Pulley assisted electromagnetic water pump

An electrically and mechanically driven automotive accessory, comprising:

• a housing;
• a shaft rotatably supported in said housing, said shaft extending along a longitudinal axis between an input end and an output end;
• an electric motor comprising a stator assembly and a rotor assembly that is rotatable relative to said stator assembly, said electric motor being configured to create a primary torque flow path when said electric motor is activated;
• said stator assembly fixedly mounted to said housing;
• said rotor assembly fixedly mounted to said shaft such that said rotor assembly rotates with said shaft;
• a pulley rotatably supported on said input end of said shaft such that said pulley is rotatable relative to said shaft and said rotor assembly;
• and
• a pulley assist mechanism including a plurality of claw-pole structures arranged circumferentially about said rotor assembly and an electromagnet configured to induce a magnetic field between said claw-pole structures and said pulley to create a secondary torque flow path between said pulley and said rotor assembly when said electromagnet is activated.
