment and a jar receiving portion spaced laterally therefrom. The jar receiving portion is disposed below an upper housing. A motor is disposed in the motor compartment is adapted to drive a blade assembly of the jar through a magnetic coupling system. The motor is connected to a blade assembly disposed within the jar through a series of gears or belts, and finally through a magnetic coupler. The magnetic coupler is configured such that it stores kinetic energy while the motor is running at a high speed, and releases the stored energy when the motor is running at a slower speed.

1. A method of reducing a bridging effect in a blending appliance, the method comprising the steps of: providing a blending appliance having a housing with a jar receiving area, a motor and a first magnetic coupler, wherein the first magnetic coupler is powered by the motor for rotation within an interior of the housing;providing a blender jar removeably supported in the jar receiving area of the housing, wherein the blender jar includes a receptacle portion disposed over a base portion, wherein the base portion of the blender jar includes a second magnetic coupler rotatably housed therein, wherein the second magnetic coupler is magnetically coupled to the first magnetic coupler for rotation therewith when the blender jar is received in the jar receiving area, and further wherein the second magnetic coupler is further coupled to a blade assembly disposed in the receptacle portion of the blender jar;providing ingredients to the receptacle portion of the jar;initiating an automated blending sequence wherein the automated blending sequence includes the steps of: rotating the first magnetic coupler at a first rotational speed using a first setting of the motor;processing the ingredients in the receptacle portion of the blender jar with the blade assembly rotating at a first rotational speed associated with the first setting of the motor for an amount of time sufficient to induce a bridging effect in the ingredients within the receptacle portion of the blender jar;decreasing the first rotational speed of the first magnetic coupler to a second rotational speed using a second setting of the motor;processing the ingredients in the receptacle portion of the blender jar with the blade assembly rotating at a second rotational speed associated with the second setting of the motor for an amount of time sufficient to disrupt the bridging effect in the ingredients within the receptacle portion of the blender jar; andincreasing the second rotational speed of the first magnetic coupler to a third rotational speed after the bridging effect is disrupted using a third setting of the motor. 2. The method of claim 1, wherein the third rotational speed of the first magnetic coupler is greater than or equal to the first rotational speed. 3. The method of claim 1, wherein the third rotational speed of the first magnetic coupler is less than or equal to the first rotational speed. 4. The method of claim 1, wherein the first setting of the motor includes a rotational speed of the motor of about 5000 rpm to about 6000 rpm. 5. The method of claim 4, wherein the second setting of the motor includes a rotational speed of the motor of less than 1000 rpm. 6. The method of claim 5, wherein the amount of time sufficient to induce a bridging effect is an amount of time in a range from about 2 seconds to about 6 seconds. 7. The method of claim 6, wherein the rotational speed of the blade assembly is about 0.925 times the rotational speed of the motor. 8. A method of reducing a bridging effect in a blending appliance, the method comprising the steps of: providing a blending appliance having a housing with a jar receiving area, a motor and a first magnetic coupler, wherein the first magnetic coupler is powered by the motor for rotation within an interior of the housing;providing a blender jar removeably supported in the jar receiving area of the housing, wherein the blender jar includes a receptacle portion disposed over a base portion, wherein the base portion of the blender jar includes a second magnetic coupler rotatably housed therein, wherein the second magnetic coupler is magnetically coupled to the first magnetic coupler for rotation therewith when the blender jar is received in the jar receiving area, and further wherein the second magnetic coupler is further coupled to a blade assembly disposed in the receptacle portion of the blender jar;providing ingredients to the receptacle portion of the jar;initiating an automated blending sequence wherein the automated blending sequence includes the steps of: rotating the first magnetic coupler at a first rotational speed using the motor to further rotate the second magnetic coupler via magnetic torque;processing the ingredients in the receptacle portion of the blender jar with the blade assembly at the first rotational speed of the second magnetic coupler for an amount of time sufficient to induce a bridging effect in the ingredients within the receptacle portion of the blender jar;decreasing the first rotational speed of the second magnetic coupler to a second rotational speed;processing the ingredients in the receptacle portion of the blender jar with the blade assembly at the second rotational speed of the second magnetic coupler for an amount of time sufficient to disrupt the bridging effect in the ingredients within the receptacle portion of the blender jar; andincreasing the second rotational speed of the second magnetic coupler to a third rotational speed. 9. The method of claim 8, wherein the third rotational speed of the second magnetic coupler is greater than or equal to the first rotational speed. 10. The method of claim 8, wherein the third rotational speed of the second magnetic coupler is less than or equal to the first rotational speed. 11.
