APPARATUS, SYSTEM, AND METHOD FOR EFFICIENTLY CONTROLLING A HUB MOTOR

摘要

A stator (104) is attached to a shaft (110). Coils (114) are embedded in the stator (104) in a circular pattern. Two rotors (102) are coupled to the shaft (110) with the stator (104) between them. Permanent magnets (106) are embedded in each rotor (102). Each magnet (106) and core (116) has a similar cross-section. The magnets (106) are positioned in a circular pattern corresponding to the coils (114). The magnets (106) are positioned so when a coil (114) aligns with a magnet (106) a next coil (114) aligns between two magnets (106). Shorting bars (204) connect exterior edges of the magnets (106). A sequence control (402) connects each coil (114) so current flows in a coil (114) and the sequence control (402) disconnects and reconnects the coil (114) with current flowing in the opposite direction when a set of permanent magnets 106 aligns with a coil (114).
