MOTOR INCLUDING A PLURALITY OF CORE COLUMNS ARRANGED IN CONCENTRIC CIRCLE, MAGNETIC FLUX EMITTING PLATES ARRANGED AT ENDS OF CORE COLUMNS, AND STATOR COIL WOUND ON CORE COLUMNS

摘要

PURPOSE: A motor is provided to allow for ease of winding, reduce an amount of use of copper wire, and reduce parts count and costs. CONSTITUTION: A motor(10) comprises a stator(36) and a rotor(14). The stator is made of a magnetic material. A plurality of core columns(24) are arranged into a concentric circle centering from a rotary shaft and protruded along the rotary shaft from a base. A magnetic flux emitting plate(26) is arranged upright at a front end of each of the core columns. The magnetic flux emitting plate has a surface directed toward the rotary shaft. A stator coil(34) is wound on each of the core columns. The rotor is arranged to rotate on inner or outer surfaces of the magnetic flux emitting plates.
