NON-CONTACT MAGNETIC COUPLER FOR FOOD PROCESSING APPLIANCE HAVING SMALL BRUSHLESS PERMANENT MAGNET MOTOR

摘要

A food processing appliance (12) includes a container (20) having a rotational processing assembly (24) that includes an inner portion of a magnetic coupler (10). A base (30) has a drive system (32) for providing a rotational drive force (16). A drive rotor (40) selectively transfers the rotational drive force (16) to the magnetic coupler (10). The drive rotor (40) includes a plurality of drive-magnetic members (42) that form an outer portion (62) of the magnetic coupler (10). The inner portion (60) and outer portions (62) of the magnetic coupler (10) selectively and magnetically engage to form an engaged position (46). The engaged position (46) is further defined by the inner portion (60) being completely separated from the outer portion (62) to define a gap (52) therebetween.
