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.
