MOTOR SYSTEM, MOTOR, AND DRIVE CIRCUIT

摘要

A motor system includes a motor and a circuit. The motor includes a mover and a stator. The mover includes mover side protrusions. The stator includes first and second stator side protrusions, and first and second coils respectively wound around the first and second stator side protrusions. When a center of one first stator side protrusion among the first stator side protrusions in a circumferential direction is aligned with a center of one mover side protrusion in the circumferential direction, a center of one second stator side protrusion among the second stator side protrusions in the circumferential direction is out of alignment with a center of another mover side protrusion in the circumferential direction. The circuit drives the motor, and includes first and second circuits to provide a current respectively through the first and second coils.
